Results of Red Light Therapy

Red light therapy is used in many cases. This has been made possible by many clinical studies that have demonstrated the visible results of red light therapy. Below are some illustrative examples of photographic results before and after such studies.

Reduction of fine lines

[1] A randomized controlled trial was conducted in Germany in 2012 on 136 volunteers on the effects of light therapy on age-related changes in facial skin.

Collagen increase

In the same study [1] an ultrasound scan showing collagen density in the skin was done.

Acne treatment

Red light therapy is already actively used to treat acne, as there have been many studies proving its effectiveness. [2] One such study is a randomized, blinded clinical trial conducted in 2007 on 28 volunteers in Korea

Scar healing

[3] In 2010, a study was conducted on the effectiveness of using RLT as a prophylactic method to alter the wound healing process. The photographic results show a marked difference between the treated and control sides.

Hair loss treatment

Red light therapy increases the amount of hair by transforming the activation of down or intermediate follicles. This proves it a randomized double-blind clinical trial on 128 men and 141 women with typical alopecia [4].

Lose weight

RLT, under certain conditions, promotes a decrease in body volume. This change is due to the reduction in fat, not to the movement of fluid or fat through the body. [5] One study of the effects of light therapy was conducted back in 2009. According to its results, participants in the experimental group had an overall decrease of -3.51 inches, while the placebo group had a decrease of -0.684 inches.

Cellulite treatment

In addition to its effect on fat reduction, RLT combined with exercise has the additional effect of improving body aesthetics and aiding in the treatment of cellulite [6].
