Red light therapy (RLT) is a form of light therapy that is believed to work by stimulating the mitochondria in cells, which are often referred to as the "power plants" of the body. This extra energy is thought to help cells function more efficiently, leading to benefits such as improved skin health, wound healing, and reduced inflammation.
RLT is being promoted as a treatment for a variety of skin conditions, including wrinkles, fine lines, age spots, psoriasis, rosacea, eczema, and acne. However, at this point, there is not enough scientific evidence to support most of these claims. The majority of studies that have been conducted so far have been small in scale and have not included a placebo group, making it difficult to draw conclusions about the effectiveness of RLT.
In terms of safety, RLT is generally considered to be safe when used as directed. It is not toxic, invasive, or as harsh as some topical skin treatments, and it does not use cancer-causing ultraviolet light. However, there is still a lack of knowledge about the long-term safety of RLT, and if products are misused, there is a chance of skin or eye damage.
If you are interested in trying RLT, it is recommended that you see a dermatologist or qualified cosmetic therapist. They can help you determine if RLT is the right treatment for your skin condition and provide guidance on how to use the therapy safely and effectively.
