Os dispositivos de luz intensa pulsada promovem o princípio básico de absorção de fótons por cromóforos endógenos ou exógenos encontrados na pele. A luz pulsada é convertida em energia calorífica, a qual coagula o alvo desejado (foto-termólise seletiva). Essa tecnologia envolve um sistema de lâmpadas paralelas de xenônio e capacitores contidos, que é aplicada diretamente í superfície da pele. Seu espectro de emissão varia de 500 a 1300 nm, apresentando assim, uma grande versatilidade de tratamentos. Para a construção deste artigo de revisão, a metodologia adotada foi uma pesquisa bibliográfica em revistas científicas da área de saúde indexadas no Pubmed (entre os anos de 1989 a 2010) que abordam os efeitos terapêuticos e fisiológicos da terapia de luz intensa pulsada. Dentre os efeitos terapêuticos aplicados í terapia com luz intensa pulsada, destacamos a remoção de pelos, tratamento de lesões pigmentadas, lesões vasculares, acnes, e rejuvenescimento da pele. Uma das maiores vantagens dos dispositivos de luz intensa pulsada é em relação í sua versatilidade e a economia. Esses dispositivos são mais vantajosos devido a sua capacidade em tratar grandes áreas de pele. No entanto, mais ensaios controlados comparativos com um período de acompanhamento estendido são necessários para determinar diferenças significativas da LIP e outras terapias.
Palavras-chave: luz intensa pulsada, efeitos fisiológicos, efeitos terapêuticos.
