Evaluation of plasma skin regeneration technology for cutaneous remodeling.

Plasma skin regeneration is a novel type of skin rejuvenation technology developed over the last 3 years. Plasma is the fourth state of matter in which electrons are stripped from atoms to form an ionized gas. Although high-temperature plasmas have been used in surgery for over a decade, plasma had previously been used as a conduction medium for electric current. Unlike lasers, which rely on the principle of selective photothermolysis to deliver heat to specific targets in the skin, plasma technology delivers heat energy directly to tissue upon contact without reliance on skin chromophores. The plasma itself produces controlled thermal damage to the skin surface to elicit changes such as new collagen formation and improvement in photodamaged skin. The technology can be used at varying energies for different depths of effect, from superficial epidermal effects to deeper dermal heating.
