COSRX - skincarebykaye review for The Niacinamide 15 Serum

A Highly concentrated serum that combines the maximum concentration of niacinamide with optimal ratios of synergistic ingredients for total acne control. It has a light as water liquid formulation that absorbs quickly to leave the skin feeling refreshed and calmed. This highly concentrated 15% Niacinamide serum cares all about acne and effectively controls excess sebum and tightens pores. This serum brightens my skin tone and improves my skin texture.
