As I continue to review the Medline English literature and recent international conferences regarding Fractional photothermolysis (FP) technology, applications, and indications, it becomes more obvious that this relatively new modality is one of the most significant milestones in laser technology and skin resurfacing.

Successful conditions treated with non-ablative fractional lasers reported in the literature include acne scarring; dyschromia and fine wrinkling of photoaging on the face, chest, neck, and hands; melasma; poikiloderma of Civatte; nevus of Ota; scars; minocycline hyperpigmentation; telangiectatic matting; residual hemangioma; granuloma annulare; colloid milium; and disseminated superficial actinic porokeratosis.

Fraxel-technology

An advance in 2007 was the introduction of ablative FP (AFP), which results in significantly greater improvement in skin laxity and textural abnormalities. There is no doubt that AFP has demonstrated significantly greater improvement than non-ablative FP in reducing acne scarring and skin redundancy and laxity associated with photoaging.

Through the induction of microthermal zones of injury, FP technology stimulates a robust and rapid wound healing response resulting in improvement in a diversity of aesthetic, inflammatory, and preneoplastic skin disorders.

Further investigation into the technology and diverse array of cutaneous conditions that can benefit from FP will continue and bring additional data to use in determining treatment parameters and identifying new apppliations.
