Anti-oxidationCamellia sinensis leaf extract, Caffeine + 2 moreMay help
This product contains antioxidants (camellia sinensis leaf extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
MoisturizingHyaluronic acid, Camellia sinensis leaf extract + 1 moreWorks
“Skin feels cool and calm as it’s infused with moisture while skin’s barrier is protected from damaging free radicals.”
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": hyaluronic acid, cucumis sativus fruit extract.
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).
