RED LIGHT THERAPY

Red light therapy (RLT), also known as photobiomodulation (PBM), uses specific wavelengths of red (around 660 nm) and near-infrared light (around 850 nm) to stimulate the mitochondria—the “powerhouses” inside your cells. This helps increase cellular energy (ATP), which supports the body’s natural healing, repair, and recovery processes.

Potential Benefits

Healthier, younger-looking skin

• Stimulates collagen and elastin production
• Helps reduce fine lines and wrinkles
• Improves skin tone, texture and elasticity
• May reduce redness and signs of sun damage
• Can improve the appearance of scars and stretch marks 

Faster healing & tissue repair

• Supports wound healing
• Encourages tissue regeneration
• Improves circulation and oxygen delivery to cells
• May accelerate recovery after injury or surgery 

Reduced inflammation & pain

• Helps decrease inflammation throughout the body
• May reduce joint and muscle pain
• Has shown benefits for conditions such as osteoarthritis and fibromyalgia in clinical studies 

Muscle recovery & performance

• May reduce post-exercise muscle soreness
• Supports faster recovery after training
• Can improve muscle function and reduce fatigue when used consistently 

Hair growth

• May increase hair density and thickness in people with androgenetic (pattern) hair loss.
• Often used alongside other hair restoration treatments. 

Supports certain skin conditions
Research suggests benefits for:

• Acne
• Rosacea
• Psoriasis
• Eczema
• Sun-damaged skin

Scientists are also investigating red and near-infrared light for:

• Cognitive function and brain health
• Healthy ageing
• Nerve repair
• Chronic fatigue
• Recovery after neurological injury

Early results are promising, but larger, high-quality clinical trials are still needed before these uses become established treatments.

For Red light to be effective the skin must be exposed to the light.  It will not work through clothing.  
If you only require a certain area to be treated you can just wear/cover the rest of your body with dark/thick clothing.
