ORDINARY NIACINAMIDE 10% + ZINC 1% 30ML

The Ordinary Niacinamide 10% + Zinc 1% is a high-strength vitamin and mineral serum formulated to reduce skin blemishes and congestion. This water-based formula combines 10% pure niacinamide (vitamin B3) with 1% zinc PCA to improve skin barrier function, smoothness and radiance. This serum is best applied morning and evening before heavier creams. It should not be used simultaneously with vitamin C products - if using both, apply them at different times of day. While this formula helps with blemishes and skin tone, it is not an acne treatment. The product requires patch testing before first use and should only be applied to unbroken skin. If irritation occurs, discontinue use and consult a physician.
