RLT is proven to reduce overall body circumference measurements of the waist, hips, thighs, buttocks, and upper arms causing a “body contouring” effect. A study published in the National Institute of Health found that red light therapy “has a potential to be used in fat cells and cellulite reduction as well as in the improvement of blood lipid profile without any significant side effects.” The subcutaneous fat layer was reduced from 12mm before treatment to 8mm after.
