Our Vitamin C serum combines four potent antioxidants to help reduce fine lines, boost collagen production, fade dark spots, and protect against UV damage—leaving your skin firmer, smoother, and visibly radiant skin. If customers have sensitive skin and have not been able to use other vitamin C serums this may be the one for them. As a fat-soluble derivative of vitamin C, ascorbyl palmitate will be non-irritating for sensitive skin types, but more stable when exposed to air and light than ascorbic acid, which is typically used in most Vitamin C serums. Ascorbyl palmitate has milder effects on the skin than ascorbic acid with just as profound brightening effects. Four antioxidants in ONE: Combines Vitamin C with other plant-based antioxidants like Tremella Mushroom for optimal effectiveness. Advanced anti-aging, Reduces fine lines and wrinkles while boosting collagen production for firmer, more youthful skin. Packaged in 1 oz/30 ML, Miron Glass Bottle with tamper proof dropper lid
