Skin resurfacing, or ablative lasers (such as carbon dioxide (CO2) and Er:YAG lasers, and Fraxel) direct an intense burst of laser energy onto the surface of the skin. This energy heats water within the surface layers of the skin, causing both the water and the tissue of the skin to turn to vapor. Every time the laser passes over the skin, some of the outermost layers of the skin are removed in a precise and controlled way to the appropriate depth. Unlike with traditional ablative laser resurfacing, which removes the whole of the top layer of skin in the targeted treatment area, this fractional method damages only certain zones within the selected target area, (producing tiny white dot, or pixel-like treated areas on the skin), leaving the other zones within it perfectly intact. Therefore only treating approximately 20% of the skin within the treatment area. This allows the skin to heal much faster than if the whole area was treated, as the ‘healthy’ untreated tissue surrounding the treated zones helps to fill in the damaged area with new cells. This causes collagen remodeling, skin tightening and an improvement in skin texture as the area heals.
