The K-Secret Seoul 1988 Serum: Retinal Liposome 2% + Black Ginseng is a high-performance anti-aging serum designed to renew skin texture and reduce the appearance of fine lines and wrinkles. It is specifically formulated to be effective yet gentle, making it suitable for all skin types, including sensitive and mature skin.Retinal Liposome (2%): This "next-generation" form of Vitamin A converts to its active state up to 11 times faster than traditional retinol. The liposome encapsulation ensures deeper absorption and significantly minimizes the irritation often associated with retinoids.

Black Ginseng Extract (58%): A powerful antioxidant that provides anti-inflammatory benefits, boosts collagen production, and protects the skin from environmental stressors.

Retinal Boosting Complex: Includes Bakuchiol (a plant-based retinol alternative), Vitamin C, and 3 Peptides to further support skin elasticity and firmness while brightening the complexion.

Niacinamide & Adenosine: Work to refine pores, soothe the skin, and improve the moisture barrier.

Application: Apply a pea-sized amount to the face and neck after cleansing and toning.
Frequency: Start by using it 2 times a week for the first 1–2 weeks to build tolerance, then gradually increase to nightly use as skin adjusts.
Timing: Use only in your nighttime routine. If used during the day, following up with a broad-spectrum sunscreen is mandatory as retinal increases sun sensitivity.
