Vitamin C is an antioxidant that slows the rate of free-radical damage. Free radicals are unstable molecules that damage collagen and cause skin dryness, fine lines and wrinkles. New research shows that ascorbic acid 2-phosphate, a derivative of vitamin C, not only neutralizes free radicals, but also reverses DNA damaged.
Vitamin C is widely used in skincare, it can get confusing as there are many forms, each with its own name formulated in varying amounts. Here's what you need to know:
- The forms of vitamin C that are proven most stable and effective are: ascorbic acid, L-ascorbic acid, ascorbyl palmitate, sodium ascorbyl phosphate, retinyl ascorbate, tetrahexyldecyl ascorbate, and magnesium ascorbyl phosphate.
- A proven range for vitamin C effectiveness is between 0.3% and 10%, depending on the variety.
- All antioxidants, including vitamin C, are vulnerable to deterioration in the presence of air and light. If a product containing antioxidants does not come in opaque packaging that reduces air exposure, don't buy it!
Benefits of Vitamin C:
- Protect skin cells and skin's support structure from UV-related damage
- Improve the appearance of sun-damaged skin
- Strengthen skin's barrier response
