R+F Multi-Acid Enzyme Peel Dermatologist-created serum-like exfoliant that works smarter, not harsher. Removes dead skin cells 5X faster* for less visible dark spots, brighter, more even skin. What it is: A tone-evening, brilliance-boosting, dark spot-diminishing exfoliant packed in a luxurious lightweight serum. Goes beyond the surface to not only help remove dead skin cells, but also visibly fade the appearance of dark spots for glassy-looking skin. Made for all skin types, especially melanin-rich skin. 100% felt it was comfortable after application and noticed more even-looking skin tone after 8 weeks.
