They say everything is clearer in retrospect, but the skin-saving power of keratin has never been more obvious to us. Retrospect connected the dots over a decade ago, uncovering the link between keratin—a protein found naturally in our bodies—and skin’s ability to heal itself. Founded on more than 15 years of clinical research, the high-tech line uses a patented form of the protein, Replicine™ Functional Keratin©. The science-backed formulas go straight to work repairing a lifetime of damage and bolstering skin’s natural defenses, leading to a healthier—and younger-looking—complexion.
