Fractional delivery of laser energy remains one of the most widely discussed topics in the field of cosmetic dermatology, as evidenced at the American Academy of Dermatology (AAD) meeting in February where multiple discussions revolved around this subject, using several different wavelengths. These devices will greatly expand cosmetic dermatologists' ability to offer both ablative and nonablative laser treatment.
Aging leads to an increase in facial skin volume, which is related, in part, to increased skin laxity and loss of elasticity. Such redundancy responds to natural gravitational forces by a cosmetically unappealing sagging appearance. Ablative laser wavelengths can correct the sagging by inducing volumetric reduction in facial skin.
As my colleagues and I reported last year, ablative fractional resurfacing (AFR) achieves specific and significant volumetric reduction in facial skin. (1,2) Volume reduction can play a major role in dermatologists' strategies to maintain skin appearance. Removal of...
