It all starts with light.
Light therapy — also called photobiomodulation or low-level light therapy (LLLT) — uses specific wavelengths of visible light to stimulate skin healing and treat acne without chemicals or harsh medications.
Research shows that LED light therapy is effective for acne and other skin concerns:
A 12-week clinical study showed that blue + red light treatment led to a 76% reduction in active acne lesions compared to baseline. (Journal of Cosmetic and Laser Therapy, 2018).
A study in the British Journal of Dermatology found that dual-light therapy was significantly more effective than blue light alone for reducing inflammation and long-term recurrence.
NASA-funded research initially discovered that red light accelerates tissue repair — later adopted widely in dermatology.
🔵 Blue Light Therapy — “The Breakout Blocker”
Wavelength: ~405–450 nm
Kills acne-causing bacteria, reduces surface oil, prevents new breakouts Active acne, oily skin, surface blemishes.
How It Works:Blue light penetrates the upper layers of the skin and targets Cutibacterium acnes (formerly P. acnes), the bacteria responsible for inflammation.
The light triggers a photochemical reaction that causes these bacteria to self-destruct without harming surrounding tissue.
Key Benefits:
- Kills acne-causing bacteria (C. acnes).
- Reduces oil production by shrinking sebaceous glands.
- Prevents new breakouts when used regularly.
- Gentle on skin — no peeling or dryness like harsh topical treatments.
Best For:
- Whiteheads, blackheads, and small pustules.
- Oily or congested skin types.
🔴 Red Light Therapy — “The Skin Healer”
Wavelength ~620–700 nm
Reduces inflammation, speeds healing, stimulates collagen production Post-acne marks, redness, scars, anti-aging
How It Works:Red light penetrates deeper into the skin than blue light, reaching the dermis. It stimulates mitochondria in skin cells, boosting ATP production — giving cells more energy to heal and regenerate.
Promotes collagen and elastin synthesis, improving skin structure and resilience.
Key Benefits:
- Reduces inflammation & swelling from acne and blemishes.
- Speeds healing of irritated or damaged skin.
- Fades hyperpigmentation and post-acne marks.
- Boosts collagen production for smoother, firmer skin.
- Improves overall skin tone and texture.
Best For:
- Red, inflamed pimples.
- Acne scars and dark spots.
- Anti-aging and skin rejuvenation.
🔵🔴 Dual Light Therapy — “The Power Combo”
Utilizes both wavelengths at the same time for reduced treatment times
How It Works:ClearDot by Skinclear combines blue and red light for synergistic benefits:
Key benefits
- Blue light → Attacks acne bacteria at the source.
- Red light → Calms inflammation, heals tissue, and prevents scarring.
Why It Works Best:
Treating acne effectively requires both eliminating bacteria and repairing the skin barrier — a dual approach that single-wavelength devices can’t match.
Combination Blue + Red Tackles both cause and effect: clears bacteria + soothes skin Most effective for breakouts, blemishes, and healing
