Iontophoresis is an effective and painless method of delivering the Vitamin C by using bipolar electric fields to propel molecules across intact skin and into underlying tissue. It is used as a means of delivering the vitamin C across the skin for the management of a variety of medical conditions.

L- Ascorbic acid polypeptide complex is a water stable, soluble form of Vitamin C, which is able to penetrate the outer layers of the skin. Vitamin C, a powerful antioxidant, has the ability to neutralize or counteract damage to cells caused by free radicals which are believed to be a main cause of aging. Topical vitamin C has shown to protect the skin from UV damage caused by prolonged sun exposure by reducing the amount of free radical formation and/or sunburn cells. Exposure to UV light has also shown to decrease the naturally occurring vitamin C levels in the skin, thus topical application of vitamin C restores these photoprotectant levels. Other studies also suggest that vitamin C may play a part in the collagen biosynthetic pathway by activating collagen metabolism and dermal synthesis of elastic fibres.
