Summary

Skin aging is an irreversible, slow and progressive process, being influenced mainly by age, but also by external factors such as ultraviolet radiation, smoking, alcohol, among others. Studies have shown benefits of photobiomodulation for facial rejuvenation, especially with the use of red LED. However, there is still a high level of variability in treatment parameters and frequency of application of FBM. The purpose of this study is to compare the effects of photobiomodulation with LED mask (660nm, 6.4 mW/cm², 2.67 J/cm², 5.02 mW, 21 min) on facial rejuvenation using 2 application frequencies: a group will receive 2 weekly applications for 4 weeks and another group will receive 3 weekly applications for the same period. A group with simulated photobiomodulation applied twice a week for 4 weeks will be used as a control. The treatment will be performed in female participants aged between 45 and 60 years. After a period of one month, the depth and width of wrinkles (assessment of face impressions by optical coherence tomography), evaluations of photographic images by specialists (Wrinkle Assessment Scale), as well as the quantitative analysis of the wrinkle size by the Image J software and the level of satisfaction of the participants (FACE-Q) will be compared with data collected before the start of the study. All data will be statistically analyzed according to their distribution, seeking a level of statistical significance of 5%.

Interventions

RADIATION

Photobiomodulation twice a week

The photobiomodulation will be applied with a LED facial mask, Cosmedical brand (São Paulo, Brazil), containing 92 red LEDs, 660 nm of wavelength, in continuous mode for 21 minutes, twice a week, for 4 weeks.

RADIATION

Photobiomodulation three times a week

The photobiomodulation will be applied with a LED facial mask, Cosmedical brand (São Paulo, Brazil), containing 92 red LEDs, 660 nm of wavelength, in continuous mode for 21 minutes, three times a week, for 4 weeks.

OTHER

Simulated Photobiomodulation

Photobiomodulation will be simulated, with the device turned off, twice a week, for 4 weeks. The characteristic sound of the device will be triggered by recording.
