Works for
ExfoliationCapryloyl salicylic acidWorks well
“Lipo-Hydroxy Acid is a derivative of salicylic acid, and has exfoliating and skin surface renewing properties”
This product can help exfoliate the skin. In other words, it helps break down the bonds between dead cells on the surface of the skin and speed up the skin turnover. Skin often appears softer and brighter after exfoliation, but overdoing it can result in disrupted skin barrier. The following ingredient is doing the exfoliating job in this product: capryloyl salicylic acid.
MoisturizingIsostearyl alcohol, Glycerin + 1 moreWorks
“Glycerin helps hydrate skin by absorbing water from the surrounding environment”
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": glycerin.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from within deeper layers of the skin. If the air is dry, humectants can speed up the moisture loss from the skin. This is why it is a good idea to use another product on top of this one to help "seal in" the moisture (look for ingredients like dimethicone, squalane, oils and butters).
