Red light therapy is commonly referred to as photobiomodulation. It was  accidently discovered by Endre Mester in 1967 at the Semmelweis Medical University in Budapest, Hungary. He noticed that laser light helped promote hair growth and wound healing in lab animals.  RLT works by repetitively exposing your skin to low levels of red and near-infrared light for a certain period of time. At low wavelengths, red light doesn’t generate heat and penetrates the skin between 1 and 2 millimeters . Red light  therapy (LED) treats various skin conditions and concerns, such as acne, fine lines and psoriasis. It comes in different types, including red light therapy and blue light therapy, which are sometimes used in combination.  Red light therapy is a non invasive treatment that enters the skin’s layers to improve the skin.  This red light exposure  produces a positive biochemical effect in your cells that strengthens the mitochondria, which is where the cell’s energy is created. RLT may do this by increasing the transportation of electrons, oxygen consumption, and your levels of adenosine triphosphate  (ATP).  In summary it increases blood flow, reduces inflammation, increases the levels of collagen and lastly increases the levels of fibroblast.   A fibroblast is a type of cell that is responsible for making the extracellular matrix and collagen.

 By increasing the energy of the mitochondria, cells may function more efficiently, as well as rejuvenate and repair themselves.  In the 1990s, NASA began studying LED’s effects in promoting wound healing in astronauts by helping cells and tissues grow.

Today, dermatologists and estheticians commonly use LED light therapy to treat a range of skin issues. Skin specialists often use LED light therapy together with other treatments, such as creams, ointments and facials, to give you the best results.     Red light therapy helps treat a variety of skin concerns and conditions, including the following.   Hair loss, eczema,  psoriasis, rosacea and sun damage just to name a few.  Research suggests that LED light therapy can help reduce and improve some skin conditions and issues. To see improvement in your skin, though, you need to have regular treatments.   Clinical  red light therapy uses more powerful strengths than at-home devices, which makes it more effective. With  portable devices, you likely won’t see dramatic anti-aging or acne-reducing results. You may over extended periods see minor improvements in your skin’s appearance.   

Red light therapy has been in use clinically for over 20 years and has proven to be safe and effective.
