Smile Lines: Can You Really Soften Them?

Hint: Prevention is everything.

Smile lines are often the first facial lines to make themselves known—and the hardest to ignore. They frame our expressions, mark moments of joy, and tell the story of a life well lived. Still, many of us wonder: can they actually be softened? The short answer is yes—but with realistic expectations and a smart, layered approach.

The Key Takeaways

• Smile lines—clinically known as nasolabial folds—form as facial volume decreases and skin elasticity shifts with age.

• Hyaluronic acid–based fillers can restore lost volume and visibly soften these lines with immediate, natural-looking results.

• Daily SPF is non-negotiable: sun damage accelerates collagen loss and deepens smile lines over time.

Why Smile Lines Appear in the First Place

Aging is inevitable—and, frankly, a privilege. But as the years go by, our skin undergoes structural changes. Collagen production slows, elasticity declines, and the skin’s natural glow begins to fade. Add decades of facial movement—smiling, laughing, talking—and it’s no surprise that fine lines eventually deepen into more noticeable folds.

Smile lines are among the most prominent. Alongside forehead lines and crow’s feet, they’re a natural result of expressive living. While they’re often worn as “badges of honour,” it’s completely normal to want to soften their appearance.

What Exactly Are Smile Lines?

“Smile lines” is the everyday term for nasolabial folds—the lines that run from the sides of the nose and curve around the mouth. They’re a normal part of facial anatomy and become more pronounced over time, particularly as the mid-face loses volume.

Because these lines are largely structural, they can be challenging to treat with skincare alone. That said, there are effective options—both in-clinic and at home.

What Causes Smile Lines to Deepen?

As we age, the face loses volume in very specific ways. The cheek area contains several fat pads that naturally descend and shift downward over time. As these fat compartments move, they settle around the nasolabial area, making smile lines appear deeper.

Certain lifestyle factors can speed up this process, including:

• Chronic sun exposure

• Rapid or significant weight loss

• Poor diet and dehydration

The Most Effective Ways to Treat Smile Lines

Hyaluronic Acid Fillers

For those seeking visible improvement, injectable fillers remain the gold standard. Hyaluronic acid—naturally present in the body—attracts and holds moisture, restoring volume and cushioning the skin. When placed strategically, fillers can soften smile lines while maintaining natural facial movement. It can offer a refreshed, natural look without invasive surgery. A solid skincare routine is essential for long-term maintenance.

PDO Threads

If you’re exploring alternatives to fillers, PDO (polydioxanone) threads offer a subtle lifting effect. These ultra-fine, medical-grade threads are inserted beneath the skin to gently reposition tissue and stimulate collagen production as they dissolve. Over time, this can improve firmness and soften nasolabial folds.

Radiofrequency Microneedling

This advanced treatment combines traditional microneedling with radiofrequency energy delivered deep into the dermis. The result? Enhanced collagen stimulation, skin tightening, refined pores, and improved elasticity—all of which help reduce the appearance of smile lines while keeping results natural.

Fraxel Laser Treatments

Fractional laser treatments like Fraxel 1550 work by creating microscopic injuries in the skin that trigger collagen remodeling. As the skin repairs itself, texture improves, fine lines soften, and new, healthier skin cells emerge—making this a popular option for addressing deeper smile lines.

What You Can Do at Home

Adopt a Targeted Skincare Routine

Look for formulas featuring retinoids, peptides, and collagen-supporting ingredients. While topical products won’t erase established smile lines, consistent use can improve skin elasticity and significantly slow their progression.

Make SPF a Daily Habit

Sunscreen is one of the most powerful anti-aging tools available. Daily SPF use protects collagen, prevents photoaging, and stops existing smile lines from deepening further.

Use Silicone Patches

For a temporary boost—think events or special occasions—silicone patches create an occlusive barrier that locks in hydration, instantly plumping the skin. Leave them on overnight (or at least eight hours) for best results.

Facial Massage

Gentle, regular facial massage increases circulation, reduces muscle tension, and offers short-term plumping benefits. While subtle, consistency can make a visible difference over time.

LED Light Therapy

Red LED light has been shown to stimulate collagen production and improve circulation. Whether via masks or handheld devices, regular use can help firm skin and soften fine smile lines.

Prescription Tretinoin

For long-term collagen repair, tretinoin is unmatched. This prescription-strength retinoid accelerates cell turnover and strengthens the skin’s collagen network—making it significantly more effective than over-the-counter retinol. Pair it with diligent moisturising to minimize irritation and maximize results.

The Bottom Line

Smile lines are a natural part of aging—but how they show up is something you can influence. While no topical product can erase them entirely, a combination of preventative skincare, sun protection, and in-clinic treatments can dramatically soften their appearance and keep skin looking smoother, firmer, and more resilient over time.

Because aging gracefully doesn’t mean doing nothing—it means doing what feels right for you.
