Dry and/or mature skin needs regular exfoliation, but it's important not to overdo it. Our Hydrating Brightening Solution exfoliates with a combination of lactic acid and gluconolactone, because the molecules are larger and less likely to irritate skin. We balance the effects of the acids with niacinamide and seaweed extract to re-mineralize and support natural skin barrier. Then, a blend of naturally vitamin C rich mulberry and kakadu plum extracts boosts the brightening effects of lactic acid while also helping reduce the appearance of dark spots.
