KSECRET's SEOUL 1988 Glow Serum: Niacinamide 15% + Yuja is a high-performance brightening treatment designed to visibly reduce dark spots and promote a clearer, more radiant complexion. Inspired by modern Seoul skincare innovation, this serum targets dullness and uneven tone while supporting overall skin clarity.

Formulated with 15% niacinamide and Citrus Junos (yuja) fruit oil, it works to brighten tired-looking skin and help create a more even-toned appearance. Niacinamide helps improve the look of discoloration and refine skin texture, while yuja adds a refreshing boost that enhances radiance and vitality.

To keep skin balanced and resilient, the formula is infused with panthenol, glutathione, and squalane for deep hydration and moisture barrier support. The lightweight, non-greasy texture absorbs smoothly, while agar gum capsules help lock in moisture and prevent water loss, leaving skin luminous, smooth, and comfortably hydrated.
