Intradermal Delivery of Calcium Hydroxylapatite With Fractionated Ablation

The absorption of biostimulatory particulate matter following its application to fractional skin defects remains poorly understood, and even less is known about its in vivo impact in terms of tissue integration. The objectives of this study are twofold: (1) to evaluate the potential of calcium hydroxylapatite (CaHA) to penetrate through skin treated with a fractional laser; and (2) to assess the effectiveness of clinical laser scanning microscopy technologies in monitoring the effects of such treatment over time.
