DL-Mandelic acid Use

1. DL-Mandelic acid is a kind of alpha hydroxy acid fruit acid with lipophilicity. Compared with common fruit acid-glycolic acid, mandelic acid has certain antibacterial ability. At the same time, compared with the common glycolic acid and lactic acid, the penetration speed of mandelic acid may be slower, which means that the irritation is less than that of glycolic acid. Its fat solubility is increased, and the stratum corneum permeation ability is improved.

2. Therefore, in the cosmetics industry, DL-Mandelic acid also has the function of dredging the oil in the pores and removing acne. Like glycolic acid and lactic acid, mandelic acid also has a certain whitening effect.

3. DL-Mandelic acid ingredients are suitable for dry skin, firm skin, non-pigmented skin, wrinkled skin, tolerant skin, pigmented skin, oily skin, these 7 types of skin.
