Whether they appear early or deepen over time, smile lines are among the first visible marks on the face. Located around the mouth, they appear due to repeated facial expressions, but also under the effect of sagging skin or dehydrated skin.
Understanding the origin of smile lines and why they appear
Smile lines, also called nasolabial folds or nasolabial folds, form naturally between the sides of the nose and the corners of the mouth. Contrary to popular belief, they are not only linked to age: they can appear as early as the twenties, particularly in very expressive faces or thin skin.
Over time, these lines become more pronounced under the combined effect of several factors: the loss of collagen, a decline in skin elasticity, the melting of subcutaneous volumes, but also the central role of facial movements. Smiles, laughter, grimaces… the skin wrinkles, again and again, until it leaves a more lasting mark. Exposure to the sun, dehydration or even certain sleeping positions can also increase their visibility.
Retinol, peptides, hyaluronic acid: three active ingredients to target wrinkles without injections
Rather than resorting to invasive solutions, certain well-chosen cosmetic active ingredients can act on the surface and in depth to visibly fade smile lines. This is the case for retinol, peptides and hyaluronic acid, used in treatments formulated for their effectiveness on skin tone.
Retinol is a vitamin A derivative known to stimulate collagen production and accelerate cell renewal. In a gentle version, as in eye contour creams, it is particularly suitable for fine and sensitive areas around the mouth.
Peptides, for their part, are protein fragments capable of sending signals to the skin to promote firmness. When applied regularly, they help firm the skin tissues while providing lasting hydration.
Finally, hyaluronic acid remains an essential part of anti-wrinkle care. Present naturally in the skin, it retains water and plumps marked areas. Used in serum form, it acts quickly, visibly smoothing fine lines.
Three treatments tested and recommended for their targeted action on smile lines
These three treatments contain the active ingredients mentioned above – retinol, peptides, hyaluronic acid – in formulas designed for daily application. Without an abrasive or aggressive active effect, they can be easily integrated into a facial routine, even for sensitive skin.
ROC – Retinol Correxion Smoothing eye contour treatment
This fragrance-free treatment is formulated with pure retinol and a mineral complex to visibly improve the appearance of wrinkles, including on fine areas. Specially designed for the eye area, it is also suitable for the mouth area thanks to its light texture and skin tolerance.
The Ordinary – Hyaluronic Acid 2% + B5 (with Ceramides)
This serum concentrated in hyaluronic acid of different molecular weights acts on the surface as well as in depth to plump the skin. Enriched with provitamin B5 and ceramides, it intensely hydrates while strengthening the skin barrier.
Paula’s Choice – Pro-Collagen Peptide Plumping Moisturizer
This moisturizer combines pro-collagen peptides with amino acids and hyaluronic acid to strengthen skin structure and improve firmness. Its rich but non-greasy texture penetrates quickly and leaves the skin soft, supple and visibly smoother.

Yes, certain facial massage or yoga gestures can stimulate circulation and relax the muscles responsible for wrinkles, provided they are regular.

Not necessarily, but some foundations or powders that are too thick can accentuate creases. It is better to favor light and hydrating textures.
