Vitamin C is practically the most important antioxidant when it comes to skin health. It prevents and reverses pigmentation, aids in collagen formation and provides protection against UVA and UVB rays. It is particularly important to use a Vitamin C product in the summer months when the sun exposure is at the highest.

Vitamin C is a powerhouse antioxidant, however it can also turn into a free radical. Therefore, when choosing the right vitamin C product, look for a combination that includes other antioxidants like Vitamin E, Vitamin A, and Coenzyme Q-10 formulations, that ensure a stable delivery of Vitamin C.

Vitamin C is also vulnerable to deterioration in the presence of air or light, so the packaging of Vitamin C product is extremely important. Look for opaque, airless containers. When Vitamin C oxidizes, it changes to a yellow or brownish tint. Be weary of products that mask the freshness of Vitamin C by adding colorings such as Yellow 6 or fragrances.

Penetration of Vitamin C can be significantly enhanced by 100 fold when combined with micro needling, a painless process of creating micro channels in the skin. A micro roller or a Derma Roller is a hand held device comprised of micro needles made of surgical steel that can be gently rolled on the skin before applying the product.

Vitamin C will soak up all of those damaging UVA and UVB rays and shield your skin from sun damage. So, wear your Vitamin C with your SPF boosting your sun protection before you head out each morning!
