Our Science: Nine Technologies, Every Layer of Your Face
Nine technologies. One hand. Every layer of your face.
A firmer jawline, softer lines and clearer skin, from the surface down to the muscle.
Most devices give you one or two of these technologies; ours give you all nine, which is why we call them the most complete facial devices on the market.1
Ten minutes a day, at home, and every claim on this page is linked to the study behind it.
A drawer full of gadgets, and still a soft jawline.
Every device you have tried was probably good at one thing and silent on the rest.
A microcurrent wand talks to the skin cells and never reaches the muscle.
A light mask reaches the collagen layer and does nothing for the shape of your face.
A muscle stimulator moves the muscle and ignores the skin above it.
We refused to choose, so we spent thirty-nine years putting all of them, and the technologies that make them work together, into one hand.
Microcurrent, sometimes nanocurrent. Nothing for the muscle, nothing for the light.
Red light, sometimes blue. Nothing for the skin cells, nothing for the muscle, nothing for your serum.
A few of the nine, usually without the waveform engineering that keeps muscle work comfortable.
All nine, in one hand, made in Japan, every one FDA-cleared.
1. Based on our September 2026 review of leading home facial devices from NuFACE, ZIIP, FOREO, Therabody and Medicube; we found no other home device that combines all nine technologies on this page. Technology counts describe features, not results.
What do you see in the mirror?
Pick your worry and we will show you the technology built for it, and the study that says so.
Sagging usually starts in the muscles under your skin, which is a job for EMS.
5 · LiftLines live in the collagen layer, where red light has the best facial studies of anything here.
9 · SmoothBlue light targets the bacteria behind spots.
8 · ClearMicrocurrent, a current you cannot feel, talks to your skin cells.
4 · RefreshOur devices are designed for better serum absorption, starting with Infusion.
1 · InfusionYour face is built in layers, and each layer needs a different kind of help.
Think of it like a cake.
The icing is your skin, where lines, dullness and spots show up.
Under the icing is a spongy layer of collagen, where firmness and bounce come from.
Under that are the muscles, which give your face its shape.
Scientists who study ageing faces say the same thing: it happens in every layer at once, not just the skin (Cotofana, 2016).
So we built a technology for each layer, and this page walks you through all nine in order, from the surface down to the muscle, and finishes with the light.
Hover the layers. Simplified; real skin has more layers than a cake.
Think of your routine as a training day for your face.
Our devices are designed for better serum absorption, so the skin is fed before it works.
Nanocurrent and microcurrent wake the skin cells gently, with no contraction.
EMS works the muscles that hold your face up, with PDM and PDM++ keeping the session comfortable.
Blue and red light finish the session, for breakouts and for lines.
Tiny, gentle pulses briefly open microscopic doors in the surface of your skin, so more of your serum is absorbed, then let the doors close again.
The surface of your skin is a brick wall: dead cells for bricks, fats for mortar. Infusion is a doorbell that gets the wall to open a crack, just for a moment.
In 1993, scientists at MIT showed that short electrical pulses open temporary routes through the surface of the skin.
While the routes are open, up to ten thousand times more of a test molecule can pass through (Prausnitz, 1993).
Six years later the same trick was tried with a skincare ingredient, and it measurably increased how much vitamin C got into human skin (Zhang, 1999).
Infusion is a dedicated pass, not a bolt-on: it runs after the muscle work, when the skin is warm and the blood is flowing, with your serum already on.
It works with any water-based serum, so nobody sells you a bottle to make the device work.
Very few home devices carry an infusion technology at all; among the brands we reviewed, only one does.
"Supports absorption", not "deep delivery". We describe the science Infusion is built on; we have not yet measured how much of a named ingredient reaches a named depth with our technology, and the ingredient decides most of the outcome before anything is switched on.
Like charges repel, so a current can nudge a charged ingredient away from the device and into your skin.
The standard review of the field explains why the ingredient's charge, the formula and the current all matter (Kalia, 2004).
Twelve weeks, one side of the face vitamin C, the other side water, both pushed in by a small current. The vitamin C side lightened dark patches more (Huh, 2003).
We describe the science; we do not claim a directional push for every ingredient. Whether an ingredient moves depends on its charge, the formula around it and the current, so results for one ingredient do not transfer to another.
Your body already runs on tiny electrical signals, and nanocurrent speaks that language at a whisper.
If a microamp were a drop of water, a nanoamp would be a thousandth of that drop. Nanocurrent is the quietest voice in the room, and your cells still hear it.
Every cell in your body keeps a small electrical charge across its wall, and injured skin switches on its own faint field to guide repair.
Devices that reach into the nanoamp range have been used in wound clinics, where a report on 25 patients with wounds that had resisted other treatment described improvement (Lee, 2007).
Nanocurrent is usually sold as a device of its own; on ours it is the first setting of the same dial that ends at the muscle.
You can start at a whisper and, on the same handpiece, on the same evening, turn up to a workout.
No facial study has tested nanocurrent on its own yet, and no study shows nanoamps "speak to cells" better than microamps; we call nanocurrent what it is, the gentle floor of our range, not a magic setting.
A current a million times weaker than a muscle needs, and just enough for skin cells to notice.
Think of the current as exercise and your serum as nutrition. Microcurrent is the warm-up: it gets the skin cells moving before the muscles start work.
Skin cells listen to small currents, and the best proof comes from wound healing.
When seven studies with 337 people were pooled, adding microcurrent to normal wound care helped wounds close faster (Avendaño-Coy, 2022).
In a split-face study, the side treated with microcurrent showed less eye-wrinkle volume and denser skin, while the side treated with EMS showed more lift (Kwak, 2023). Different currents, different layers, the whole idea of this page in one study.
In an earlier study of 30 women, judges who did not know which photos were "before" and "after" scored wrinkles as improved after 30 sessions (Saniee, 2012).
Most microcurrent brands sell you a number of microamps; we engineer the waveform, because the shape of the signal decides what the cells do.
One 2025 laboratory study found a particular low-intensity signal reduced the collagen precursor skin cells make (Kang, 2025), which is exactly why the waveform matters more than the label.
And on a PureLift, microcurrent is the second setting, not the ceiling: the same dial keeps going to the muscle.
About "500% more ATP". You will see it on other boxes; it comes from rat skin in a lab dish in 1982, the real figure was 379%, and it vanished at higher currents (Cheng, 1982). Microcurrent does not move muscle and does not "drain" puffiness; for lift, keep going.
A stronger signal makes your facial muscles contract, like a workout without the effort.
Nobody expects one sit-up to change their body, but a few minutes a day, every day, is a different story. Same idea, same muscles, just on your face.
Muscles that get used grow stronger, and the face is no exception.
In the biggest study of its kind, 108 women used facial muscle stimulation every day for 12 weeks, and scans showed their cheek muscle got 18.6% thicker (Kavanagh, 2012).
12 weeks, daily use. The cheek muscle was measured by ultrasound, by people who did not know who had used the device, and the difference from the untreated group was clear at 6 weeks and clearer at 12.
In another study, the stimulated side of the face showed better elasticity, a sharper jawline angle and less sagging after 8 weeks (Omatsu, 2024).
Tested against a fake device, 6 weeks of stimulation made the jaw muscle thicker and stronger in adults over 65 (Chang, 2020).
CT scans in a third study showed the muscle around the eye growing thicker on the stimulated side (Okuda, 2026).
Those muscles sit in a stretchy sheet called the SMAS, the layer surgeons tighten in a facelift, and that sheet loosens with age (Okuda, 2019); working the muscles is the one non-surgical way to reach it.
Real muscle-level current: up to 9 milliamps, thousands of times more than a microcurrent wand, in the kilohertz band engineered to engage the muscle with less discomfort.
Eight muscle levels, because every face has three thresholds: the point you feel it, the point the muscle moves, and the point it hurts, and the gap between them changes with skin thickness, hydration and which muscle sits underneath.
Eight muscle levels · find "it moves", stay below "it hurts"
Eight steps let you find, for each area, the level that is above "the muscle moves" and below "this is uncomfortable", which is the only dose that matters.
And the same technology has run in professional treatment rooms since 1987, under other names, in more than 500 spas.
It is exercise, not surgery. One session is one repetition, results build with use and fade without it, and EMS does not rebuild fat, bone or the SMAS itself; the studies above used their own devices, so they show what facial muscle stimulation can do, not a promise about you.
Instead of one steady signal, PDM moves across 361 frequencies between 1,370 and 1,730 Hz, so your muscles keep answering.
The idea is well tested on the body.
When 22 studies were pooled, a changing signal produced more muscle work with less tiredness than a fixed one (Cavalcante, 2026).
In a blind test, a randomly changing signal was harder to get used to than a steady one (Avendano-Coy, 2019).
Most muscle stimulators, including the professional ones, run one fixed frequency.
PDM is our own architecture, and it runs on every PureLift, from the first muscle level to the last.
Fair warning: not every study agrees, and one found a changing pattern tired muscle just as much (Papaiordanidou, 2014); PDM is designed to reduce "getting used to it", and we never say your muscles cannot adapt.
Engineered for, not proven to. No branded waveform, ours included, has yet been tested on a face against a plain fixed pattern, so we say "engineered for a smoother feel" and nothing more.
Blue light makes tiny molecules inside spot bacteria turn on their own host.
Spot bacteria carry molecules that react to blue light like a match to a strike-strip. Shine the right blue on them, and the reaction happens inside the bacteria, not in your skin.
The bacteria involved in acne make molecules called porphyrins.
Porphyrins absorb blue light, and when they do they become reactive and damage the bacteria from the inside; that part is chemistry, not marketing.
There may be a second route too: in skin cells with no bacteria present at all, blue light lowered a key sign of inflammation by up to 82% (Shnitkind, 2006).
Six studies of home LED devices, pooled in 2025. People with mild-to-moderate acne had more improvement in spots than the comparison groups, with no serious side effects (Ershadi & Barbieri, 2025).
To be fair, an older review of 14 studies found the average benefit less convincing (Scott, 2019), so we say "good short-term signs in controlled studies", not "cured".
Our blue is 465 nm, the exact wavelength in our FDA clearance for mild-to-moderate inflammatory acne, so the light on your face is the light that was cleared.
And the light runs while the muscle work happens, so a session that lifts is also a session that clears; no mask, no second appointment.
For mild-to-moderate acne only, never severe or cystic and never over the eyes; blue light can leave dark marks on medium and deeper skin tones (Duteil, 2014), so start on a low setting, and most acne studies used a slightly different blue (405 to 420 nm) while 465 nm is the one in our clearance.
Skin cells absorb red light and respond by doing their repair work a little better.
Think of a plant on a windowsill. The right light, on a regular schedule, and it does more of what it already knows how to do. Your skin cells are the plant, and red light is the window.
The classic test gave 76 people real red light, near-infrared, both, or a fake lamp, on one side of the face, twice a week for four weeks.
Wrinkles softened and skin got bouncier on the treated side, and tiny skin samples showed more collagen and more of the stretchy fibres that keep skin firm (Lee, 2007).
Given a real or a fake red-light mask for 12 weeks, without knowing which. Crow's feet improved more in the real-light group, and the improvement was still there four weeks after they stopped (Park, 2025).
Aged 45 to 60, real light versus fake. Measured wrinkle lengths and the women's own satisfaction favoured the real light, and twice a week worked as well as three times (Bragato, 2025).
Our red is 634 nm, the exact wavelength in our FDA clearance for the treatment of wrinkles.
Run red and blue together and the light reads purple, for skin that has breakouts and early lines at the same time; two jobs, one pass.
And because the light lives on the same handpiece as the muscle work, the collagen layer gets its session on the same ten minutes the muscles get theirs.
About the "36% fewer wrinkles" you have seen on other sites: it is the best number from the best group in that 2007 study, measured against their own starting point, not the average gain over the fake lamp; real results are smaller, slower and depend on regular use, and no facial study has shown red plus blue beats either on its own.
The most complete facial devices on the market. Here is what that means.
It does not mean nine buttons.
It means that for every layer of your face there is a technology that speaks its language, and that all of them were engineered by one team, in one factory, to run on one handpiece, in one ten-minute session.
A microcurrent wand gives you two of the nine; a light mask gives you two; the most ambitious multi-mode devices give you four or five, usually without the waveform engineering that makes muscle work comfortable.1

More technologies means more of your face addressed; it does not mean the technologies amplify each other, and no study has tested our nine together, so we say complete, and we do not say synergy.
One routine. Ten minutes. Every layer.
You do not need to understand the layers to use them, because the order does the thinking for you.
Start on the gentle levels (3 and 4), then turn up only to comfortable and watch the muscles engage along the jaw, cheeks, brow and neck (5, 6 and 7).
Apply your serum, then the infusion pass (1 and 2), designed for better absorption, helps it get past the surface.
Blue for spots, red for lines, both for both (8 and 9); a few minutes, a few times a week, and the light can run while you work.
Honest timelines, from the studies.
Every face is different, so these are the timeframes the research used, not a promise about yours.

What we will not promise you.
The technologies with the best evidence make the smallest claims, and so do we.
We say
- Our EMS works the muscles under your skin, for a firmer, more defined, more lifted look with continued use.
- Our red and blue light are FDA-cleared for wrinkles and for mild-to-moderate acne.
- Our nanocurrent and microcurrent support fresher, smoother-looking skin.
- Our devices are designed for better serum absorption, helping your serum get past the surface.
- Our devices are the most complete on the market: nine technologies, one hand, every one FDA-cleared, made in Japan.
We don't
- "Facelift." "Permanent." "Reverses sagging."
- That we rebuild bone, fat or the deep tissue under your skin.
- That any study on this page used our technology, because none did.
- "500% more ATP." "Muscles never adapt." "Drains lymph."
- That our light beats every mask, that a serum is "activated", or that nine technologies work better together than apart.
There is no study comparing our technology head-to-head with any named brand; everything above comes from a 231-source review of the research, last checked 27 August 2026.
Thirty-nine years. One country. Five hundred rooms.
You may have met our technology already, under another name, in a good spa; we have been building facial stimulation in Japan since 1987, and nothing else.
