Fractional laser treatment with the 1,550nm erbium fiber laser (Fraxel® Laser, Reliant Technologies) has bridged the gap between the ablative and nonablative laser modalities used to treat the epidermal and dermal signs of skin aging. By targeting water as its chromophore, the laser induces a dense array of microscopic, columnar thermal zones of tissue injury that do not perforate or impair the function of the epidermis. The significant skin remodeling that ensues can be used to treat, with limited downtime, epidermal pigmentation, melasma, and rhytides, as well as textural abnormalities that include acne-related and surgical scars.
Although ablative laser modalities remain the gold standard for the treatment of photoaging, most patients cannot tolerate the 1-2 weeks of downtime required with these procedures.
