K-Secret Seoul 1988 Retinal Liposome Eye Cream 4% is a high-potency anti-aging eye treatment featuring an impressive 4% retinal concentration encapsulated in advanced liposome delivery technology for maximum penetration and efficacy in the delicate periorbital area. Retinal, the most potent form of vitamin A available without a prescription, converts directly into retinoic acid within the skin, delivering faster and more dramatic anti-aging results than retinol including accelerated collagen production, rapid cellular turnover, and visible reduction of deep wrinkles, crow's feet, and crepey texture around the eyes. The liposome encapsulation system gradually releases retinal into the skin over time, minimizing the irritation, redness, and peeling typically associated with such high concentrations while ensuring sustained activity throughout the night. Additional hydrating and soothing ingredients buffer the potent retinal delivery, keeping the thin eye area comfortable, moisturized, and protected during the intensive renewal process.
