Melasma, a hypermelanosis of the face, is a common skin problem of middle-aged women of all racial groups, especially with dark complexion. Its precise etio-pathogenesis is evasive, genetic influences, exposure to sunlight, pregnancy, oral contraceptives, estrogen-progesterone therapies, thyroid dysfunction, cosmetics, and drugs have been proposed. Centro-facial, malar, and mandibular are well-recognized. ⋯ Quasi-drugs, placental extracts, ellagic acid, chamomilla extract, butylresorcinol, tranexamic acid, methoxy potassium salicylate, adenosine monophosphate disodium salt, dipropyl-biphenyl-2,2'-diol, (4-hydroxyphenyl)-2-butanol, and tranexamic acid cetyl ester hydrochloride, in addition to kojic and ascorbic acid have been used. Chemical peeling is a good adjunct. Laser treatment is worthwhile.

Clinical TrialA bipolar radiofrequency, infrared, vacuum and mechanical massage device for treatment of cellulite: a pilot study.
Cellulite has a complex and multifactorial etiology. Synergistic action on treating cellulite has gained support in the treatment of cellulite. This study evaluated safety and efficacy of a bipolar radiofrequency, infrared, vacuum and mechanical massage device for cellulite treatment and reduction of body measures. ⋯ There was a significant reduction of the hip circumference (p = 0.001), however, no changes in thigh circumferences were observed (p = 0.4). CSS has improved specifically on both buttocks [p = 0.002 (left side) and p = 0.038 (right side)], and no changes were observed on thighs. The studied device demonstrated efficacy in the reduction of cellulite severity and body circumference measures in the buttocks.

Effect of incoherent LED radiation on third-degree burning wounds in rats.
The main physiological characteristics in a burn process are the increase of the capillary permeability and the occurrence of edema and exudation. Light-emitting diode (LED) has been proposed as treatment of burning. This study investigated the effects of LED on the repair process of rat skin submitted to a third-degree burning. ⋯ The inflammatory cells as well as the damaged area at the 8th day after burns were significantly lower for the LED-treated group when compared to control. Furthermore, the LED phototherapy effect on cellular migration was even more pronounced at the 16th day. Our results indicated that the treatment with a LED system was clearly effective in reducing the number of inflammatory cells and improving the healing process in an experimental model of third-degree burnings.
