The Hydration Helper

Created by a derm and with a you-will-see-it-working-in-less-than-two-weeks window to boot, MD Complete Anti-Aging Advanced Wrinkle Remover contains pure retinol, peptides and collagen-boosting vitamin C—a highly potent and supremely hydrating mix that you can feel.

What makes it different: The company warns that you might experience some skin flaking with this (almost akin to a mild peel), a sign that you know the product is going to work on cell turnover.
