Analysis of whether glycolic acid can dilute dark spots
The person with dark spots is the disease of the skin and the beauty of the face. Glycolic acid has attracted much attention in the field of skin care, and whether it can dilute dark spots is of concern to everyone.

Glycolic acid belongs to the family of fruit acids, with small molecules and strong power to penetrate the skin. The principle of diluting dark spots is based on several ends. First, glycolic acid can promote the renewal of stratum corneum cells, which makes the old cells on the surface of the skin quickly separate, and new cells grow rapidly. The formation of dark spots is often due to the accumulation of melanin in the epidermis and the acceleration of stratum corneum renewal. Melanin falls off with the old cells, and the color of dark spots gradually fades. Second, glycolic acid can inhibit the activity of tyrosinase. Tyrosinase is also a key enzyme in melanin synthesis. The activity of enzymes is inhibited, the production of melanin is reduced, and the color of dark spots also becomes lighter.

However, glycolic acid is used to dilute dark spots, and there are also its taboos. When used properly, the effect can be obvious; when used improperly, it will cause skin damage. Its concentration needs to be carefully selected. Although high-concentration glycolic acid has a strong power to dilute dark spots, it is also highly irritating, prone to skin redness, swelling, tingling, desquamation and other diseases, especially suitable for well-tolerated skin. Low concentrations have little irritation, but the effect of diluting dark spots may be slow, and it is suitable for sensitive skin. And when using it, you need to try it step by step, first try a small amount, and observe the skin's reaction. The dosage can be gradually increased without discomfort.

Furthermore, during the use of glycolic acid, sun protection is indispensable. After covering the skin with glycolic acid, the resistance to ultraviolet rays is reduced. If there is no sun protection, ultraviolet rays can easily stimulate melanin cells, causing more melanin production. Dark spots are not only not light, but there is a risk of aggravation.

To sum up, glycolic acid does have the potential to dilute dark spots. However, when using it, when carefully observing the characteristics of the skin, observing the norms of use, and complemented by comprehensive sun protection, it may achieve the purpose of diluting dark spots and beautifying the skin.
