Abstract
The present invention is based on the development of a method for cosmetic delivery of L-ascorbic acid-containing compositions to the layer of the skin wherein collagen formation takes place to enhance production of collagen and thereby combat some of the effects of aging and oxy-radical damage on skin. Sufficient electric pulses applied to a region of skin surface temporarily create new pathways through the lipid skin barrier, thereby delivering an L-ascorbic acid-containing composition through the lipid skin barrier and enhancing production of collagen in the region of the skin so treated. A handheld electrical pulser apparatus, optionally table-top adaptable, and methods of use for cosmetic treatment of degenerative skin conditions are provided by the invention.
