Sunday Riley Good Genes All-in-One Lactic Acid Treatment (5ml / 0.17 fl oz)

Sunday Riley Good Genes All-in-One Lactic Acid Treatment (5ml / 0.17 fl oz) Brand: Sunday Riley “This exfoliating lactic acid treatment does it all: brightens, smooths, plumps, and evens out skin tone without irritation. Plus, it leaves your complexion glowy for the long run (making it the most aptly named product we know).” HOW TO USE Start by using twice a week, then work up to daily use, if needed. Apply a thin layer over clean skin and follow with a moisturizer. As with any lactic acid treatment, make sure to wear SPF to prevent sun sensitivity.
