Vitamin C, a powerful antioxidant, has the ability to neutralize or counteract damage to cells caused by free radicals( from UV Damage), which are believed to be a main cause of aging.
Increasingly, research has shown that adding topical vitamin C to skin can stimulate the production of collagen, a protein which helps form the skin’s supporting structure. Normally as we age, collagen degenerates, and as a result, our skin wrinkles. Collagen is like the springs in a bed, with time and exposure to UV radiation it becomes damaged and as a result, sags. Increasingly it has been shown that topical Vitamin C actually prevents UV radiation from damaging the underlying skin structure. Research has demonstrated a reservoir effect of about 3 days where the Vitamin C concentrations are still active.
Topical vitamin C doesn’t sensitize the skin to sunlight. Actually, there is some evidence that topical vitamin C has a protective effect against sun damage. Vitamin C works synergistically with the retinoic acid products such as Renova, Retin-A or Retinol. Results vary with each individual. Some may see changes as soon as two to four weeks while others may take as long as six to eight weeks. A maximum effect will occur at about six months.
