Smile lines can make the face look tired even when you feel rested. These folds, which run from the sides of the nose toward the corners of the mouth, are a normal part of facial expression and aging. The best treatments for smile lines depend on why yours have become more noticeable – and the most natural-looking plan is rarely a one-size-fits-all solution.
At A Younger You Med Spa, we begin with a thoughtful conversation about what you see in the mirror, your skin history, and the level of change you want. Some clients want a subtle refresh before an event. Others are ready to address years of volume loss, sun damage, or skin laxity. Both goals deserve an honest, personalized recommendation.
Why Smile Lines Become More Visible
Smile lines are also called nasolabial folds. They form because the face moves, but they can deepen over time as collagen, elastin, and supportive facial fat naturally decrease. Sun exposure, smoking, genetics, weight changes, and dehydration may also affect how prominent they appear.
The key distinction is whether the lines are mostly dynamic or etched in at rest. If they appear mainly when you smile, muscle movement may be a major factor. If they remain visible when your face is relaxed, lost cheek support, thinning skin, and changes around the mouth are often contributing factors.
This matters because filling the fold itself is not always the best first step. In many cases, carefully restoring support in the cheeks or midface softens the fold more naturally than adding too much product directly into it.
Best Treatments for Smile Lines by Concern
Dermal fillers for volume loss and deeper folds
Hyaluronic acid dermal fillers are often one of the most effective nonsurgical options for moderate to deep smile lines. These injectable gels add support beneath the skin, helping soften a crease that has become more defined at rest. Results are visible right away, although final settling can take a little time.
For some clients, filler is placed directly in the nasolabial folds. For others, treatment begins higher in the cheeks to restore structural support and reduce the pull toward the center of the face. This approach can create a softer, less heavy result.
Filler is not a permanent treatment, and longevity varies by product, treatment area, metabolism, and amount used. Many people enjoy results for several months to more than a year. It is also a medical procedure, which is why choosing a qualified, experienced provider matters. Facial filler carries rare but serious risks, including vascular complications, and it should be performed by a trained medical professional who understands facial anatomy and proper response protocols.
Neuromodulators for expression-related lines
Neuromodulators, commonly known by brand names such as Botox, can relax specific muscles that repeatedly crease the skin. They are excellent for areas such as the forehead, frown lines, and crow’s feet. For smile lines, however, they are not usually the primary treatment.
The muscles around the mouth are essential for speech, smiling, and eating, so this area requires a conservative and highly individualized approach. In the right situation, a small amount of neuromodulator may help with nearby expression patterns, but it will not replace lost volume or erase a deep nasolabial fold. A consultation helps determine whether it belongs in your plan at all.
Microneedling and PRP for early lines and skin quality
When smile lines are fine, crepey, or paired with overall texture concerns, collagen-stimulating treatments can make a meaningful difference. Microneedling creates controlled microchannels in the skin to encourage collagen and elastin production. A series of treatments can improve texture, firmness, and the look of fine lines over time.
Platelet-rich plasma, or PRP, may be used alongside microneedling for clients seeking an added regenerative component. PRP is prepared from a small sample of your own blood and contains concentrated platelets and growth factors. It can support the skin’s natural repair response and is often chosen by clients who want gradual, refreshed-looking improvement.
These treatments do not create the instant volume of filler, and they cannot fully lift a deeply folded area. Their strength is improving the quality of the skin itself. For many clients, that makes them a valuable part of long-term facial rejuvenation.
Laser, IPL, and resurfacing for sun-related aging
If the skin around your smile lines has uneven tone, sun spots, redness, or roughness, laser and light-based treatments may help improve the overall appearance of the area. IPL can target certain types of pigmentation and redness, while laser resurfacing options can support collagen remodeling and smoother texture.
Chemical peels may also be appropriate for superficial texture and dullness. The right choice depends on your skin type, sensitivity, pigment history, and desired downtime. Clients with melasma, deeper skin tones, rosacea, or a history of post-inflammatory hyperpigmentation need especially careful treatment selection.
PDO threads for selected laxity concerns
For some people, mild to moderate skin laxity contributes to the appearance of heavier smile lines. PDO thread lifts can provide temporary support while stimulating collagen production. They may be considered when a client wants more lift than skincare or microneedling can provide but is not interested in surgery.
Threads are not the right fit for every face, and they do not replace the results of a surgical facelift. They also require realistic expectations and an evaluation of skin thickness, facial volume, and degree of laxity. When appropriate, they may be combined with other treatments for a more balanced result.
Why Combination Treatment Often Looks Most Natural
Smile lines rarely happen for just one reason. A client may have midface volume loss, fine lines around the mouth, pigment changes, and reduced collagen at the same time. Treating only one concern can help, but it may not create the balanced improvement they are hoping for.
A personalized plan might pair conservative cheek or fold filler with microneedling, PRP, professional skincare, or resurfacing treatments. This combination addresses both structure and skin quality. It also lets treatment be paced over time, which is ideal for clients who prefer subtle results rather than a dramatic change in one appointment.
What Skincare Can and Cannot Do
Consistent skincare supports every aesthetic treatment plan. Daily broad-spectrum sunscreen is one of the most practical ways to protect collagen and prevent lines from becoming more pronounced. Medical-grade products with retinoids, antioxidants, peptides, and hydrating ingredients may also improve skin texture and resilience over time.
Still, skincare has limits. A topical product cannot replace volume that has shifted or been lost beneath the skin. It can help maintain results and improve the surface of the skin, but deeper folds usually need an in-office treatment if your goal is visible correction.
Choosing a Treatment You Can Feel Good About
The right treatment should fit your facial anatomy, budget, comfort level, and timeline. If you have an important event next week, filler may offer faster visible improvement than collagen induction treatments. If you prefer gradual changes with little risk of looking overdone, a series of microneedling or laser treatments may be a better starting point.
Be open about previous injectables, dental work, medications, allergies, skin conditions, and whether you are pregnant or breastfeeding. These details help your provider recommend treatment safely. A good consultation should never feel rushed or pressured. You deserve clear information about benefits, downtime, cost, maintenance, and what a treatment realistically can and cannot accomplish.
Smile lines tell the story of a life full of expression, but you can still choose to soften the changes that no longer feel like you. The most flattering results preserve your ability to smile freely while helping your face look rested, supported, and like yourself.
