L-asorbic acid
The only form of Vitamin C that the body can recognize and utilize to promote collagen production to battle the damaging effects caused by the sun. This vital vitamin acts as a key anti-oxidant to combat sun-induced free radicals and is also essential for collagen production to maintain elastic, firm, smooth skin.
Hydrolized ascorbic acid
An exciting development in cosmetic chemistry because its chemical structure enables it to bypass the normal conversion required by the skin to facilitate entry into the skin cell, where it is utilized to promote collagen synthesis.
Tyrosine
Medical literature states that when tyrosine is combined with ascorbic acid, it helps to promote regeneration of new connective tissue through the stimulation of fibroblasts and thereby enabling them to make more collagen.
Resveratrol
An exceptional free radical scavenger extracted primarily from mulberries and grapes. Resveratrol is believed to protect collagen through two mechanisms:
1) by inhibiting enzymes that degrade collagen, and
2) by supporting existing collagen structures.
