Microagulhamento, uma terapia que induz a produção de colágeno

RESUMO

Os procedimentos estéticos têm sido cada vez mais procurados, com objetivos que vão desde a satisfação pessoal até o tratamento de patologias. Todos os dias surgem no mercado novos equipamentos, novas técnicas e novos fármacos objetivando harmonia, juventude e uma aparência natural. Um dos tratamentos que tem se mostrado muito eficiente é o estímulo percutâneo de colágeno, uma técnica regenerativa recente, relativamente simples e com ampla base científica. O método do tratamento consiste em lesionar as camadas mais superficiais da pele, a fim de provocar uma inflamação controlada e estimular a síntese de componentes estruturais de tecido conjuntivo dérmico, como fibras do colágeno tipo I, fibronectina e glicosaminoglicanos, e também uma variedade de fatores de crescimento. A característica especial do microagulhamento é que, ao contrário de outras abordagens para regeneração cutânea, trata-se de um método minimamente invasivo. Portanto, está associado a uma fase particularmente curta de cicatrização e também exclui riscos de alterações sérias ou permanentes à pele.

Palavras-chave – Microagulhamento; Colágeno; Dermaroller; Pele humana; Inflamação.

ABSTRACT

The demand for aesthetic procedures has been increasingly high, from personal satisfaction to medical treatment. New equipment, techniques, and pharmacological agents are seen in the market every day, aiming harmony, rejuvenation, and a look-like appearance. Amongst them, one of the most efficient is the percutaneous collagen stimulus, a recent and simple technique with solid scientific evidence. This treatment consists on damage to the more superficial skin layers to trigger a controlled inflammation and to stimulate the synthesis of structural components such as dermal connective tissue, collagen type I, fibronectin, and glycosaminoglycans, along with a variety of growth factors. The special feature of microneedling is that, contrary to the other therapies for cutaneous regeneration, it is a minimally invasive method. Thus, it can be associated to an extremely short healing period while still excludes severe or permanent changes to the skin.

Key words – Microneedling; Collagen; Dermaroller; Human skin; Inflammation.
