Fractional CO₂ Laser

The active laser medium is a mixture of 3 gases consisting of 10–20% carbon dioxide, 10–20% nitrogen, and the remainder is helium. The carbon dioxide laser produces a specific wavelength of light in the infrared spectrum (10,600 nm).

Carbon dioxide laser beams penetrate the top skin layers reaching into the dermis. It creates tiny microscopic areas of thermal damage that stimulate new collagen production and replace damaged skin surface by new epidermal cells.

Traditional ablative carbon dioxide laser resurfacing has been largely replaced by fractional carbon dioxide lasers, which provide excellent results with fewer complications.
