On the effect of glycolic acid on fine lines
There are various opinions on the effect of glycolic acid on fine lines. However, in its essence, glycolic acid has unique properties and can help improve the state of fine lines.

Glycolic acid belongs to the class of fruit acids and has strong permeability. It acts on the skin and can gently peel off the aging stratum corneum on the surface. If the stratum corneum accumulates for a long time, the skin is often rough and dull, and fine lines are easy to breed. Glycolic acid removes this obstacle, making the surface of the skin smooth again, and the appearance of fine lines is reduced.

Furthermore, glycolic acid can stimulate the metabolism of the skin. The metabolism of the skin is slow, the replacement of new cells is slow, and fine lines are easy to appear. Glycolic acid can stimulate cell vitality, accelerate the generation of new cells, fill the skin gullies caused by aging, and lighten fine lines.

And glycolic acid can promote collagen synthesis. Collagen is a key support for skin elasticity, and its content is reduced, the skin is loose, and fine lines are plagued. Glycolic acid can activate relevant mechanisms, increase collagen production, enhance skin firmness, and fundamentally relieve fine lines.

However, it is also prudent to use glycolic acid. Because it has a certain irritation, if the concentration is too high or used improperly, it will hurt the skin. Beginners should start at a low concentration and gradually check the tolerance of the skin. When using, pay attention to sun protection to prevent skin sensitivity.

In summary, glycolic acid is indeed beneficial to fine lines, but it can be used reasonably and moderately to obtain its benefits and avoid its harm, so that the skin can regain its youthful luster.
