A novel microgel complex delivers acne medicine deep into follicles while demonstrating high patient tolerance.

Acne vulgaris is a common skin disease that is difficult to treat due to its multifactorial etiology. The presence of sebum and keratinocytes within the hair follicle often prevent medication from penetrating deep into the follicle where the causal bacteria are to be found. Medications able to penetrate into the follicle are often irritating to the skin.

Application of a topical biomimetic electrical signaling technology to photo-aging: a randomized, double-blind, placebo-controlled trial of a galvanic zinc-copper complex.

Background: The first signs of facial skin photo-aging often occur in the skin of the periorbital area and include sagging, loss of firmness and definition, and sallowness. Epidermal wounds have been shown to alter the trans-epithelial electrical potential creating an electric signal that directs cell migration in epithelial wound healing; this electric field declines sharply with age. A topical galvanic zinc-copper complex, which couples elemental zinc and copper to create a biomimetic electric field, has demonstrated anti-inflammatory activity and extracellular matrix improvement in vitro, including collagen and elastin production.
