LED Light Therapy: What Each Color Actually Does

LED light therapy has gone from dermatologist offices to living rooms — and for good reason. But with 7 colors available, it helps to know what you're actually getting.

Red (630–700nm) — Anti-Aging & Collagen

Red light stimulates collagen production, reduces fine lines, and improves skin elasticity. It's the most studied wavelength for skin rejuvenation.

Blue (415–445nm) — Acne Fighter

Blue light kills acne-causing bacteria (P. acnes) on the surface of the skin without harsh chemicals or drying effects.

Green — Pigmentation & Redness

Green light targets melanin-producing cells, helping to even out skin tone and reduce redness over time.

Yellow — Sensitivity & Rosacea

Yellow light soothes irritated skin and is particularly effective for those with rosacea or sensitive skin types.

Purple — Acne + Repair Combined

A combination of red and blue, purple light fights active breakouts while simultaneously promoting healing and reducing scarring.

Cyan — Inflammation & Swelling

Cyan light calms inflamed skin and helps reduce puffiness, making it great for post-procedure recovery.

White — Deep Penetration & Energy

White light penetrates the deepest, accelerating tissue metabolism and overall skin health.

Using a 7-color LED mask means you can rotate through wavelengths based on your skin's needs — or use combination modes for a full-spectrum treatment.
