A red light therapy (RLT) bed works by emitting specific wavelengths of red (630-700nm) and near-infrared (700-850nm) light to penetrate the skin and stimulate cellular repair, collagen production and other therapeutic benefits – without UV radiation or tanning effects.
How it works: The bed contains multiple LED panels that deliver concentrated red and near-infrared light.
Unlike tanning beds (which use UV lamps), RLT beds use non-thermal, non-damaging light.
Red light (630-700 nm) → Absorbed by skin cells (fibroblasts, mitochondria).
Near infrared (700-850 nm) → Deeper penetration into muscles, joints and bones.
Light energy increases ATP (cellular energy) production in mitochondria.
Triggers collagen & elastin synthesis (anti-ageing, wound healing).
Reduces inflammation and increases circulation.
Therapeutic effects Skin health (reduced wrinkles, acne, scars).
Pain relief (muscle recovery, arthritis, joint pain).
Hair growth (stimulates follicles).
Mood & sleep (may help circadian rhythms).
Key differences from sunbeds Feature Red light therapy bed Sunbed Light type Red/NIR (no UV) UVA/UVB (harmful UV) Purpose Healing, anti-ageing tanning Tanning effect? No Yes Cancer risk None Duration of session 10-20 mins 5-15 mins What to expect from a session No goggles required (unlike UV tanning).
Warm, glowing light (no burning or heat).
Frequency: 2-5 sessions/week for best results.
Who should use it?
People seeking skin rejuvenation (acne, wrinkles, scars).
Athletes for faster recovery.
Chronic pain sufferers (arthritis, back pain).
Pro Tip: For best results, combine RLT with topical antioxidants (vitamin C serum) and use consistently.
