Anti-oxidationSide benefit · Carnosine, Aristotelia chilensis fruit extract + 2 moreWorks well
This product contains antioxidants (carnosine) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
MoisturizingSide benefit · Carnosine, Tephrosia purpurea seed extractWorks
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": carnosine.
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).
Anti-agingSide benefit · Carnosine, Ascorbic acidMay help
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.
