Peer-reviewed research, lab-measured irradiance and dermatology-grade guidance — so you can tell the difference between marketing and medicine before you spend £2,000.
Red, near-infrared & blue light — wavelengths, irradiance and what actually penetrates skin.
Barrier, collagen, ageing biology — the fundamentals behind every claim.
Wrinkles, under-eye laxity, pigmentation, acne — evidence by problem.
Independent, spec-by-spec comparisons of premium LED masks & tools.
How to judge an LED mask on irradiance, wavelength, coverage and real certification — not marketing. With a fully-referenced comparison table.
Most beauty-device marketing quotes impressive numbers with no source. We do the opposite: every efficacy figure links to a citation, and every irradiance reading is checked against an accredited lab report — by reference number.
If a claim has no published source, it doesn't appear on this site.
Irradiance (mW/cm²) verified against SGS / accredited testing.
Where we're commercially connected to a product, we say so — clearly.

"More LEDs always means a better mask."
Diode count means little without measured irradiance and the right wavelengths reaching skin. A poorly-specced 1,000-LED mask can under-deliver versus a well-engineered one. Here's how to read the specs →
One carefully-researched email: a new study decoded, a myth dismantled, and one device worth knowing about. No hype, no daily spam.
