K-Secret Seoul 1988 Serum

Contains 2% Retinal Liposome and Black Ginseng. It is an anti-aging serum designed to reduce wrinkles, improve skin texture and firmness, and reduce pigmentation and dark spots, giving a more even and radiant complexion. It is considered a beginner-friendly retinal product due to its gentle formulation.
How to Use
Frequency: Use in the nighttime skincare routine, as retinal can be deactivated by sunlight. It is recommended to start slowly (e.g., twice a week for the first two weeks) to build skin tolerance.
Application: After cleansing and toning, apply a pea-sized amount to dry skin. Applying on damp skin may cause irritation.
Method: Gently massage the serum until fully absorbed. Follow with a moisturizer; for sensitive skin, the “sandwich method” (moisturizer before and after the serum) is recommended.
Sun Protection: If used during the daytime, it must be covered by a broad-spectrum SPF 30+ sunscreen.
