What types of products work best?
Dr. Saira points out that not all vitamin C products were created equal. She recommends finding a vitamin C serum that has a “higher concentration of active ingredients and smaller molecules which are able to penetrate deeper into the skin.” She says that “it’s imperative to seek out stabilized preparations of vitamin C, as unstabilized forms oxidize rapidly and when applied to the skin can cause irritation and actually be harmful to your skin. L-Ascorbic acid is the purest form of vitamin C and if formulated to a high standard, provides superior antioxidant defense to its derivatives. Always buy products which are packaged in bottles which protect the product from sunlight. This prevents premature oxidization of the serum and prolongs its shelf-life.”
What are the benefits of using vitamin C
“Vitamin C is a super antioxidant which protects the skin from environmental damage and prevents premature skin aging associated with UV rays and pollution. It penetrates deep into the skin’s surface and acts to neutralize free radicals which are toxic to skin cells, as well as stimulating cell renewal and supporting new collagen synthesis. Visible benefits include brighter skin with improved texture, softening of fine lines and wrinkles, and increased firmness and elasticity.” Dr. Saira also says that the vitamin is a powerful anti-inflammatory and can be a great addition for those with acne and rosacea. Additionally, when vitamin C is used with a broad spectrum SPF, it works in synergy to increase the power of the SPF, resulting in superior protection against atmospheric agine
Dr Saira has some wise words when it comes to precautions, so listen up. “L-ascorbic acid is an exfoliating acid and without use of a high factor broad spectrum SPF, it can increase photosensitivity rendering the skin vulnerable to inflammation and sun damage. If undergoing ablative skin treatments such as chemical peels or laser, it may be appropriate to take a short break from active products such as vitamin C or retinol to allow the skin’s barrier to repair. In general vitamin C serums appear as champagne or light straw-colored liquids. If your product has a brownish discoloration then discontinue use immediately. This suggests that the vitamin C has oxidized and can be harmful if applied to the skin.”
