Ultrassom microfocado no rejuvenescimento facial: uma revisão integrativa da literatura

Abstract

Skin aging is influenced by external factors, such as sun exposure, and internal factors, such as hormonal changes and decreased cellular activity, resulting in thinner, drier and wrinkle-prone skin. Given the growing demand for non-invasive aesthetic procedures, microfocused ultrasound has gained prominence for its ability to stimulate collagen production and reduce signs of aging, presenting low risk and good results. This study aimed to analyze the effectiveness of microfocused ultrasound in facial rejuvenation, based on articles published mainly in the last five years, available in databases such as PubMed, ScienceDirect, Google Scholar and LILACS. The research highlighted that the skin is made up of the epidermis, the dermis, rich in collagen and elastin, the hypodermis and the superficial muscular aponeurotic system (SMAS). With aging, there is a decrease in collagen, elastin and hyaluronic acid, resulting in sagging and wrinkles. Microfocused ultrasound works by stimulating collagen production through thermal microlesions that reach the SMAS, being effective in improving skin quality. The pain was considered moderate, and the use of anti-inflammatories, although theoretically contraindicated, did not compromise the results. Patients with severe sagging were excluded, with surgery being more indicated in these cases. The use of different tips during the procedure increased its effectiveness, and the adverse effects observed, such as redness and swelling, were mild and temporary. The study concludes that microfocused ultrasound presents low risk and is effective in reducing signs of aging.
