Resumo
O melasma é uma disfunção da pele que leva a formação de manchas
acastanhadas, principalmente no rosto. Mais comum em mulheres, especialmente durante a gravidez, uso de anticoncepcionais e exposição solar intensa. Embora seja uma condição benigna, pode afetar à autoestima. Os tratamentos para o melasma incluem peelings, microagulhamento, fotoproteção, produtos clareadores, lasers e luz intensa pulsada (LIP). A LIP é um dispositivo que emite pulsos de luz de alta intensidade, visando à absorção de fótons pelos cromóforos da pele, levando à destruição da estrutura alvo do melasma. Objetivo: revisar na literatura sobre à eficácia da LIP no tratamento do melasma. Métodos: foram pesquisadas as bases de dados eletrônicas Pubmed, Cochrane e BVS, utilizando-se descritores indexados no Mesh e DeCS para seleção dos artigos elegíveis dos últimos 11 anos. Resultados: foram selecionados 04 artigos de acordo com os critérios de elegibilidade pré-definidos. Destes, 01 demonstrou resultado positivo com a LIP aplicada
isoladamente, 02 com a LIP associada a laser e 01combinada com agentes clareadores tópicos. Conclusão: O tratamento com LIP demonstrou eficácia na redução da pigmentação e tamanho das lesões de melasma, sendo considerado um recurso terapêutico seguro. A combinação da LIP com substâncias clareadoras e bloqueadores solares busca resultados de longa duração e menor recidiva, e a combinação com outras terapias fotoseletivas podem resultar em resposta mais imediata, mas com maior chance de reincidência das manchas.
Introduction: Melasma is a skin disorder that leads to the formation of brownish spots, mainly on the face. More common in women, especially during pregnancy, use of contraceptives and intense sun exposure. Although it is a benign condition, it can affect self- esteem. Treatments for melasma include peelings, microneedling, photoprotection, bleaching products, lasers and intense pulsed light (IPL). IPL is a device that emits high- intensity pulses of light, aimed at absorbing photons by the skin's chromophores, leading to the destruction of the melasma target structure. Objective: to review the literature on the effectiveness of IPL in the treatment of melasma. Methods: Pubmed, Cochrane and VHL electronic databases were searched, using indexed descriptors in Mesh and DeCS to select eligible articles from the last 11 years. Results: 04 articles were selected according to the predefined eligibility criteria. Of these, 01 showed a positive result with IPL applied alone, 02 with IPL associated with laser and 01 combined with topical bleaching agents. Conclusion: Treatment with IPL was effective in reducing the pigmentation and size of melasma lesions, being considered a safe therapeutic resource. The combination of IPL with whitening substances and sunblocks seeks long-lasting results and less recurrence, and the combination with other photoselective therapies may result in a more immediate response, but with a greater chance of recurrence of the spots.
