La Roche-Posay Effaclar K Moisturiser for Oily Skin

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.

This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": carnosine, sarcosine.

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).

This product contains carnosine. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works.

The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: capryloyl salicylic acid.
