LED therapy is one of the few aesthetic treatments where the mechanism is well-understood at a cellular level and the evidence base is genuinely robust. Specific wavelengths of non-thermal light are absorbed by chromophores in skin cells; the same mechanism that drives photosynthesis in plants, applied to human tissue. The result is increased mitochondrial activity, accelerated cell turnover, reduced inflammation, and stimulated collagen production; without any heat, any damage, or any downtime.

At House of Skincare on Yas Island, Abu Dhabi, Dr. Khadija Al Zaabi, Consultant Dermatologist, integrates LED therapy into treatment programmes as both a standalone modality and a post-procedure healing accelerator. Wavelength selection is clinically directed; not all wavelengths are appropriate for all concerns.

WHY HOUSE OF SKINCARE FOR LED THERAPY

LED therapy’s effectiveness depends on wavelength, irradiance, and treatment duration; not just exposure to light. The right wavelength for active acne (415 nm blue light) is different from what is needed for post-laser recovery (830 nm near-infrared). Dr. Al Zaabi selects the appropriate protocol based on your skin concern and how LED integrates with other treatments in your plan.

HOW LED THERAPY WORKS

Different wavelengths penetrate skin to different depths and trigger different biological responses; a process called photobiomodulation. Light energy is absorbed by cytochrome c oxidase in cell mitochondria, increasing ATP production and activating intracellular signalling pathways that stimulate repair, collagen synthesis, and anti-inflammatory responses. Critically, LED produces no heat and no structural damage; all effects are photochemical, not thermal.

WAVELENGTHS AND THEIR EFFECTS

Blue light (415 nm): Activates porphyrins produced by Propionibacterium acnes, generating reactive oxygen species that destroy the bacteria. First-line adjunctive treatment for active inflammatory acne.
Red light (630–660 nm): Penetrates the dermis to stimulate fibroblasts and collagen synthesis. Anti-inflammatory. Used for anti-ageing, rosacea, and post-procedure recovery.
Near-infrared (830 nm): Deepest penetration; reduces inflammation at tissue depth, accelerates wound healing, improves circulation. The standard choice after ablative laser or microneedling.
Yellow light (590 nm): Reduces redness, improves lymphatic drainage, calms reactive skin.

WHAT IT TREATS

– Active acne and post-acne redness
– Rosacea and chronic facial redness
– Post-procedure skin: accelerates recovery after laser, microneedling, and peels
– Fine lines and skin dullness
– Sensitive and reactive skin conditions

HOW MANY SESSIONS?

Standalone course: 6–10 sessions, 1–2 per week
Post-procedure add-on: 1–3 sessions immediately following treatment
Maintenance: monthly sessions once the primary concern is under control
