On the effect of glycolic acid on stretch marks
There are skin diseases in the world, and those with stretch marks trouble many women. Looking at glycolic acid today may be a good way to solve this dilemma.

Glycolic acid belongs to the family of fruit acids. Its molecules are tiny and can easily penetrate into the deep layers of the skin. In the process of skin metabolism, glycolic acid can promote the renewal of keratinocytes. For normal skin, the replacement of the stratum corneum is delayed, and the skin at stretch marks is more disordered. Glycolic acid can stimulate the division of underlying cells, accelerate the shedding of old keratin, and restore a uniform and smooth state to the surface of the skin, which also improves the appearance of stretch marks.

Furthermore, glycolic acid can stimulate collagen production. Stretch marks are mostly caused by the breakage and degeneration of elastic fibers and collagen in the skin. Glycolic acid acts on fibroblasts to promote the synthesis of more collagen and elastic fibers. Over time, the skin's elasticity gradually recovers, and stretch marks may be reduced.

However, it is not entirely dependent on its effect. Individual skin differences are quite large. Some people use glycolic acid, stretch marks are significantly lightened, skin tone is uniform, and lines are lighter; some people have little effect. Because of different skin types, dry, oily, and sensitive skin have different tolerances to glycolic acid. Sensitive skin may be difficult to withstand its irritation, and improper use can cause skin redness, swelling, and tingling.

And glycolic acid needs to be used properly. Concentration and frequency need to be cautious. Choose low-concentration products for initial use, and wait for the skin to adapt, and then increase as appropriate. The frequency of use should also be moderate, and too often can easily damage the skin barrier.

In summary, glycolic acid may be effective in stretch marks, but it is not a panacea. Those who want to remove stretch marks should use it cautiously according to their own skin type, or combine other methods for better effect.
