The blue light wavelength dermatologists use for acne. Now at home.
Breakout bacteria produce porphyrins — molecules that absorb light, with peak absorption at 415nm. Persephone delivers exactly that wavelength at a published 30 mW/cm², in 10-minute hands-free sessions.
- Targets the bacteria associated with breakouts — no harsh topicals, no downtime
- Pairs 415nm blue with 633nm red for post-blemish redness in one Clarity Mode
- 186 LEDs (744 chips) — 2–3x the coverage of typical drugstore masks

Why 415nm — and not just any blue light
Not all blue light is equal. The bacteria associated with breakouts produce porphyrins — light-sensitive molecules with peak absorption at 415nm. That's the wavelength used in professional dermatology phototherapy, and it's the wavelength Persephone delivers.
415nm light reaches the skin
186 LEDs deliver a published 30 mW/cm² — within the output range used in phototherapy studies. Most brands don't publish their output. We do.
Porphyrins absorb the light
Research suggests 415nm light interacts with the porphyrins produced by breakout-associated bacteria — no topical required.
633nm red follows up
Clarity Mode pairs blue with red light, which may help with the look of post-blemish redness. Two concerns, one 10-minute session.
If a mask won't publish its output, ask why
Light therapy only works if enough light actually reaches your skin. Most drugstore masks list 50–150 LEDs and no irradiance number at all. Here's how Persephone compares — spec for spec.

Persephone is soft medical silicone with a secure strap — hands-free, cordless, and comfortable enough that you'll actually use it. Because a mask that sits in a drawer doesn't help your skin.
Weeks 1–2
Build the habit: 10–20 minutes in Clarity Mode, 3–4x per week, on clean dry skin.
Weeks 4–8
Studies on blue light phototherapy show improvements in the appearance of inflammatory blemishes with consistent use over 4–8 weeks. Results vary by individual.

2,000+ reviews. 4.8 out of 5.
From people who tried the serums, the spot treatments, and the TikTok hacks first.
"Less irritated" — that's the word
I was skeptical because it's cheaper than the big-name masks. But after 4 weeks my skin looked less irritated. That's the word — less irritated.
The first thing I've stuck with
I've tried every serum, every spot treatment, every hack on TikTok. Persephone is the first thing I've actually stuck with because it's effortless.
Finally, a mask I actually wear
I've bought three LED masks before this. They all hurt my nose or slipped off. The Persephone silicone actually fits. I wear it while I answer emails.

Blue light needs consistency, so we give you more than three months — through the full 4–8 week window studies describe, and then some. If your skin doesn't look better, send it back for a full refund. No forms. No questions.
Fair questions, straight answers
Does blue light actually do anything for breakouts?
Multiple studies on 415nm blue light phototherapy have shown improvements in the appearance of inflammatory blemishes. The proposed mechanism: breakout-associated bacteria produce porphyrins, which absorb light with a peak at 415nm. Results vary by individual and require consistent use over 4–8 weeks — which is exactly why the guarantee runs 100 days.
How is this different from a $40 mask on Amazon?
Two numbers most masks won't show you: LED count and irradiance. Persephone has 186 LEDs (744 chips) versus a typical 50–150, and publishes its output — 30 mW/cm² measured at skin level. It's also FDA 510(k) cleared (K250830), which most drugstore masks are not. If a brand won't tell you how much light reaches your skin, there's usually a reason.
Is it FDA approved?
Persephone is FDA 510(k) cleared (K250830), meaning the FDA determined it's substantially equivalent to legally marketed predicate devices for at-home LED phototherapy. "Cleared" is the correct term for this device class — "approved" applies to a different regulatory pathway. We'd rather use the accurate word.
Is it safe for my skin?
Persephone is designed for skin types I–VI, with soft medical silicone, integrated silicone eye protectors, 3 dimming levels, and a 10-minute auto-shutoff. No downtime, no harsh chemicals. If you're under dermatological care or take photosensitizing medication, check with your provider first.
How long until I see something?
Plan on 10–20 minute sessions, 3–4x per week. The studies describe a 4–8 week window with consistent use, and individual results vary. Set a realistic expectation, stick with it, and let the 100-day window be your judge.
What's in the box?
The Persephone LED mask (186 LED array, 744 chips), a controller with 6 built-in modes, USB power cable, adjustable straps, silicone eye protectors, a travel pouch, and a quick-start guide. Plus a 1-year warranty.
