How to Tighten Skin Without Surgery: The Ultimate Guide to Non-Invasive Solutions

Alright, let's just get real for a moment, shall we? Who among us hasn't stood in front of the mirror, tilted our head just so, and gently pulled back the skin along our jawline or neck, wishing it would just… stay there? That subtle shift, that little upward lift, it’s like a secret yearning we all share. The desire for firmer, more resilient skin isn't about vanity, not really. It’s about feeling confident, about looking as vibrant and energetic on the outside as we often feel on the inside. And let’s be honest, the thought of going under the knife? For many of us, it’s a hard pass. The downtime, the cost, the sheer invasiveness of it all – it’s a big commitment, and frankly, it's just not for everyone.

This growing demand for alternatives, for ways to reclaim a more youthful skin texture without the dramatic step of surgery, isn't just a trend; it's a movement. We're living in an era where science and technology are constantly evolving, offering us a myriad of non-invasive solutions that were once the stuff of science fiction. From the foods we eat to the creams we apply, and even to the cutting-edge devices available in clinics, there's a whole world of possibilities waiting to be explored. This isn't about chasing some unattainable ideal of perfection; it's about harnessing knowledge and making informed choices to support our skin's natural resilience and beauty. So, if you're standing at that mirror, contemplating that gentle lift, and wondering if there's a less drastic path, you've come to the right place. Consider this your definitive, no-nonsense guide to navigating the exciting and ever-expanding landscape of non-surgical skin tightening. We're going to dive deep, peel back the layers (pun absolutely intended), and empower you with the knowledge to make real, impactful changes.

Understanding Skin Laxity: Why Skin Sags and What You Can Do

Let’s be frank: nobody wakes up one morning and suddenly has significantly sagging skin. It’s a subtle, insidious process, often happening so gradually that we barely notice it until one day, the reflection staring back at us seems… different. A little less taut, a little less firm. It's like finding a favorite sweater that’s stretched out over time – still familiar, but lacking that original crispness. Understanding why this happens is the first crucial step in figuring out what we can do about it. It’s not just about getting older; it’s a complex interplay of biology, environment, and even our daily habits that conspire to loosen our skin's grip.

Think of your skin as a finely woven, incredibly complex fabric, constantly under stress from both internal and external forces. Over time, this fabric begins to lose its inherent elasticity and structure, much like an old rubber band that’s been stretched too many times. This loss of firmness, medically termed skin laxity, isn't just a surface issue; it originates deep within the dermal layers. It manifests in various ways: a drooping jawline, jowls, loose skin around the neck (the dreaded "turkey neck"), fine lines deepening into wrinkles, and even a general loss of plumpness and bounce across the face and body. The psychological impact can be significant, too. It’s not just about aesthetics; it’s about feeling that the external appearance no longer matches the internal vitality, creating a disconnect that can chip away at self-confidence.

The journey to understanding skin laxity requires us to look beyond the superficial. We need to explore the microscopic battlefield where our skin cells are constantly fighting against degradation. It’s a story of proteins, cells, and environmental aggressors, all contributing to the gradual decline of our skin's structural integrity. While we can’t stop time, we can certainly equip ourselves with the knowledge and tools to mitigate its effects, slowing down the process and even, in many cases, reversing some of the visible signs. This isn't about magic; it's about science, consistency, and a little bit of self-love.

The Crucial Role of Collagen and Elastin in Skin Firmness

If skin firmness had a dynamic duo, a Batman and Robin, it would undoubtedly be collagen and elastin. These two proteins are the absolute bedrock of youthful, resilient skin, and understanding their individual roles and how they work in concert is paramount to any discussion about tightening skin. Imagine your skin as a mattress: collagen provides the firm, supportive springs, giving it structure and plumpness, while elastin is like the stretchy, resilient fabric cover that allows it to bounce back into shape after pressure. When these two start to falter, the mattress sags, loses its bounce, and develops indentations.

Collagen, making up about 80% of your skin's dry weight, is a fibrous protein that forms a robust scaffolding in the dermis, the layer beneath your skin's surface. It’s responsible for skin’s strength, rigidity, and overall structural integrity. There are many types of collagen, but types I and III are most prevalent in the skin, providing that essential framework. Think of collagen fibers as tiny, tightly wound ropes that crisscross and interlace, creating a dense, supportive network. This network keeps your skin plump, smooth, and resistant to wrinkles. However, from our mid-20s, our natural collagen production begins to decline by about 1% each year. This isn't a sudden drop but a slow, steady erosion, meaning the rate of collagen breakdown starts to outpace its synthesis. The existing collagen fibers also become more fragmented, weaker, and less organized, leading directly to a loss of firmness and the emergence of fine lines and wrinkles.

Elastin, on the other hand, is all about flexibility and recoil. As its name suggests, it gives skin its elasticity – the ability to stretch and then snap back into place. These fibers are much thinner and more sparse than collagen fibers, but they are incredibly powerful, acting like microscopic rubber bands. When you pinch your skin and let go, it’s elastin that allows it to immediately return to its original position. A healthy supply of elastin ensures your skin remains supple and resistant to permanent creasing. Unfortunately, elastin is even more vulnerable to degradation than collagen. Once elastin fibers are damaged, they are incredibly difficult for the body to repair or replace naturally. Unlike collagen, which the body can still produce (albeit at a slower rate), elastin synthesis virtually ceases in adulthood. So, when those elastin "rubber bands" become brittle, frayed, or broken, your skin loses its bounce, leading to persistent sagging and a diminished ability to recoil. This is why addressing both collagen and elastin is key to truly tightening the skin.

Common Causes of Skin Sagging Beyond Age

While age is undoubtedly a significant factor in skin laxity – a relentless march that none of us can fully escape – it’s crucial to understand that our skin's firmness isn't solely dictated by the number of candles on our birthday cake. There's a whole host of other culprits, a veritable rogue's gallery of environmental and lifestyle factors, that conspire to accelerate the degradation of that precious collagen and elastin, making us look older than our years. Identifying these non-age-related factors is empowering because, unlike time, many of them are within our control.

One of the most notorious offenders is sun exposure, or more accurately, unprotected sun exposure. We've all heard it before, but it bears repeating: UV radiation is a collagen and elastin annihilator. UVA rays, in particular, penetrate deep into the dermis, generating free radicals that act like tiny wrecking balls, breaking down the structural proteins and inhibiting the production of new ones. This process, known as photoaging, doesn't just cause wrinkles; it directly contributes to a leathery texture and significant skin laxity. I remember seeing a patient in my early days who had spent decades working outdoors without protection; their face was a roadmap of sun damage, but it was the profound lack of elasticity, the thin, crepey quality of their skin, that truly brought home the cumulative damage of UV. It’s not just about sunburns; it’s about the daily, insidious exposure that adds up over a lifetime.

Then there’s genetics, the wild card we have little control over. Just as some people are predisposed to certain hair colors or heights, others inherit a genetic blueprint that dictates their skin's natural collagen and elastin production rates, its repair mechanisms, and its overall resilience. If your parents or grandparents experienced significant skin sagging at an earlier age, you might unfortunately be predisposed to a similar fate. It’s a tough pill to swallow, knowing some battles are harder-fought due to DNA, but it doesn't mean the fight is lost. It just means you might need to be even more diligent with your preventative and corrective strategies. It's not an excuse to give up; it's a call to action to be proactive.

Significant weight loss is another major contributor to skin laxity, and it’s a bittersweet reality for many. While achieving a healthier weight is a triumph, the rapid or substantial reduction in fat volume beneath the skin can leave the overlying skin with nowhere to go. Imagine blowing up a balloon, stretching it out, and then quickly deflating it; the balloon doesn't immediately snap back to its original size. The skin, having been stretched to accommodate the larger body, often lacks the elasticity to fully retract once the underlying support is gone. This is particularly noticeable on the abdomen, arms, thighs, and face, where substantial fat loss can lead to loose, hanging folds of skin. It’s a common challenge for bariatric surgery patients, but even those who achieve weight loss through diet and exercise can experience it.

Furthermore, lifestyle choices play an enormous role. Smoking, for instance, is an absolute skin disaster. The nicotine constricts blood vessels, reducing blood flow and oxygen to skin cells, while the chemicals in cigarette smoke generate a massive influx of free radicals that directly attack collagen and elastin. It's like pouring acid on your skin's structural proteins. Poor nutrition, chronic stress, and inadequate sleep also contribute by hindering the body's natural repair processes and promoting inflammation. And let's not forget hormonal changes, particularly those experienced during menopause. The significant drop in estrogen levels has a direct impact on collagen production, leading to a noticeable acceleration in skin thinning and sagging. Estrogen is a key player in maintaining skin hydration, elasticity, and collagen synthesis, so its decline can feel like a sudden unwelcome shift in skin texture. Understanding these diverse factors is critical, because it allows us to adopt a multi-faceted approach to skin tightening, addressing not just the symptoms, but the root causes.

Foundational Lifestyle & At-Home Strategies for Firmer Skin

Okay, let’s shift gears from understanding the problem to actively tackling it. When we talk about tightening skin without surgery, it’s easy to immediately jump to the latest laser or fancy cream. But here’s the unvarnished truth: without a solid foundation of healthy lifestyle habits, even the most cutting-edge treatments will only offer temporary or suboptimal results. Think of it like trying to build a skyscraper on quicksand. You need a stable base. These foundational strategies aren't just "nice-to-haves"; they are the non-negotiable bedrock for genuinely supporting your skin's elasticity and overall health. They are accessible, often inexpensive, and surprisingly powerful when applied consistently. This is where the real, sustainable change begins, from the inside out.

I often tell people that the path to firmer skin isn't a sprint; it's a marathon, and these daily habits are your training regimen. They might not offer the instant gratification of a quick fix, but their cumulative effect is profound and long-lasting. We’re talking about nourishing your body, hydrating it, moving it, and giving it the rest it desperately needs to repair and regenerate. It’s a holistic approach, recognizing that your skin isn't an isolated organ but a vibrant, responsive part of your entire system. Embrace these strategies not as chores, but as acts of self-care that will pay dividends not just for your skin, but for your overall well-being. This is where you become an active participant in your skin's journey, taking back some control from the relentless march of time and environmental stressors.

The Power of Nutrition: Skin-Firming Foods and Supplements

You know that old adage, "you are what you eat"? Well, it holds profoundly true for your skin. What you put into your body has an incredibly direct impact on its ability to produce and maintain collagen and elastin, fight off damage, and ultimately, stay firm and resilient. This isn't about restrictive diets or chasing fads; it's about intelligent, intentional nourishment. Think of your plate as a toolbox, and each food item as a specific tool for skin repair and rejuvenation. Without the right tools, the construction project – your skin’s structure – simply can’t be completed effectively.

Let’s talk about the superstars of skin-firming nutrition. First up, Vitamin C. This isn’t just for warding off colds; it’s an absolute non-negotiable for collagen synthesis. It acts as a crucial co-factor, meaning your body literally cannot produce collagen without it. Beyond that, Vitamin C is a potent antioxidant, protecting your existing collagen and elastin from free radical damage. Citrus fruits, bell peppers, strawberries, and broccoli are fantastic sources. Then there's Vitamin E, another powerhouse antioxidant that works synergistically with Vitamin C to shield skin cells from oxidative stress. You'll find it in nuts, seeds, leafy greens, and vegetable oils. Don't forget Zinc, which plays a vital role in collagen synthesis and wound healing, making it essential for skin repair. Oysters, red meat, poultry, beans, and nuts are good sources.

Omega-3 fatty acids are also incredibly important. These healthy fats help maintain the integrity of your skin’s lipid barrier, locking in moisture and keeping skin plump and hydrated, which in turn makes it appear firmer. They also have anti-inflammatory properties, which can mitigate damage. Think fatty fish like salmon, mackerel, and sardines, as well as flaxseeds and walnuts. And, of course, we absolutely cannot overlook protein. Collagen itself is a protein, and your body needs a steady supply of amino acids (the building blocks of protein) to synthesize new collagen. Lean meats, poultry, fish, eggs, dairy, legumes, and quinoa are all excellent sources. Without adequate protein, your body simply doesn't have the raw materials to repair and rebuild.

Here’s a quick list of skin-firming food categories to prioritize:

  • Berries and Citrus Fruits: Rich in Vitamin C for collagen production and antioxidants.
  • Leafy Green Vegetables: Packed with antioxidants, vitamins, and minerals.
  • Fatty Fish (Salmon, Mackerel): Excellent source of Omega-3s and lean protein.
  • Nuts and Seeds (Almonds, Walnuts, Chia Seeds): Provide Vitamin E, Omega-3s, and healthy fats.
  • Bone Broth: Contains collagen, amino acids, and minerals that support skin health.
When it comes to supplements, while a balanced diet should always be your primary focus, certain supplements can offer a targeted boost. Collagen peptides (hydrolyzed collagen) are a popular choice, as they are easily digestible and provide the amino acids needed for collagen synthesis. Look for marine or bovine sources. I’ve seen people scoff at collagen supplements, but the science increasingly suggests they can indeed provide the building blocks your body needs, especially as natural production declines. Hyaluronic acid supplements can also help improve skin hydration and plumpness from within, indirectly contributing to a firmer appearance. Always consult with a healthcare professional before starting any new supplement regimen, especially if you have underlying health conditions. Remember, consistency is key; these aren't magic pills but supportive aids to a well-rounded strategy.

Hydration as a Cornerstone for Skin Elasticity

Let’s talk about water. Simple, unassuming water. We hear it all the time: "Drink more water!" But when it comes to skin health, and specifically skin elasticity and firmness, this isn’t just a feel-good platitude; it’s a profound truth. Think of your skin cells like tiny grapes. When they’re well-hydrated, they’re plump, firm, and resilient. When they’re dehydrated, they shrivel into raisins – losing their volume, becoming less elastic, and accentuating every fine line and wrinkle. It’s a visual that always sticks with me, and it perfectly illustrates the critical role of internal hydration.

Adequate water intake is the unsung hero of plump, resilient skin. It directly impacts the turgor pressure within your cells, which is essentially how "full" and firm they appear. When your body is properly hydrated, your skin cells are well-nourished and can perform their functions optimally, including collagen production and repair. Dehydration, even mild dehydration, can signal to your body to prioritize vital organ function over "less essential" processes like skin repair. This means slower cell turnover, reduced nutrient delivery to the skin, and a compromised ability to maintain its structural integrity. Your skin starts to look dull, feels rough, and most importantly for our discussion, loses its bounce and elasticity, making existing laxity appear more pronounced.

But it's not just about the cells themselves. Hydration is also crucial for maintaining the integrity of your skin's barrier function. The outermost layer of your skin, the stratum corneum, acts like a protective wall, preventing moisture loss and blocking environmental aggressors. This barrier relies on a delicate balance of lipids and water. When you're dehydrated, this barrier can become compromised, leading to increased transepidermal water loss (TEWL). This means moisture evaporates from your skin more easily, exacerbating dryness, flakiness, and a general lack of suppleness. A compromised barrier also makes your skin more vulnerable to external damage, further contributing to collagen and elastin breakdown.

Pro-Tip: The Hydration Test
Gently pinch the skin on the back of your hand. If it snaps back immediately, you're likely well-hydrated. If it takes a few seconds to return to normal, or if it tents up, you might be dehydrated. This simple test, while not perfectly scientific, can give you a quick indicator.

So, how much water is "adequate"? While individual needs vary based on activity level, climate, and overall health, a general guideline is to aim for around 8 glasses (roughly 2 liters) of water per day. But don't just chug it all at once; consistent sipping throughout the day is more effective for sustained hydration. Consider incorporating hydrating foods into your diet too, like cucumbers, watermelon, celery, and oranges, which contribute to your overall fluid intake. This isn't about a quick fix or a temporary boost; it's about establishing a consistent habit that supports your skin's fundamental health and, by extension, its elasticity and firmness over the long haul. Remember, topical moisturizers are fantastic for surface hydration, but true skin elasticity comes from within.

Targeted Exercises for Underlying Muscle Tone (Face & Body)

Now, this is where things get a little controversial, a bit nuanced, and frankly, quite interesting. When we talk about "tightening skin," our minds usually go straight to the skin itself. But what if I told you that strengthening the muscles beneath the skin could offer a subtle, yet noticeable, lifting effect? This isn't about magically erasing deep wrinkles or reversing severe sagging, but it's about providing a more toned, supportive foundation for your skin, particularly for the face and neck. Think of it as reinforcing the frame of a house; the walls might still be old, but a stronger frame can make them appear more stable.

For the body, this concept is more straightforward. Regular strength training builds muscle mass, which fills out the space beneath the skin. This can make the skin appear tighter and smoother, especially in areas like the arms (biceps and triceps), thighs, and abdomen. If you’ve experienced moderate weight loss, building muscle can help mitigate some of the resulting skin laxity by providing volume and shape. It’s about creating a firmer, more contoured silhouette that naturally pulls the skin tauter. This isn't a direct skin tightening mechanism, but rather an indirect one that improves the overall appearance of firmness and reduces the look of "loose" skin. It’s why consistent exercise is always part of a comprehensive body transformation plan.

The face, however, is where the debate often flares up. "Facial exercises" or "facial yoga" have gained popularity, promising to lift jowls, reduce neck sagging, and even smooth out wrinkles. Skeptics often argue that these exercises could actually cause more wrinkles by encouraging repetitive muscle movements. And they have a point. However, the proponents argue that by strengthening and toning the underlying facial muscles – the ones that atrophy and lose volume with age, much like body muscles – you can create a subtle, upward lift and improve facial contours. It's not about making exaggerated expressions, but about controlled, targeted movements that build muscle density.

Insider Note: The Facial Muscle Paradox
The key here is control. Excessive, uncontrolled facial movements (like squinting or frowning) can indeed create dynamic wrinkles that eventually become static. But targeted, isometric-like exercises, performed with awareness and gentle resistance, aim to build muscle volume and tone, which can provide a plumping effect. It’s about strengthening the muscles that lift (like the ones in your cheekbones) and support (like the platysma in the neck), rather than the ones that cause creasing.

Consider the platysma muscle in your neck, for example. It’s a broad, thin sheet of muscle that extends from your chest up to your jawline. As it weakens, it can contribute to the appearance of a "turkey neck" or prominent neck bands. Targeted exercises, like gently tilting your head back and pushing your tongue against the roof of your mouth, can help to strengthen and tone this muscle, providing a subtle tightening effect in the neck and jawline area. Similarly, exercises that engage the cheek muscles can help to lift and plump the mid-face, counteracting some of the gravitational pull.

Here are a few general principles for targeted facial exercises, if you choose to explore them:

  • Be Gentle and Deliberate: Avoid aggressive pulling or stretching of the skin. Focus on muscle contraction.
  • Consistency is Key: Like any muscle-building regimen, results come with regular, consistent practice, typically several times a week.
  • Focus on Lifting Muscles: Prioritize exercises that engage muscles responsible for upward and outward movements, rather than those that cause downward pull or creasing.
  • Combine with Skincare: These exercises are a supportive measure, not a standalone solution. They work best when combined with effective skincare and overall healthy habits.
Ultimately, while facial exercises won't give you surgical results, they can, for some, provide a noticeable improvement in muscle tone and contour, contributing to a firmer, more lifted appearance. It's a low-risk, no-cost option that, when approached thoughtfully, can be a valuable addition to your non-surgical toolkit. Just manage your expectations and listen to your body – and your face!

Quality Sleep and Stress Management for Skin Regeneration

If you’re anything like me, you’ve probably pulled an all-nighter or two in your life, only to wake up feeling like a zombie and looking like one too. The evidence is literally staring back at you in the mirror: dull skin, puffy eyes, accentuated lines. This isn't just a temporary phenomenon; chronic sleep deprivation and unmanaged stress are silent saboteurs of skin firmness and overall vitality. We often underestimate their power, but they are absolutely critical components in the complex symphony of skin regeneration and collagen synthesis. Ignoring them is like trying to grow a garden without water or sunlight – it just won't thrive.

Let’s talk about sleep first, because it’s truly when your skin goes into overdrive repair mode. While you’re dreaming, your body isn't just resting; it's actively working to repair the damage accumulated throughout the day. This is when growth hormone is released, which is vital for cellular repair and regeneration, including the production of new collagen. During deep sleep, blood flow to your skin increases, delivering essential nutrients and oxygen while simultaneously flushing away waste products. This process is often referred to as "beauty sleep" for a reason – it’s literally the time your skin rebuilds itself, replenishes its moisture barrier, and strengthens its structural components. Inadequate sleep disrupts this vital repair cycle, leading to a cascade of negative effects: reduced collagen production, impaired barrier function, increased inflammation, and a slower cell turnover rate. The result? Skin that looks tired, lacks firmness, and is more prone to sagging and premature aging.

Now, let’s tackle stress. Oh, stress, the modern epidemic that touches every facet of our lives, including our skin. When you're under chronic stress, your body releases a cocktail of hormones, most notably cortisol. While cortisol has essential functions, chronically elevated levels are detrimental to your skin. Cortisol breaks down collagen and elastin, accelerating the very process we’re trying to combat. It also increases inflammation throughout the body, which can further damage skin cells and hinder their repair mechanisms. Think of it: your body is in "fight or flight" mode, prioritizing immediate survival over long-term maintenance like skin health. This means fewer resources are allocated to collagen production and repair, and existing structures are more vulnerable to breakdown.

Pro-Tip: The Cortisol Connection
Chronic stress doesn't just make you feel older; it literally makes your skin age faster. High cortisol levels can also trigger breakouts, exacerbate conditions like eczema and psoriasis, and make your skin more sensitive and reactive. Managing stress isn't just for your mental health; it's a direct investment in your skin's future.

So, what can we do? Prioritizing quality sleep means aiming for 7-9 hours of uninterrupted rest each night. Establishing a consistent sleep schedule, creating a dark, cool, and quiet sleep environment, and winding down with relaxing activities before bed can all make a significant difference. For stress management, the strategies are as varied as people themselves. What works for one person might not work for another, but the key is finding something that helps you decompress. This could be mindfulness meditation, yoga, regular exercise, spending time in nature, pursuing a hobby, or simply setting boundaries and learning to say no. Both sleep and stress management are not luxuries; they are fundamental biological necessities that profoundly influence your skin's ability to repair, regenerate, and maintain its youthful firmness. Neglect them at your skin's peril.

Topical Solutions: Creams, Serums & Ingredients That Deliver Results

Alright, now we're venturing into the exciting world of what you can actually put on your skin to make a difference. After laying the groundwork with foundational lifestyle habits, topical solutions are your next powerful line of defense against skin laxity. Let's be clear: no cream or serum is going to deliver the dramatic, instant lift of a surgical procedure. If anyone promises that, run the other way. However, with consistent use and the right active ingredients, topical solutions can absolutely improve skin texture, boost collagen production, enhance elasticity, and visibly firm the skin over time. It’s about playing the long game with smart, scientifically backed formulations.

The sheer volume of products on the market can be overwhelming, a dizzying array of promises and ingredients. My goal here is to cut through the noise and focus on the heavy hitters, the ingredients that have robust scientific evidence supporting their efficacy in stimulating skin repair and promoting firmness. We're looking for ingredients that don't just sit on the surface, but actively communicate with your skin cells, encouraging them to behave like younger, healthier cells. This often involves stimulating collagen synthesis, protecting against degradation, or improving the skin's overall structural integrity. Remember, patience and consistency are your best friends here. Don't expect miracles overnight, but do expect noticeable improvements with diligent application.

Retinoids: The Gold Standard for Collagen Production

When it comes to topical ingredients that truly deliver on the promise of firmer, more youthful-looking skin, retinoids stand head and shoulders above the rest. I’m talking about the undisputed heavyweight champions, the gold standard, the ingredients that almost every dermatologist and skincare expert will recommend. If you're serious about skin tightening without surgery, incorporating a retinoid into your routine is not optional; it's essential. Their power lies in their ability to fundamentally change how your skin cells behave, literally signaling them to act younger.

So, what exactly are retinoids? They are a class of compounds derived from Vitamin A, and they come in various forms and strengths. The most potent and well-researched is tretinoin (often known by brand names like Retin-A), which is prescription-strength. Then there are over-the-counter options like retinol, retinaldehyde (or retinal), and retinyl palmitate, listed in decreasing order of potency. The magic happens when these retinoids convert into retinoic acid within the skin (tretinoin is retinoic acid, hence its direct potency). Once converted, retinoic acid binds to specific receptors in your skin cells, influencing gene expression and promoting a cascade of beneficial effects.

The primary reason retinoids are so revered for skin tightening is their remarkable ability to stimulate collagen production. They encourage fibroblasts (the cells responsible for producing collagen and elastin) to ramp up their activity, leading to an increase in new, healthy collagen fibers. This helps to thicken the dermis, improve skin density, and restore some of that lost structural support, which in turn leads to firmer, less lax skin. Beyond collagen, retinoids also accelerate cell turnover, meaning they help your skin shed old, damaged cells more quickly and replace them with
