Anti-agingAscorbic acidStrong evidence
“Complexion is evened out and more luminous while wrinkles are reduced.”
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains ascorbic acid.
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.
MoisturizingGlycerin, Biosaccharide gum-1 + 7 moreGood evidence
“Combines 10% pure Vitamin C in its most effective form, with Hyaluronic Acid and Vitamin E for hydration for a visibly plumper look.”
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
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. The following ingredients in this product do the job:
biosaccharide gum-1, glycerin.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethicone, c12-15 alkyl benzoate.
Anti-oxidationNot advertised by the brand · Ascorbic acid, Tocopheryl acetateStrong evidence
This product contains antioxidants (ascorbic acid) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
Evens skin toneNot advertised by the brand · Ascorbic acidStrong evidence
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: ascorbic acid.
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
