Cos-IQ 5% Niacinamide Face Serum is a lightweight and effective formula designed to promote a clear, balanced, and healthy-looking complexion. Enriched with high-grade 5% Niacinamide (Vitamin B3), this serum helps visibly improve uneven skin tone and reduce the appearance of blemishes with consistent use.

Clinically proven to support clearer skin within weeks, Cos-IQ 5% Niacinamide Face Serum works by helping to regulate melanin production, which can reduce the look of dark spots, face marks, and uneven pigmentation. The result is a smoother, brighter, and more even-toned complexion that looks naturally radiant.

Beyond brightening benefits, Cos-IQ 5% Niacinamide Face Serum also acts as a powerful antioxidant, helping to reduce oxidative stress caused by environmental factors. Its gentle yet effective formulation makes it suitable for daily use on most skin types, leaving your skin feeling fresh, balanced, and visibly healthier every day.
