Pulsed Light and Heat Energy in the Treatment of Pigmented Lesions

Removal of pigmented lesions by non-ablative Laser or Intense Pulsed Light (IPL) systems are gaining increasing popularity. To avoid thermal damage to the epidermis these systems require a skin cooling device. Radiancy's pulsed light and heat energy technology (LHE™) was found safe and effective for hair removal without the need for skin cooling. Therefore, LHE based systems are simple to operate, compact and cost-effective. In this study the efficacy and safety of the LHE based system, SkinStation™, for the removal of pigmented lesions was addressed. Thirty one areas with pigmented lesions, mostly lentigines, were treated with SkinStation. Photographs and measurements of the lesions were taken before the first treatment and after completion of treatments. An average of 3.72 treatments were applied every 2 to 4 weeks. After completing the treatment regimen lightening of lesions was observed in all treated areas except two. Reduction of lesion dimensions was seen in most treated areas and complete disappearance of lesions in five. Side effects were mild and resolved without specific care. No scars were observed. The results of this study show that the treatment of pigmented lesions by LHE is highly safe and effective.
