When dullness inevitably creeps in, fend it off with a cocktail of brightening and pigmentation-fighting plant extracts and antioxidants. With vitamin C (one of the most well-researched and proven ingredients in brightening and anti-aging skincare), licorice root and palmaria palmata extracts (skin-lightening agents that inhibit pigmentation), and niacinamide (a form of vitamin B3 that reduces the appearance of discoloration), uneven skin tone can become a thing of the past. This lightweight, never-tacky serum also helps firm, hydrate, and strengthen skin—those brightening ingredients have some solid fringe benefits.
