Cosmetic chemists Victoria Fu and Gloria Lu love this budget-friendly serum that features a 10 percent glycolic acid formula for a fraction of the price of most serums.
"This serum has an impressive level of niacinamide along with ascorbyl glucoside and green tea antioxidant, which can help tackle those pesky dark spots," says Fu and Lu.
Although this facial serum is a bit of a splurge, Fu and Lu like that it contains a 12 percent alpha hydroxy acid cocktail blend of glycolic, lactic, tartaric and malic acids, which can help revitalize damaged skin.
