Official title: Light Reflection on Human Skin in Whole-Body Photobiomodulation Therapy: Clinical Trial

Run by Universidade Federal de Sao Carlos · NCT06866522 · Data updated 2026-11-12

This study is testing how different skin types reflect light during a whole-body therapy using red and infrared light to see if it can be improved for everyone.

What this trial studies

This study investigates the effects of photobiomodulation therapy (PBMT) on human skin by measuring the reflection of light from different skin phototypes. Participants aged 18 to 30 will be divided into three groups based on their skin type and will undergo whole-body PBMT using red and infrared light. The study aims to quantify the amount of light reflected from the skin during this therapy, which has not been previously established. The findings could provide insights into optimizing PBMT for various skin types.

Why it matters

Potential benefit: If successful, this study could enhance the effectiveness of photobiomodulation therapy by tailoring it to individual skin types.

How similar studies have gone: While photobiomodulation therapy has been studied, this specific approach focusing on light reflection and skin phototype is novel and has not been extensively tested.
