Current Status of Fractional Laser Resurfacing

Fractional laser resurfacing, developed from laser hair transplantation technology, has been used since 2007 to treat skin conditions such as photoaging, acne scarring, and dyschromia. The technique involves fractionation, which allows for deeper tissue penetration and results in tissue contraction, increased collagen production, and tissue remodeling. Adjustments in treatment parameters enable customization for different skin types, particularly higher Fitzpatrick skin types (IV to VI), and facial subunits. The effects of these treatments have been shown to last for several months due to tissue remodeling. Additionally, fractional lasers are associated with a short recovery time and a high safety profile, although surgeons should be mindful of the limitations and potential risks. Adjuvant treatments, including face-lifts, product deposition, and platelet-rich plasma, are also being explored to enhance results.
