Most facial device reviews describe how something felt rather than what it did, and a few simple checks will tell you which kind you are reading before you spend $400 or more.
This article gives you the checks worth running on any review, ours included, such as:
- What makes a before and after photograph worth trusting
- The five details a review must name before its verdict means anything
- Why the same device can be described as gentle and as intense
- How to tell a study that tested a device from one that tested a category
- Which specification numbers actually predict what a device can do
and many more!
By the end you will be able to read any device review, including this brand's own, and know how much weight it deserves.
Key Points:
A photograph taken right after a session shows the temporary effect, not the lasting one, so ask when it was taken.
A review that does not name the exact model, the level used and the serum is describing a feeling rather than a device.
Strength, the maximum output current at 500 ohms, is the number that decides whether a device stays at the skin or reaches the muscle.
Category research shows what a technology can do; it never shows what one brand's device did for the person writing.
No clinical trial has tested a PureLift device, and we say so in every article rather than borrowing someone else's results.
Spend an evening reading facial device reviews and you will notice the same shape repeating: a person, a device, six weeks, two photographs and a verdict.
Some of those reviews are careful and useful, and some are a feeling written up as a finding, and the difference is almost never the reviewer's honesty.
It is the detail they left out, and once you know which details to look for, sorting one from the other takes about a minute.
Start with the photographs
A before and after pair is only evidence if the two images differ in one thing, which is the device.
Ask whether the lighting, the camera distance, the head position, the expression and the makeup match, because a face photographed from slightly below with a softer light will look lifted whatever happened in between.
Then ask the question almost nobody answers, which is when the second photograph was taken.
Three minutes on each side with a current device produces a real, visible change straight away, a fresher and more lifted look, because the muscles have worked and blood is flowing, and it fades over the following hours.
A photograph taken minutes after a session is documenting that temporary effect honestly enough, but it tells you nothing about where the face will be in twelve weeks, and a review that blurs the two is overstating its case.
The five details that make a review readable
The exact model, because a brand's entry device and its flagship can differ by a factor of two in output, and a review of one is not a review of the other.
The level used, because most devices have a range and the experience at the bottom of the dial has nothing in common with the experience at the top.
The serum or gel on the skin, because the conductive layer changes how much current actually arrives, and a dried-out layer will make any device feel weak.
How often and for how long, because consistency is the variable that separates people who see change from people who do not.
And what else changed in the same period, because a new retinoid, a facial, better sleep or a course of treatment will all show up in the second photograph.
Why the same device gets opposite reviews
Read enough reviews of one device and you will find one person calling it barely noticeable and another calling it too strong.
Both can be telling the truth, because everyone has three separate thresholds: the point you feel the current, the point the muscle moves, and the point it hurts.
A review of kilohertz-frequency stimulation describes exactly that separation (Ward 2009), and the gaps between the three shift with skin thickness, hydration, placement and how much serum is on the face.
So one person's level 4 is another person's level 6, and a reviewer describing their own comfort is not describing the device.
How to read a study a brand cites
Brands cite research constantly, and the useful question is never whether the study is real, it is what the study actually tested.
Ask first whether it tested that brand's device or the technology in general, because almost all of them tested the technology.
The largest facial trial of its kind had 108 women use facial muscle stimulation daily for twelve weeks, with ultrasound measuring an 18.6 percent increase in cheek-muscle thickness (Kavanagh 2012), and it used its own device rather than any product on sale today.
Ask second whether there was a control group, because a double-blind trial against a dummy device that looks identical (Chang 2020) is worth far more than a study where everyone knew what they were getting.
Ask third whether the intervention was one thing, because a study combining stimulation with light and iontophoresis cannot tell you which part did the work, and one widely quoted example carries a 2026 correction disclosing that two authors worked for the device maker.
None of that makes such research worthless, and it does mean a brand quoting it is telling you what its technology category can do, never what its device did for you.
Which numbers mean something
Strength is the maximum output current, measured into a 500 ohm load, and it is the one figure that predicts what a device can reach.
Watch the units, because a device quoted at 680 microamps and one quoted at 7 milliamps are not in the same territory, since 7 milliamps is 7,000 microamps.
Microcurrent devices publish figures in the hundreds of microamps, which is enough to work at the skin, and crossing into the thousands is what fires the nerve that moves a facial muscle.
Be sceptical of any brand claiming an advantage of a thousandfold or more, because a claim on that scale is usually comparing one unit against another rather than one device against another.
And treat a missing number as its own kind of answer, since several well-known brands publish no output figure at all and leave you to find it in their FDA clearance summary.
What FDA clearance does and does not tell you
A 510(k) clearance means the device passed a safety and equivalence review for a stated intended use, and it is a genuine signal worth checking.
It is not FDA approval, it is not proof that any marketing claim is true, and it says nothing about whether one cleared device outperforms another.
What a clearance document does give you is a number the brand cannot soften, which is why the output figures in our own articles cite theirs: K190269 for Face, K230506 for Pro and Pro Edition, K221443 for Pro Plus and K243587 for GLOW.
If a brand tells you a device is cleared but will not tell you what it is cleared for, that gap is the finding.
Turn the same checks on us
No clinical trial has tested a PureLift device against anything, and every article we publish says so.
What we can tell you is documented: every model runs nanocurrent at level 1, microcurrent at level 2, EMS from level 3 to level 10 and an Infuse pass for your serum, at up to 7 milliamps on Face and Pro, 7.7 on Pro Edition and 9 on Pro Plus + and GLOW, all at 500 ohms and always written as up to.
Where we cite research it is category research, quoted as category research, and where a claim would need a study we do not have, we say what we do not know instead.
Infuse is the clearest example: it is built on the delivery science of electroporation (Prausnitz 1993), and we say it supports absorption rather than promising that a named ingredient reaches a named depth, because no product-specific penetration study exists.
Hold this article to the same standard you would hold any other, and if a paragraph here fails one of the checks above, it deserves the same discount.
A short reading routine
Read the specification before the verdict, because the numbers survive rewriting and the adjectives do not.
Read the disclosure, which does not invalidate an opinion but does tell you which way to lean when the review is glowing.
Read what the reviewer says they do not know, because a review that admits a limit is usually more careful about everything else.
Then look for the same device reviewed by someone with your skin, your routine and your patience, since that person's account will predict your experience better than any figure.
For what the levels actually feel like, read what a PureLift session feels like, and for a worked example of a price-matched comparison, read PureLift Face against FOREO BEAR 2.
Model figures verified on 8 September 2026 against the PureLift LAB store and FDA records K190269, K230506, K221443 and K243587. Every model runs nanocurrent, microcurrent, EMS and Infuse, and no clinical trial has tested a PureLift device.
Two related questions come up often alongside this one, and we have answered both in full: which brands actually carry microcurrent, and what we would tell you not to buy.
