This powerhouse serum is formulated with 15% niacinamide, the maximum concentration for visibly refining pores, reducing excess oil, and improving uneven skin tone. Enhanced with Acetyl Glucosamine (NAG) to gently exfoliate and fade post-acne marks, and Zinc PCA to balance oil-water levels, it delivers total acne control while supporting a clearer, smoother complexion.

The lightweight texture absorbs quickly without stickiness, making it perfect for daily use under skincare or makeup. With Allantoin to soothe and strengthen the skin barrier, it’s ideal for tackling breakouts while maintaining hydration.
