Photothermal ablative and non-ablative fractional resurfacing and remodeling have become extremely popular due to the lower rate of complications and side effects compared to conventional full-face resurfacing. Clinical results are nevertheless quite different and have prompted researchers to find new strategies useful to improving treatment outcomes. Sequential laser-layering techniques have been successfully used in PWS and more recently in anti-aging with good clinical results. Since temperature seems to play a key role in stimulating neo-collagen and extracellular matrix production, we thought to sequentially combined two different laser wavelenghts (1064 nm Nd:YAG and 2940 Er:YAG) in a three-step layering technique. Microscopic assessment of potential benefits induced by each laser pass at the cellular level was the aim of our study.
