Skin aging is a process associated with the loss of collagen. Currently, it is known that the use of technologies, cosmetics and nutraceutical supplements make up the arsenal to reduce this process. The present study aimed to evaluate the effect of topical (5% methylsilanol mannuronate on the face) and oral (200mg of organic silicon stabilized in marine collagen) use associated with fractional radiofrequency or not on improving the dermal structure of the skin. For the study, 12 menopausal women, aged between 57 and 67 years, were recruited and divided into six groups: group 1 -oral use without radiofrequency; group 2 -topical use without radiofrequency; group 3 -oral and topical use without radiofrequency; group 4 -oral use with radiofrequency; group 5 -topical use with radiofrequency; group 6 -topical use with radiofrequency. To analyze dermal thickness, the mental region of the left and right face were evaluated using ultrasound at the beginning of treatment (T0) and at the end (T1). The interventions lasted 60 days. The results of the present study show an increase in dermal density in all treatments. The best result was observed in group 6 with an increase of 24.4% in the left region and 21.1% in the right region of the face. We conclude that the association of fractional radiofrequency associated with topical and oral silicon increases dermal density in menopausal women.
