What is Red Light Therapy?

Red light therapy (RLT) uses low levels of red light to potentially improve skin appearance by reducing wrinkles, scars, redness, and acne. It's also being explored for other medical conditions. Ongoing research and small studies suggest promise, but the full effectiveness of RLT is still being determined.

Other names for red light therapy include:

• 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

Evolution of Red Light Therapy

NASA initially experimented with red light therapy for plant growth in space and wound healing in astronauts. Its medical use is now accepted in photodynamic therapy, where low-power red laser light activates a photosensitizer drug to treat conditions like skin cancer, psoriasis, acne, and warts (NASA Study).

How Does Red Light Therapy Work?

RLT is thought to enhance the function of mitochondria, the "power plants" of cells. By absorbing light wavelengths, cells may work more efficiently, repairing skin, boosting cell growth, and enhancing rejuvenation.

Potential benefits for skin health include:

• Stimulating collagen production
• Increasing fibroblast production
• Improving blood circulation
• Reducing inflammation (Source)

Who Should Avoid Red Light Therapy?

Who should not use red light therapy? People who take medications that increase their skin or eye sensitivity should not use red light therapy. People who have a history of skin cancer or eye disease should speak with their doctor before using red light therapy.

Skin Conditions Treated with Red Light Therapy

RLT is being used to treat various skin conditions:

• Wound healing
• Reducing stretch marks
• Minimizing wrinkles, fine lines, and age spots
• Improving facial texture
• Treating psoriasis, rosacea, and eczema
• Reducing scars
• Repairing sun-damaged skin
• Promoting hair growth in androgenic alopecia
• Reducing acne (Source)

Effectiveness of Red Light Therapy

Most experts agree that more research is needed to confirm the effectiveness of RLT for all claimed uses. While some studies show potential, larger, high-quality studies are required. Current evidence is promising but not conclusive (Source).

Safety of Red Light Therapy

RLT appears safe with no known side effects if used as directed. It is non-toxic, non-invasive, and gentler than some topical treatments. However, misuse could potentially damage skin or eyes. Long-term safety remains unknown. Consult a dermatologist or trained professional for guidance (Source).

At-Home Devices

Many RLT devices are available for home use. While generally safe, they may be less powerful than professional devices, potentially yielding less effective results. Always shield your eyes, follow instructions, and maintain the device properly. It's best to consult with a medical professional before starting treatment (Source).

Other Medical Conditions

RLT is being investigated for:

• Reducing chemotherapy side effects like oral mucositis
• Relieving pain and inflammation from conditions like ankle tendonitis, rheumatoid arthritis, carpal tunnel syndrome, and osteoarthritis of the knee
• Preventing recurrent cold sores from herpes simplex virus (Source)

While many other uses are touted online, there is no scientific evidence supporting RLT for weight loss, cancer treatment, cellulite removal, or mental health conditions like depression and seasonal affective disorder (SAD) (Source).
