Comparison of Glycolic Acid and Lactic Acid in Improving Pigmentation
Husband's skin pigmentation is plagued by many people. Today, discuss the effect of glycolic acid and lactic acid in this disease, in order to distinguish the advantages and disadvantages of the two.

Glycolic acid belongs to α-hydroxy acids, with small molecules and strong penetration. It can quickly dissolve the combination between keratin in the stratum corneum of the skin, and promote the shedding and renewal of keratinocytes. And it can increase the metabolism of the skin, make the distribution of melanin particles uniform, and then reduce pigmentation. However, it is more intense, and people with sensitive skin use it, or cause redness, tingling and other discomfort.

Lactic acid is also an alpha-hydroxy acid. Compared with glycolic acid, the molecule is slightly larger and milder. In the stratum corneum, it can moisturize and regulate the acid and alkali of the skin, create a suitable environment, and help melanin metabolism. Lactic acid can stimulate collagen production, tighten the skin, and improve pigmentation caused by aging the skin. Because of its mildness, it is suitable for a wider range of skin, and those with sensitive and weak skin can also try it.

If the skin has strong tolerance and wants to improve pigmentation efficiently, glycolic acid may be a good choice, and it can be used properly and quickly. However, the skin is sensitive and delicate, and if you want to gently recuperate, lactic acid is more suitable, and long-term use can also gradually show results. Therefore, the choice of glycolic acid or lactic acid depends on the characteristics of the individual skin and should not be followed blindly.
