Evens skin tone3-o-ethyl ascorbic acid, Ascorbic acidMay help
“The antioxidant formula brightens and evens skin tone while reducing signs of aging and tackling redness as well as post inflammatory spots and scars.”
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: 3-o-ethyl ascorbic acid.
MoisturizingBetaine, Polyglycerin-3 + 7 moreWorks
This product contains good ingredients to attract water to the upper layer of the skin. These ingredients are called "humectants": betaine, diglycerin.
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).

Ingredient callouts
- This product also contains Vitamin C (Ascorbic Acid) 3.50% - 5.30% It can be helpful in stimulating collagen production, neutralizing free radicals in skin and improving pigmentation marks. We recommend to use up this product quickly after opening: Ascorbic Acid degrades fast when it gets in contact with air and light. The moment the product turns orange, it is a sign that a significant share of the vitamin C in it is no longer effective.
- Humectants (glycerin 0.20% - 0.75%, diglycerin 0.55% - 1.35%, hyaluronic acid 1.20% - 1.80%, sodium hyaluronate 1.40% - 2.10%, polyglycerin-3 1.70% - 2.50% and betaine 2.50% - 3.80%). These ingredients help attract water to the upper layer of the skin and improve the skin hydration.
