We're huge fans of Sunday Riley's entire skincare line, and this clarifying, line smoothing lactic acid treatment might just be our number-one pick. It's loaded with purified grade lactic acid that exfoliates dull, pore-clogging dead skin cells and it gives us younger-looking skin almost instantly — it's a true winner in our book.
Created by board-certified dermatologist and healthy aging expert Dr. Nicholas Perricone, this serum erases fine lines with retinol (and it doesn't cause any annoying irritation).
