Definitive Retinol Serum

Definitive Retinol Serum is a sophisticated overnight radiance treatment designed to resurface, brighten, and refine the complexion—without compromising comfort. This advanced formula combines encapsulated retinol suspended in a lipid (fat) delivery system, Bakuchiol, AHAs, ceramides, and multi-weight hyaluronic acids to deliver powerful results with remarkable gentleness.

Upon application, the encapsulated retinol melts into the skin, releasing Vitamin A more slowly and evenly for enhanced stability, deeper penetration, and significantly reduced irritation. Bakuchiol and Kahai Oil (a natural source of retinoids and fatty acids) reinforce the benefits of retinol while soothing and strengthening the skin.

A carefully balanced treatment of glycolic acid, antioxidants, barrier-repair lipids, and hydration complexes accelerates cellular turnover, smooths texture, reduces fine lines, brightens tone, and supports long-term regeneration. Overnight, the skin emerges refreshed, renewed, and noticeably more luminous.
