All skin types can benefit from vitamin C. It’s a matter of finding the best type of vitamin C product for your specific skin type and skin needs. The usage of this ingredient is as individual as we are. There are those who fall on the sensitive side of the scale and vitamin C may cause irritation and may not be the best ingredient for them. Niacinamide is a gentle alternative that has similar benefits to vitamin C and protects from sun damage and free radicals.
