BACKGROUND Blond and white hair removal by laser is a complicated task with weak satisfactory results due to the deficiency in laser-absorbing chromophore. OBJECTIVE To investigate if repetitive sessions of photodynamic therapy (PDT) using external application of liposomal Rose bengal (RB) photosensitizer followed by intense pulsed light (IPL) exposure enables removal of gray and white hair. ...

BACKGROUND Intense pulsed light (IPL) generates high-intensity short flashes of visible light and has been used for about 10 years to improve dermatological conditions such as telangiectasia, pigmented lesions, and skin aging. Although these systems deliver a moderate dose (10-30 J/cm(2)) of visible light, this dose is delivered during a short pulse (2-5 milliseconds), which implies a very high...

Intense pulsed light (IPL) is effective for the treatment of lentigines, telangiectasia, and generalized erythema, but is less effective in the removal of skin wrinkles. Fractional laser is effective on skin wrinkles and textural irregularities, but can induce postinflammatory hyperpigmentation (PIH), especially in Asians. This study evaluated the safety and efficacy of ablative fractional lase...

BACKGROUND AND OBJECTIVES Intense pulsed light (IPL) systems are high-intensity light sources, which emit polychromatic light. Unlike laser systems, these flashlamps work with noncoherent light in a broad wavelength spectrum of 515-1,200 nm. These properties allow for great variability in selecting individual treatment parameters and adapting to different types of skin types and indications. Th...

BACKGROUND Photothermal destruction of hair shaft melanin with intense pulsed light (IPL) and neodymium:yttrium-aluminum-garnet (Nd:YAG) laser has become an effective treatment of hair removal. AIMS Our aim was to compare efficacy, satisfactory levels, safety, and side effects of Nd:YAG and IPL in hair reduction. METHODS This was a prospective randomized intrapatient, right-left, assessor-b...

OBJECTIVE The aim of this work was to verify the usefulness and efficacy of treating superficial vascular lesions of the face using rhodamine intense pulsed light (r-IPL). SUBJECTS AND METHODS Fifty patients suffering from telangiectasias of the face were enrolled and subsequently treated 4 times (every 20 days) with a new intensified r-IPL system optimized at the same wavelength as the dye l...

Background There is a considerable need for effective and safe treatment for acne vulgaris. Objective In a systematic review with an evidence-based approach to assess the effects of optical treatments for acne vulgaris. Methods Original publications of controlled clinical trials were identified through searches in PubMed and the Cochrane Library. Results A total of 16 randomized controlled tria...

BACKGROUND Among the different approaches for improving the effectiveness in the treatment of Capillary Malformations type Port Wine Stain (CM type PWS) are the intense pulsed light sources. There are few clinical studies prove useful in the treatment of CM. Furthermore, no studies have been published yet demonstrating the histological effects of IPL in CM. OBJECTIVES To assess the histologic...

This study was conducted to evaluate the inactivation of Bacillus cereus spore in mesquite flour with intense pulsed light (IPL) and gamma radiation. The physical, chemical, toxicity treated were also investigated. results showed that up 3.51 log10CFU/g B. achieved 8 kGy radiation, 1.69 reductions could be after 28s catalytic IPL exposure. Although chemometric analysis 9-hydroxy-10,12-octadecad...

BACKGROUND Discoid lupus erythematosus (DLE) is restricted to the skin, mostly the face, often chronic and disfiguring. Standard medical therapies include topical corticosteroids and antimalarials. This is a retrospective long-term follow-up of refractory DLE treated with different lasers and intense pulsed light (IPL). METHODS AND MATERIALS Sixteen patients with histologically confirmed DLE ...
