Beauty of Joseon Light On Serum : Centella + Vita C

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.

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

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).

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: ascorbic acid polypeptide, panthenol

This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains adenosine.

These ingredients in the product can also be helpful, even though there is less evidence for their effectiveness: ascorbic acid polypeptide, centella asiatica extract.

Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

This product contains antioxidants (3-o-ethyl ascorbic acid, ascorbic acid polypeptide, centella asiatica 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.
