Fotobiomodulação como ferramenta auxiliar na hidratação cutânea

Abstract

Cutaneous dehydration is one of the changes caused by aging that has a high frequency. Although not considered a dysfunction in itself, xerosis can cause discomfort due to the visual and sensory appearance of the skin. The use of photonic techniques such as photobiomodulation (PBM) using LASER or LED has shown numerous benefits for skin healingr. The present study verified the ability of FBM to improve skin hydration associated with a cosmetic treatment protocol for cutaneous xerosis. The experimental model consisted of 3 sessions of cutaneous hydration performed in 60 volunteers, randomly divided into 2 groups, being the Experimental group where the hydration protocol will be associated with the application of red LED (660 nm, 3 J punctual application on the entire face) in each session of treatment and the control group that received the same hydration protocol and placebo LED irradiation. The results were evaluated by cutaneous bioimpedance on the first day and one week after the last day of treatment, and the appearance of the skin was evaluated by evaluators blinded to the treatment protocol used. The data obtained were statistically compared. We observed with this study that there is a role for the use of PBM in the process of reversal of cutaneous xerosis, we identified an improvement in the amount of water in the skin without changing the amount of oil. PBM can be used in the treatment of patients who show signs of skin dehydration, senile xerosis, who are looking for a safe, non-invasive technique with no side effects, as well as patients who have contraindications to the use of other therapies available in the aesthetic market. Emphasizing that it is a very useful tool for hydration of oily biotype skins, since it increased the water gradient and there was no change in the percentage of oil.
