From the ABC's Health Report, presenter Norman Swan discusses topical ascorbic acid with Emeritus Professor Sheldon Pinnell, one of the world's foremost authorities on the subjects of skin aging, damage and sun protection.
Topical Vitamin C is the only ingredient which directly stimulates the skin's fibroblasts, providing the spark that produces living collagen in concert with specific chains of amino acids.
Although there are many temporary "skin tensor" products on the market, our biology dictates that there are no other alternatives for actually firming skin.
No Vitamin C = increasingly less firm skin from the age of 25 onwards.
Additional Notes:
- You cannot stimulate the skin's fibroblasts by increasing your oral intake of Vitamin C.
- Topical Vitamin C must be stable, active and able to be absorbed, and remain so throughout the life of a product once opened.
- pH, concentration, production method and the presence of other substances (particularly zinc and bioflavonoids) determine formula efficiency.
