The KSECRET Seoul 1988 Retinal Serum combines the power of 2% Retinal Liposome with the revitalizing properties of Black Ginseng Extract to deliver a high-performance anti-aging treatment for all skin types. This potent yet Gentle formula accelerates cell turnover, reduces fine lines, smooths uneven texture, and revives dull, tired-looking skin. Encapsulated retinal ensures deep penetration and stability with less irritation, while black ginseng helps energize and firm the skin with rich antioxidants. Enhanced with Niacinamide, Panthenol, and Beta-Glucan, this serum hydrates and brightens, leaving the skin visibly smoother and healthier. Ideal for night-time use, this serum targets signs of aging and environmental stress with a soft, fast-absorbing texture. How to Use After cleansing and toning, apply a few drops of the serum evenly to the face and neck. Gently pat until absorbed. Use in the evening, followed by a moisturizer. Always apply sunscreen the next morning, as retinal increases sun sensitivity.
