Reduces fine lines, wrinkles, and smooths texture without irritation. A two-step serum where powdered 0.25% Retinol is activated fresh in your palm by a moisturizing Hyaluronic Acid serum. This is both the perfect beginner and the perfect advanced Retinol. Retinol is the tried and true anti-aging ingredient but at effective levels, it's often harsh and irritating. As a powder, our Retinol stays potent but also pure with no nasty stabilizers needed. The result? A highly effective Retinol that's non-irritating. Clinically shown to reduce fine lines, wrinkles, and to smooth texture in 1–2 weeks. Subjects were screened for sensitive skin and used Time Rewind every night with no irritation, no tolerance build up needed.
