THE EFFECTIVENESS OF FRACTIONATED CARBON DIOXIDE (CO2) LASER IN THE TREATMENT OF RED STREAKS AND STREAK STREAKS

Abstract

The research developed consisted of analyzing the effectiveness of fractional CO2 laser in the treatment of stretch marks. Among the main aesthetic changes in the body, this one is like stars. The stretch mark is an atrophic aesthetic lesion, caused by a
huge stretch and a consequent rupture of the collagen and elastin fibers, responsible for the
elasticity of the skin. They affect a large portion of the population, being more frequent in
adolescent and pregnant women, although it can also present in obese people, patients with
hormonal imbalances, users of medications and patients with a genetic history. The treatments
for stretch marks vary according to the stage of evolution of the stretch and the phototype of
the patient's skin. Among the most sought after is the fractional CO2 laser, its practice
consists of promoting tissue damage through thermal damage and vaporization of cells,
leading to the stimulation of neocolagenesis, with the main target being the water present in
the tissues. The purpose of the study was to evaluate the effectiveness of using fractional CO2
laser in the treatment of red and white streaks, identifying its benefits, describing its
mechanism of action and analyzing the results obtained by the scientific literature. To this
end, a bibliographic search was carried out in the main databases, a virtual health library
(bvs); online electronic scientific library (scielo), academic Google and lilacs. Therefore,
concluding that fractional CO2 laser is effective for the treatment of stretch marks, however,
attention is needed with the patient's phototype due to complications that may occur, such as
post-inflammatory hyperpigmentation, persistent hyperpigmentation, scarring, burns and
Koebner syndrome.
