Nasolabial folds aren’t entirely preventable because they’re partly structural, created by the way your facial muscles attach to skin every time you smile. But their depth and how early they become noticeable depend heavily on factors you can control: sun exposure, diet, sleep habits, weight stability, and how well you maintain your skin’s collagen supply. Most people start noticing these lines around age 30, and a combination of daily habits can meaningfully slow their progression.
Why These Folds Form in the First Place
Understanding the mechanics helps you target prevention effectively. Three things work together to create nasolabial folds, and they accelerate with age.
First, the fat pad that sits over your cheek is loosely connected to the tissue above the fold line. As the ligaments holding it in place lose resilience, that fat pad slides downward, creating a visible bulge above the crease. Second, the ligaments connecting your skin to the deeper structural layer of your face (called the SMAS) weaken over time, letting skin and fat sag. Third, and this is the part most people don’t realize, specific muscles that lift your upper lip attach directly to the skin along the nasolabial fold. Every time you smile, those attachment points pull the skin inward below the fold while pushing the fat layer above it outward. That repeated mechanical action deepens the crease over decades.
This means nasolabial folds aren’t purely an aging problem. They’re also a movement problem. You can’t stop smiling (nor should you), but you can address the other contributors: collagen loss, skin laxity, fat pad descent, and external forces that accelerate all three.
Protect and Rebuild Collagen
Collagen is the scaffolding that keeps skin firm enough to resist folding under mechanical stress. Two things destroy it fastest: UV radiation and the natural slowdown in production that begins in your mid-20s. Daily broad-spectrum sunscreen with at least SPF 30 is the single most effective anti-aging habit for any part of your face, nasolabial folds included. UV damage breaks down existing collagen fibers and impairs your skin’s ability to make new ones.
Topical retinoids are the best-studied tool for actively rebuilding dermal density. Retinoic acid increases the density of both the epidermis and the deeper dermis, and when combined with compounds that enhance its activity, one pilot study measured a 31% increase in epidermal density and a 12% increase in dermal density. Over-the-counter retinol works through the same pathway but converts to retinoic acid more slowly in the skin, so results take longer. Starting a retinoid in your late 20s or early 30s, before deep lines set in, gives you the most preventive benefit.
Vitamin C serums complement retinoids by neutralizing free radicals and serving as a required building block for collagen synthesis. Using vitamin C in the morning under sunscreen and a retinoid at night covers both sides of the equation: protecting existing collagen during the day and stimulating new production overnight.
Reduce Sugar and Glycation Damage
Glycation is a chemical reaction where sugars in your bloodstream bond permanently to collagen and elastin fibers, making them stiff and brittle. The resulting compounds, called advanced glycation end-products (AGEs), accumulate in skin starting in early life but produce visible symptoms around age 30. Once collagen fibers are cross-linked by glycation, they can’t be easily repaired, and the skin loses elasticity.
AGEs damage skin through multiple routes. They trigger inflammation, generate large amounts of free radicals that create oxidative stress, and deplete the body’s reserves of vitamin C, vitamin E, and glutathione. All of this disrupts normal collagen production in the dermis. The accumulation of AGEs also causes facial yellowing and dullness, compounding the aged appearance.
The most direct way to slow glycation is to reduce your intake of sugar and foods that spike blood glucose. High-sugar foods also activate reward circuits in the brain that drive cravings for more glucose-heavy foods, creating a cycle. Cooking methods matter too: grilling, frying, and broiling at high temperatures produce more dietary AGEs than steaming, boiling, or slow-cooking. A diet lower in refined carbohydrates and processed foods won’t reverse existing glycation, but it significantly slows new accumulation.
Keep Your Weight Stable
Rapid weight loss is one of the fastest ways to deepen nasolabial folds. Research on patients who underwent significant weight loss found that the midface region experienced the most dramatic volume change, characterized specifically by deep nasolabial folds and flattening of the cheekbones. The combination of fat loss and increased skin laxity mimics years of facial aging in a short period.
People over 40 are especially vulnerable. Older adults who have already experienced some natural facial aging find that major weight loss accelerates the process further, making them appear significantly older than before. This doesn’t mean you shouldn’t lose weight if you need to for health reasons, but losing weight gradually (one to two pounds per week) gives skin more time to adapt. Yo-yo dieting, where you repeatedly gain and lose significant weight, is particularly harmful because it stretches and deflates the facial fat pads repeatedly.
Change How You Sleep
Sleeping on your side or stomach presses your face into the pillow for hours every night, compressing the skin along your nasolabial folds. Research has documented that side sleeping contributes to specific facial deformities including nasolabial folds, lines around the mouth, and crow’s feet. Over years, this nightly mechanical pressure can etch lines into skin that has progressively less collagen to bounce back.
Sleeping on your back eliminates this compression entirely. If you can’t stay on your back all night, specialty pillows designed to cradle the head while keeping pressure off the cheeks and midface can help redistribute force away from wrinkle-prone areas. Silk or satin pillowcases create less friction than cotton but don’t address the underlying compression the way sleep position does.
Facial Exercises: Limited but Promising
Facial yoga programs specifically target the muscles around the nasolabial fold, particularly the orbicularis oris (around the mouth) and the zygomaticus minor (in the cheek). An eight-week clinical trial of middle-aged women found that a consistent face yoga routine (two supervised sessions plus five home sessions per week) increased muscle elasticity across all evaluated facial muscles. Muscle tone and stiffness in the mouth area decreased, meaning the muscles became more supple rather than chronically tense.
The catch: most studies in this area rely on subjective evaluations, and researchers note that more comprehensive, objective research is needed to confirm whether these muscle changes translate into visibly reduced folds. Face yoga is unlikely to cause harm and may offer modest benefits, but it shouldn’t be your primary prevention strategy. Think of it as a supplement to sun protection, retinoids, and dietary habits rather than a replacement.
Professional Options for Early Prevention
If you’re starting to notice faint lines and want to prevent them from becoming deep creases, a dermatologist can offer treatments that work on a structural level. Hyaluronic acid fillers injected into the midface (cheeks rather than the fold itself) can restore volume lost to early fat pad descent, supporting the tissue above the fold and reducing the shadow beneath it. This approach addresses the cause rather than just filling the crease.
Biostimulatory treatments that trigger your body’s own collagen production offer longer-lasting structural support, typically building results over several months. Microneedling and fractional laser treatments create controlled micro-injuries that stimulate collagen remodeling in the dermis, improving skin thickness and firmness over a series of sessions. These work best as preventive measures when folds are still shallow, rather than as corrections once deep creases have formed.
The most effective prevention combines daily habits with occasional professional treatments. Sunscreen, retinoids, stable weight, a lower-sugar diet, and back sleeping form the foundation. Professional interventions layer on top when early signs appear, slowing the transition from fine lines to entrenched folds.
