fractional photothermolysis

fractional photothermolysis

A method of laser skin resurfacing in which laser energy is directed at pinpoint, broadly separated islands of skin instead of larger swaths to remove cosmetically unappealing blemishes in skin color and texture. The technique is used to minimize the time it takes to restore normal epithelium to the treated surface.
Synonym: fractional ablation

Fractional Photothermolysis: To determine the efficacy of fractional photothermolysis in striae distensae, 22 women with striae distensae were treated with two sessions each of fractional photothermolysis at a pulse energy of 30 mJ, a density level of 6, and eight passes at intervals of 4 weeks and response to treatment was assessed by comparing pre- and post-treatment clinical photography and skin biopsy samples.
To assess and compare the efficacy and safety of nonablative fractional photothermolysis and ablative CO(2) fractional laser resurfacing in the treatment of striae distensae, 24 ethnic South Korean patients with varying degrees of atrophic striae alba in the abdomen were enrolled in a randomized blind split study and were treated with 1,550 nm fractional Er:Glass laser and ablative fractional CO(2) laser resurfacing.
A hybrid technique called ablative fractional photothermolysis creates tiny columns of ablation, while leaving the surrounding untreated tissue available as a reservoir for rapid healing.
Fraxel gets its name from fractional photothermolysis, which means that with every treatment, the area treated is 15 to 25 per cent of the surface area of the skin, depending on whether the patient has milder or deeper wrinkles and lines.
