This is a great antioxidant serum for helping with signs of aging. It is supposed to target wrinkles, dullness, hyperpigmentation and discoloration. Really a good one for repairing damaged skin. It's key ingredients are coenzyme q10(antioxidant), matrixyl 3000(peptide), hyaluronic acid and vitamin E. You can use it daily, am or pm. I use mine in the am. It goes well underneath my makeup. It has a nice consistency, not real thin, and easy to spread. It isn't sticky and absorbs nicely. I've since repurchased and on my 2nd bottle. I've noticed my skin looking glowy, more plump and hydrated after applying. It's quite moisturizing. And zero fragrance. I think this may help improve your skin barrier too.
