- Refreshed skin: Helps refine and refresh the look of skin.

Texture & Application
The serum has a lightweight, fluid texture that spreads easily and absorbs without a heavy or sticky after-feel. It layers cleanly under other products, so it fits neatly into the treatment step of a routine. In a routine it sits after cleansing and toning, before moisturizer.
What Makes It Special
The formula centers on Niacinamide, giving the product a clear focus rather than a long, unfocused ingredient list. That makes it easy to understand where it fits and what it is for. It is positioned for consistent, everyday use rather than as an occasional one-off treatment. As part of a Korean skincare lineup, it reflects a broader emphasis on gentle, routine-friendly care.
