BACKGROUND AND OBJECTIVES This study had two objectives: subjective evaluation of overall skin rejuvenation effects of relatively short-wavelength intense pulsed light (IPL) and objective changes in basic skin tone as measured by a spectrophotometer. STUDY DESIGN/MATERIALS AND METHODS Twenty-five women selected at random received a series of three IPL treatments. Efficacy was evaluated over a...

The recent rapid growth in demand for non-invasive light-based cosmetic treatments such as removal of unwanted facial and body hair, skin rejuvenation, removal of age-related and sun induced blemishes including pigment and vascular lesions as well as lines and wrinkles has led to a boom in the sale of medical devices that claim to treat these conditions. The often onerous safety regulations gov...

BACKGROUND The Q-switched Nd:YAG laser was among the first non-ablative lasers to be used. High-fluence photoacoustic Q-switched laser treatments were shown to produce results akin to those seen with some ablative lasers. Previous low-fluence, non-thermal, Q-switched Nd:YAG lasers produced almost no results. OBJECTIVE The purpose of this study was to evaluate a new combined photoacoustic/phot...

The Intense Pulsed Light (IPL) may be used for the treatment of acne, photoepilation, photorejuvenation and more recently their use has been advocated for treatment of meibomian gland dysfunction and dry eye. For the treatment of dysfunction of the meibomian gland, Intense Pulsed Light was used with the same acne treatment settings in the scenario Fitzpatrick type 1, fluent between 8 and 12 J/c...

BACKGROUND AND OBJECTIVE The effects of fractional resurfacing on eyelid tightening and aperture are unknown. Our purpose was to retrospectively examine the potential for eyelid tightening and eye-aperture opening in patients treated with nonablative fractional resurfacing for facial photorejuvenation. STUDY DESIGN/MATERIALS AND METHODS Fractional laser treatments using a 1,550-nm erbium-dope...

BACKGROUND AND OBJECTIVES Cryogen spray cooling (CSC) is used to pre-cool the epidermis during dermatological laser procedures such as treatment of port wine stain (PWS) birthmarks, hair removal, and non-ablative photorejuvenation. Thus far, heat transfer studies related to CSC optimization have assumed a flat surface but clinical observation suggests that human skin indents due to the force of...

The aim of this study was to determine the effects of intense pulsed light (IPL) on cell proliferation and the secretion of vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMPs) in human fibroblasts and vascular endothelial cell lines, and to investigate the effects of IPL on the mRNA expression levels of type I and III procollagens in cultured human fibroblasts. Foresk...
