What is red light therapy?
Red light therapy (RLT) is a therapeutic technique that uses red low-level wavelengths of light to treat skin issues, such as wrinkles, scars, and persistent wounds, among other conditions.

Red light therapy can help speed up the skin’s ability to heal by increasing blood flow to the area helps speed up the body’s ability to repair itself naturally.
Red light is thought to work by producing a biochemical effect in cells that strengthen the mitochondria. The mitochondria are the powerhouse of the cell — it’s where the cell’s energy is created. The energy-carrying molecule found in the cells of all living things is called ATP (adenosine triphosphate).
By increasing the function of the mitochondria using RLT, a cell can make more ATP. With more energy, cells can function more efficiently, rejuvenate themselves, and repair damage.
RLT is different from laser or intense pulsed light (IPL) therapies because it doesn’t cause damage to the skin surface. Laser and pulsed light therapies work by causing controlled damage to the outer layer of the skin, which then induces tissue repair. RLT bypasses this harsh step by directly stimulating the regeneration of the skin. The light emitted by RLT penetrates roughly 5 millimeters below the skin’s surface.
With red light therapy, you expose your skin to a lamp, device, or laser with a red light. A part of your cells called mitochondria, sometimes called the “power generators” of your cells, soak it up and make more energy. Some experts think this helps cells repair themselves and become healthier. This spurs healing in skin and muscle tissue.
Red light therapy uses very low levels of heat and doesn’t hurt or burn the skin. It’s not the same type of light used in tanning booths, and it doesn’t expose your skin to damaging UV rays.
RLT is a straightforward procedure involving exposing the body to low wavelength red light. Low-level laser light therapy is another name for the process, though RLT may be more common.
This red light is natural and can penetrate deep into the skin, where the cells can absorb and use it.
As a study in the journal Seminars in Cutaneous Medicine and Surgery notes, mitochondria in the skin cells can absorb these light particles. This can help the cells produce more adenosine triphosphate, which is the energy source for all cells.
Many experts attribute the potential positive benefits of RLT to this function. With this extra energy, the cells may be able to respond better to damage and rejuvenate themselves.
