Most skin tools are sold on packaging and TikTok. We grade them the way we grade everything — on the actual evidence: the wavelength, the dose, and whether controlled studies show they do anything. One category earns an A. Most don't. Here's the honest verdict.
See the grades ↓Controlled human trials on the mechanism — not a brand-funded "study," not a before/after in good lighting.
The right wavelength at enough intensity for long enough. The same "dose matters" test we run on every serum — most tools quietly fail it.
A real change in the skin, or a temporary de-puff that's gone by lunch? We say which.
We grade the category on the science. The fact that most score low is the point: it's how you know the A means something.
The one with real, controlled-trial evidence: red + near-infrared light measurably increases dermal collagen. But only at the dose — most cheap masks underpower it. Wavelength and irradiance are everything.
Decent evidence for mild breakouts (it kills acne bacteria). Not an anti-aging tool, and often padded into LED masks to inflate the LED count.
A real but temporary lift — small studies show modest contouring while you keep using it, several times a week, forever. The "boosts collagen / ATP" claims are weak. Maintenance, not magic.
A mild cleansing benefit, easy to overuse. Fine, not transformative — and rough on a compromised barrier.
Thin evidence. Mostly a tingle and the smell of ozone.
Feel wonderful. De-puff for about an hour via lymphatic drainage. No evidence they change your skin long-term — a nice ritual, not a treatment.
A gimmick with a great publicist. Pretty on a shelf; does nothing measurable.
Grades reflect the published evidence for each category at typical consumer doses — not any single product. "Cosmetic appearance" benefits only; nothing here diagnoses or treats a condition.
Run the same dose-and-receipts rubric on the mask you own (or are eyeing) and get an honest A–F grade.
We lead with the category that earns an A — independently dose-verified before it ships — and we're honest that the second is a temporary lift, priced like what it is, not like a miracle.

$149 · masks we graded ran $350–470
Flexible silicone, dual 633 nm + 830 nm, the clinically-relevant dose — independently lab-measured before it ships, with the report published. The same physics as the $400 names, at a third of the price, because you're paying for the light, not the logo.
Built to order — waitlisters get the drop and the founder price first. Ships ~6–8 weeks; full refund anytime before it ships (we never sit on dead stock), plus 30-day money-back once it arrives. It only gets built once enough of you want it and it passes its independent dose test.

$129 · ZIIP & NuFACE are $385–399
A genuine, temporary lift — we won't pretend otherwise. Good for a pre-event contour and a habit you'll keep up. Honestly graded C+, priced like what it is, not like a miracle.
Built to order — waitlisters get the drop and the founder price first. Ships ~6–8 weeks; full refund anytime before it ships. Honest note: microcurrent is a temporary lift — a real device at a fair price, not a miracle.
If it doesn't perform to the spec we published, send it back for a full refund — and cancel a built-to-order unit anytime before it ships. The published evidence is what lets us stand behind it that hard.
Every grade traces to published studies, the named active, and its dose — read the full methodology. Our own products are independently verified on the same public rubric, never graded by us.
30-day money-back, no hassle — and a full refund anytime before a built-to-order unit ships. We never sit on dead stock; you never sit on a product you regret.
We design and spec it; it's built by a vetted manufacturer and independently tested before it ships. We disclose plainly that we sell our own product — right here on the page.
Fair question, and the honest answer is the whole reason you can trust the grades. We hold ourselves to the same firewall we use for everything:
