Analysis of Depth of Ablation,Thermal Damage, Wound Healing, and Wound Contraction With Erbium YAG Laser in a Yorkshire Pig Model.

Background And Objectives: The erbium YAG laser is commonly used for skin resurfacing. It is known that varying the pulse duration can influence residual thermal damage and wound healing. Our study used a porcine model to evaluate a broad range of settings in a comparison of depth of ablation, depth of residual thermal damage (RTD), and wound contraction employing both a full coverage and fractional hand piece with an erbium YAG laser.

The Use of a Fractional Ablative Micro-Plasma Radiofrequency Device in Treatment of Striae.

Objective: To evaluate the efficacy of a fractional ablative micro-plasma radiofrequency (RF) device in the reduction of the appearance of abdominal striae.

Methods: Five female patients (age range, 30-60) with abdomen striae alba (n=4) and striae rubra (n=1) were enrolled in the study. Skin type distribution among the 5 patients was two type II, one type III, and two type IVs.

A split face study to document the safety and efficacy of clearance of melasma with a 5 ns q switched Nd YAG laser versus a 50 ns q switched Nd YAG laser.

Background And Objectives: To determine the safety and efficacy of a 50 ns Q switched Nd YAG laser vs. a 5 ns Q switched Nd YAG laser for clearance of melasma. To compare subject satisfaction, efficacy, and comfort level between the two lasers.

Periocular hyperpigmentation: a review of etiology and current treatment options.

Background: Periocular "dark circles" fall among the most difficult chief complaints to address. In most cases, we have little information regarding etiology and no gold-standard treatment option. The extent of the problem is reflected in the sheer number of products on the market advertised to either lighten or cover the pigmentation.
