Red Light Therapy

Low-level light support focused on skin quality, recovery, and overall wellness optimization.

What is red light therapy?

Red light therapy (RLT) is a treatment that uses low levels of red light to reportedly improve your skin's appearance, such as reducing wrinkles, scars, redness, and acne. It is also promoted for other medical conditions.

At this stage, there is ongoing research, many small studies, and broad discussion about effectiveness across different health uses. Some studies show promise, but full effectiveness has not yet been definitively established.

Other names used for red light therapy

  • Low-level laser light therapy.
  • Low-power laser therapy.
  • Non-thermal LED light.
  • Soft laser therapy.
  • Cold laser therapy.
  • Biostimulation, photonic stimulation.
  • Photobiomodulation and phototherapy.

How did interest in red light therapy evolve?

NASA first explored red light therapy for plant growth in space and later for supporting wound healing in astronauts. Over time, additional potential uses began to be investigated.

Red light is also medically used in photodynamic therapy, where low-power red laser light activates a photosensitizer drug to trigger a chemical reaction that destroys targeted cells. This method is used for some skin conditions and certain cancers.

Today, RLT is being studied (or used) for a wide range of conditions. The controversial point is not interest, but how strongly the available evidence supports each claimed benefit.

How does red light therapy supposedly work?

RLT is thought to act on mitochondria (the "power plant" of cells). With more available energy, cells may function more efficiently in processes linked to repair and regeneration.

In skin-related uses, RLT may help to:

  • Stimulate collagen production (structure, strength, elasticity).
  • Increase fibroblast production, which supports collagen formation.
  • Increase blood circulation to tissue.
  • Reduce inflammation in cells.

Skin conditions being explored

RLT is promoted for several common skin-related goals:

  • Improve wound healing.
  • Reduce stretch marks.
  • Reduce wrinkles, fine lines, and age spots.
  • Improve facial texture.
  • Support psoriasis, rosacea, and eczema care.
  • Improve scars and sun-damaged skin.
  • Improve hair growth in people with androgenic alopecia.
  • Improve acne.

Is red light therapy effective?

Most experts say the evidence is still developing. Current studies show potential in some conditions, but more high-quality trials are needed before most uses can be fully confirmed.

The strongest study design is a randomized, placebo-controlled trial, often compared against a standard treatment. Many RLT studies so far have had small sample sizes or other limits, which is why larger studies are still needed.
