ZO Skin Health Ossential C-Bright 10% Vitamin C Serum 1.7 oz

This vitamin C product has received mostly positive reviews from customers, with many experiencing an improvement in their skin's brightness and texture. The main reason customers love this product is due to its ability to act as both a pore-minimising primer and an effective skincare treatment. The texture is silky and spreadable, and it includes potent vitamin C and niacinamide. However, some customers have complained that their tubes only had half of the product, and there doesn't seem to be an option for a refund. One other con mentioned was that it might lighten the complexion slightly if used with tinted sunscreen. Overall, it seems like a high-quality product that is worth the investment.
