Whitening: Lactic acid has a whitening effect, can inhibit the activity of melanin, and has the effect of fruit acid peeling. In addition, it is much less irritating to the skin than glycolic acid. Therefore, using lactic acid for whitening is quite a good one. choose. In terms of open-shelf products, L’Oreal and Pond’s have some good products.
Moisturizing: Because lactic acid is a component of the natural moisturizing factor NMF in the skin, moisturizing is an important use of lactic acid in cosmetics. Generally, the neutralized lactic acid is used as a moisturizing ingredient, but unfortunately, this good moisturizing ingredient is also used by some large companies such as Johnson & Johnson, while some domestic companies use it for various reasons (the specific reasons will be written later). Some flashy, expensive moisturizing ingredients.
