As skin cells turn over at a slower rate, dry cells are left to sit on skin's surface for longer periods of time, resulting in a lackluster and ashy complexion. But a scrub made with papaya (its alpha hydroxy acids gently dissolve dead cells), sugar (its granules exfoliate skin) and olive oil (its squalene hydrates) will instantly restore skin's youthful glow. We love this luxurious Papaya Facial Mask. (Buy from Facial Lounge, $76).
