It’s used to treat some skin conditions, including skin cancer and psoriasis, acne and warts and other types of cancer. Now, RLT is being investigated (or already in use) for treating a wide array of health conditions. What’s confusing — and controversial — is the effectiveness of the treatment for the purposes it’s being promoted. Red Light Therapy, also known as low-level laser therapy (LLLT), uses low energy light emitting diodes (LEDs) to stimulate cell function. The Red light penetrates the skin to a depth of 8-10mm. Once absorbed, the light energy is converted to cellular energy. Certain wavelengths of light enhance the functioning of mitochondria, which takes in Red light therapy has been widely studied as relief for permanent hair loss sufferers. Clinical trial after clinical trial supports RLT as a safe, painless, and effective treatment to promote proper hair growth. Here are a few of them: Hair Growth Increases 37%. One study, conducted in 2014, involved 42 women aged 18 to 60 with androgenetic Red light therapy is also referred to as low-level laser therapy (LLLT) or photobiomodulation therapy. It is an increasingly sought-after non-invasive treatment which harnesses the power of red Red light therapy is nontoxic, noninvasive, and considered safe for all skin types. You do not have to use any harsh topical substances or heat, both of which can irritate or burn the skin. Red light treatment does not use ultraviolet (UV) light, which has been linked to skin cancer. Shining near-infrared light on the tumor sites led to a reduction of fluorescence from cancer-tagged cells, indicating the treatment worked well as an anti-cancer strategy. Sato and his colleagues What it does. Low-level laser therapy — also referred to as red light therapy and cold laser therapy — irradiates photons into scalp tissues. These photons are absorbed by weak cells to Red light is known to have a mitogenic effect based on its ability to activate cell division at certain spectral and dose ranges in vitro. 7 – 9 We are aware only of two studies on the effects of LLLT on cancer. 10, 11 Revazova demonstrated the acceleration of tumor growth by 633 nm laser irradiation at 3.5 J/cm 2 three times per week for 2 week rPEsZm.
