K SECRET SEOUL 1988 Glow Serum Niacinamide 15% + Yuja – 30ml

K SECRET SEOUL 1988 Glow Serum is a high-potency brightening treatment formulated to target hyperpigmentation, dullness, uneven skin tone, and loss of radiance. It is part of the “1988” skincare line, which is inspired by traditional Korean beauty wisdom combined with modern dermatological innovation to achieve intense radiance and glass-skin clarity. The serum is powered by a high concentration of 15% Niacinamide, which helps fade dark spots, acne marks, and uneven pigmentation while improving overall skin texture.

It is enriched with Yuja (Citrus Junos Fruit Extract), a Korean citrus ingredient known for its powerful antioxidant content and naturally high Vitamin C levels, which help brighten and revitalize tired-looking skin. Additional supporting ingredients include Hyaluronic Acid for hydration, Glycerin for moisture retention, Panthenol for soothing, Adenosine for skin smoothing, Allantoin for calming irritation, and Betaine for maintaining hydration balance.

This serum is formulated to regulate excess sebum production, refine enlarged pores, strengthen the skin barrier, and improve overall skin clarity. It is especially beneficial for oily, combination, acne-prone, and dull skin types, but can also be used by normal skin needing brightening and texture improvement. Designed for individuals struggling with pigmentation, post-acne marks, and uneven skin tone, it works to restore a healthy, glowing, and smooth complexion over time.

The lightweight formula absorbs quickly without leaving heaviness, making it suitable for both morning and night use. With consistent application, it helps achieve a brighter, clearer, and more luminous “glass skin” effect while maintaining hydration and skin balance.

However, due to its high 15% Niacinamide concentration, it may not be ideal for extremely sensitive or compromised skin without patch testing. It is recommended to introduce it gradually into the routine to avoid irritation, especially for first-time users of strong actives.

How to use:

• Apply 2–3 drops on cleansed and toned skin
• Gently pat until fully absorbed, do not rub harshly
• Use morning and/or night as part of skincare routine
• Always apply sunscreen during daytime use
• Start slowly if you have sensitive skin (patch test recommended)
