How to Reduce and Prevent Smile Lines: Expert Dermatologist Tips
Learn expert-approved treatments and routines to minimize, prevent, and smooth out smile lines for youthful, radiant skin.
Smile lines—also called laugh lines or nasolabial folds—are one of the most common visible signs of facial aging. As natural as these lines are, many seek ways to minimize or prevent them for smoother, younger-looking skin. Fortunately, dermatologists offer a variety of effective strategies, from lifestyle changes and targeted skincare to professional in-office treatments. This guide synthesizes expert opinions and research to provide a comprehensive understanding of smile lines and the best options for addressing them.
What Are Smile Lines?
Smile lines, also known as nasolabial folds, refer to the creases that extend from the sides of the nose down toward the corners of the mouth. According to Dr. Karan Lal, a double board-certified dermatologist, these lines are most noticeable during facial expressions in youth but may become permanent as facial fat shifts, skin thins, and the face undergoes natural bony changes with age. Smile lines are considered dynamic wrinkles—they become more pronounced with repeated movement, such as laughing or smiling, but eventually settle in permanently as static lines over time.
While smile lines are a hallmark of natural aging and joyful expression, their deepening may be accelerated by factors such as sun exposure, genetics, and lifestyle habits.
Key Causes of Smile Lines
- Repetitive facial movements (smiling, laughing, talking)
- Loss of collagen and skin elasticity
- Fat loss in the cheeks and midface
- Thinning skin and bone resorption with age
- Sun exposure and UV damage
- Genetics and ethnicity
- Lifestyle choices (e.g., smoking, poor diet)
Top Expert-Backed Treatments for Smile Lines
Experts emphasize a combination of at-home skincare, lifestyle habits, and professional treatments—choosing what’s right depends on your age, skin type, and the depth of your lines.
1. Use Retinoids
Retinoids (prescription retinoic acid or over-the-counter retinol) are considered a gold standard for wrinkle prevention and treatment. They work by boosting collagen production, accelerating cell turnover, and smoothing fine lines. Dr. Joshua Zeichner recommends retinol-based products for gradual improvement in skin texture and firmness. Consistent use helps fade fine lines over time, though retinoids can cause dryness and irritation initially.
- Start with a low concentration and gradually increase as tolerated.
- Apply at night; use sunscreen during the day, as retinoids increase sun sensitivity.
2. Peptide-Based Skincare
Peptides are short chains of amino acids that send signals to skin cells to promote collagen and elastin synthesis. They’re a gentler yet effective alternative to retinoids for those with sensitive skin. According to dermatologists, peptide serums and creams hydrate and plump the skin, leading to a firmer appearance and smoothing out mild to moderate lines. Products like StriVectin High Potency Wrinkle Filler and Drmtlgy Needle-less Serum are highlighted by experts for their efficacy.
- Ideal for daily use, morning or night, especially for those not tolerating retinoids.
- Often combined with other anti-aging ingredients such as ceramides and niacinamide for barrier support.
3. Incorporate Hyaluronic Acid
Hyaluronic acid is a molecule that draws and retains moisture in the skin, resulting in plumper, dewier skin and temporarily minimizing the depth of lines. Many anti-aging moisturizers and serums contain hyaluronic acid, making them an easy addition to a daily routine.
- Pat or press hyaluronic acid serums onto damp skin, followed by a moisturizer.
- Ideal for all skin types, especially dehydrated or mature skin.
4. Prioritize Sun Protection
Regular use of broad-spectrum sunscreen (SPF 30 or higher) is singled out as the most crucial preventative step. Dermatologists stress that UV exposure is a leading cause of collagen breakdown, skin thinning, and premature wrinkling—including smile lines. Apply sunscreen every morning and reapply throughout the day, even on cloudy days or indoors if exposed to windows.
What others are reading
- Look for sunscreens with added antioxidants for extra defense.
- Consider makeup or moisturizers with built-in SPF for convenience, but don’t rely solely on them for complete protection.
5. Moisturize Consistently
Daily moisturizing helps maintain skin plumpness and elasticity, reducing the visible depth of lines. Choose creams rich in ceramides, glycerin, and hyaluronic acid, or opt for targeted anti-aging formulas containing peptides and antioxidants.
- Apply right after cleansing to lock in hydration.
- Night creams can be thicker for extra moisture overnight.
6. Professional Treatments for Stubborn Smile Lines
For established or deep smile lines, dermatologists may recommend in-office procedures that deliver more rapid and dramatic results. Consultation with a board-certified dermatologist or plastic surgeon is essential for these approaches.
| Treatment | Description | Best For |
|---|---|---|
| Injectables (Botox, Xeomin, Dysport, Jeuveau) | Temporarily relax facial muscles to soften dynamic wrinkles caused by movement. | Early or moderate lines, younger patients, prevention |
| Dermal Fillers (Hyaluronic Acid) | Fill in volume loss in the nasolabial folds, immediately smoothing deeper creases. | Moderate to deep lines, age-related volume loss |
| Laser Resurfacing (Fractional, CO2, Er:YAG) | Boosts collagen via targeted injury; smooths texture and refines wrinkles. | Texture improvement, all wrinkle depths |
| Microneedling | Creates micro-injuries to stimulate collagen; enhances skin smoothness naturally over time. | Fine to moderate lines, maintenance |
| Chemical Peels | Exfoliates top layers, revealing fresher, tighter skin and diminishing signs of aging. | Early lines, overall skin renewal |
- Note: In-office treatments yield the most dramatic and lasting results but may require maintenance and carry some downtime or risks. Always seek an experienced provider.
Natural Ways to Prevent Smile Lines
Beyond professional treatments and high-tech skincare, simple habits and daily choices make a significant impact on the prevention and progression of smile lines.
- Stay Hydrated: Drink plenty of water throughout the day to maintain skin moisture and plumpness.
- Eat an Antioxidant-Rich Diet: Foods high in vitamins A, C, and E support collagen synthesis and skin repair, guarding against environmental damage.
- Avoid Smoking and Alcohol: Both dehydrate the skin and accelerate aging processes, leading to early and deeper wrinkle formation.
- Sleep on Your Back: This minimizes facial compression and the formation of persistent sleep lines that may deepen over time.
- Manage Stress: Chronic stress can trigger inflammatory responses that hasten skin aging.
- Adopt a Consistent Skincare Routine: Gentle cleansing, regular moisturizing, and the periodic use of masks or exfoliants keep the skin resilient and healthy.
Shopping for Skincare: Key Ingredients to Look For
When selecting over-the-counter products to combat smile lines, dermatologists recommend prioritizing ingredients scientifically proven to support skin structure and regeneration.
- Retinol and Retinoids: For boosting collagen and resurfacing skin
- Peptides: For signaling skin to build new collagen and elastin
- Hyaluronic Acid: For deep hydration and immediate plumping
- Vitamin C: For brightening and supporting collagen formation
- Niacinamide: For strengthening the skin barrier and evening tone
- Ceramides: For sealing in moisture and supporting barrier function
- SPF: For daily, year-round sun protection
Consistent use over several weeks to months is essential for visible improvement; patience and regular application pay off in softer, smoother skin.
