Red, Blue, Green, and Yellow light therapy all use different wavelengths of light to create
specific effects in the skin and body. Each color penetrates to different depths and is used for
different goals. Here is a clear breakdown:
Red Light Therapy (620–700 nm)
Purpose: Healing, anti-aging, muscle recovery
Penetration: Deep (dermis and into muscle tissue)
Benefits:
- Stimulates collagen production to reduce wrinkles and fine lines
- Boosts cellular energy (ATP)
- Speeds muscle recovery and reduces inflammation
- Improves circulation and skin firmness
- Often used for joint pain, soreness, and injury recovery
Common Uses: Anti-aging facials, chronic pain relief, athletic recovery
Blue Light Therapy (400–500 nm)
Purpose: Acne and antibacterial treatment
Penetration: Shallow (surface of the skin)
Benefits:
- Stimulates collagen production to reduce wrinkles and fine lines
- Boosts cellular energy (ATP)
- Speeds muscle recovery and reduces inflammation
- Improves circulation and skin firmness
- Often used for joint pain, soreness, and injury recovery
Common Uses: Anti-aging facials, chronic pain relief, athletic recovery
Green Light Therapy (510–560 nm)
Purpose: Hyperpigmentation and calming
Penetration: Mid-level (epidermis)
Benefits:
- Targets melanocytes to help lighten dark spots and sun damage
- Evens skin tone and reduces redness
- Has a calming and relaxing effect on skin and the nervous system
- Helps with broken capillaries and sensitive skin
Common Uses: Dark spots, melasma, redness, rosacea, stress-related facial tension
Yellow (or Amber) Light Therapy (570–600 nm)
Purpose: Skin soothing and circulation support
Penetration: Moderate (closer to the surface)
Benefits:
- Reduces redness, swelling, and inflammation
- Helps with lymphatic drainage
- Improves circulation for a healthy glow
- Often recommended after more intense skin treatments to minimize downtime
Common Uses: Post-treatment recovery, rosacea, dull or devitalized skin
