Background and Objectives Patient compliant optical skin clearing requires non-invasive topical delivery of clearing agents such as glycerol. This requires reducing the skin barrier function by disrupting stratum corneum integrity, which was achieved

In vivo wound healing response post nonablative fractional laser treatment is evaluated. Seven healthy subjects receive treatments with a Fraxel re:store laser system on the forearm with pulse energies ranging from 10 to 70 mJ. The treatment sites ar

Background and Objective: Due to the significant risk profile associated with traditional ablative resurfacing, a safer and less invasive treatment approach known as fractional deep dermal ablation (FDDA™) was recently developed. We report the resu

We present a gentle mechanical method for the noninvasive transepidermal delivery of topically applied optical skin clearing agents. Optical skin clearing reduces light scattering in highly turbid skin with the aid of hyperosmotic chemicals such as g

Previous studies identified various mechanisms of light scattering reduction in tissue induced by chemical agents. Our results suggest that dehydration is an important mechanism of optical clearing in collagenous and cellular tissue. Photographic and

This paper investigates three different techniques to investigate the dynamic change of the attenuation coefficient in in-vitro hamster skin during optical skin clearing using a hyper-osmotic solution of 50% glycerol. The tissue is imaged using an am

Our recent research has shown that skin becomes temporarily transparent when a hyper-osmotic agent such as glycerol is introduced into the tissue. Local dehydration and index matching reduce light scattering which increases the penetration depth of c

The purpose of this study is to investigate the feasibility of using microneedles in comparison to Er:YAG skin surface laser ablation as a means to modify the epidermis of in-vitro hamster skin to facilitate delivery of topically applied hyper-osmoti

Previous studies suggest that optimal port wine stain (PWS) laser treatment parameters require knowledge of skin characteristics such as blood vessel size, depth, and distribution. Effective and rapid imaging modalities are not widely available. In t

The aim of this study is to investigate the feasability of using a needle-free injection gun to inject highly viscous glycerol into porcine skin for the purpose of optical skin clearing. In this study a needle-free injection device DERMO-JET by Robbi
