The Perfect C Serum 17% by MyChelle Dermaceuticals is a high-potency vitamin C serum that offers various benefits for the skin. It helps brighten the complexion, reduce the appearance of dark spots, and provide antioxidant protection against environmental damage. The serum is fragrance-free, vegan, and cruelty-free. However, it does not provide sun protection, so it's recommended to use sunscreen in conjunction with this product.
