Glycolic Acid and Lactic Acid in the Treatment of Peridermal Keratosis
Peridermal Keratosis is quite common and affects the appearance and touch of the skin. Glycolic acid and lactic acid play a significant role in their treatment. The following are the characteristics and efficacy of the two.

Glycolic acid is an alpha-hydroxy acid with small molecules and strong penetration. It can accelerate the metabolism of keratinocytes, peel off and accumulate keratin, smooth the mouth of hair follicles, and improve the symptoms of rough and papular keratosis. It can also stimulate collagen production, making the skin firmer and smoother. Many clinical practices have shown that glycolic acid has a good effect on mild to moderate peridermal keratosis. Long-term regular use of skin care products containing glycolic acid can gradually relieve symptoms and significantly improve the texture of the skin.

Lactic acid is also an alpha-hydroxy acid, which has moisturizing properties. It can increase the moisture content of the skin and make the skin soft. At the same time, lactic acid can gently exfoliate and reduce hair follicle blockage. For periceratosis, lactic acid has a good effect on improving dry and rough skin. Due to its relatively mild nature, it is suitable for sensitive skin with periceratosis.

In contrast, glycolic acid has strong effect and significant exfoliation effect. It is more suitable for skin with severe symptoms and good tolerance. Lactic acid gently moisturizes and is friendly to light symptoms and sensitive skin. When choosing, it depends on individual skin conditions. If it is oily, well tolerated and has severe symptoms of peri-hairy keratosis, glycolic acid may be preferred; if the skin is sensitive and the symptoms are mild, lactic acid is more suitable.

To treat peri-hairy keratosis, choose glycolic acid or lactic acid, should be combined with your own skin type and condition, or under the guidance of professionals, in order to achieve the best treatment effect and improve skin condition.
