Le Prof. Buschmann est l'une des principales autorités européennes en arteriogenèse — la croissance et le remodelage des vaisseaux sanguins induits par le flux — avec plus de 150 publications évaluées par des pairs et plusieurs brevets américains et européens sur des dispositifs stimulant la croissance des vaisseaux collatéraux par une thérapie contrôlée du taux de cisaillement. Ses recherches relient la stimulation mécanique et électrique à l'adaptation vasculaire, à la microcirculation et à la perfusion tissulaire.
Les contributions du Prof. Buschmann apportent aux lecteurs de PureLift LAB une perspective en biologie vasculaire qui complète notre expertise clinique, en physiothérapie et en anatomie chirurgicale — expliquant comment la stimulation EMS engage non seulement les muscles faciaux mais aussi la microcirculation qui les alimente, et pourquoi une administration intelligente est aussi importante au niveau du flux sanguin qu'à celui de la contraction musculaire.

Do not use either as your conductive layer, and keep acids on separate days, because low pH actives sting badly under current and may be driven deeper than anyone has studied.
This article sets out what to check before you start, such as:
- why low pH and electrical current are a bad combination
- the delivery question nobody has answered
- which form of vitamin C behaves differently
- the schedule that lets you use all three
- what to use as a conductive layer instead
and many more!
These are two of the most effective ingredient classes in skincare, and the point of this article is to keep them in your routine rather than to warn you off them.
Key Points:
L-ascorbic acid is formulated at a pH around 3.5, and acids sit between pH 3 and 4, which is where stinging under current becomes reliable rather than occasional.
Iontophoresis and electroporation are designed to increase ingredient delivery, so applying an active designed to exfoliate and then driving it deeper is an untested combination.
A compromised barrier lowers skin resistance, which makes a familiar dial setting feel stronger and makes the next session worse.
Separate days is the simplest approach, with acids on one night and the device on another, and vitamin C in the morning away from the session.
A plain water-based conductive gel with no actives is the correct conductive layer, and any active you want delivered is a separate decision from the one about conduction.
Why low pH and current do not mix
The formulation facts
L-ascorbic acid, the most studied form of vitamin C, is only stable and bioavailable at a low pH, typically around 3.5.
Glycolic, lactic and mandelic acids are formulated in a similar range, usually between pH 3 and 4, because that is where they exfoliate effectively.
Salicylic acid sits in a comparable range and is oil-soluble, which brings its own conduction problem.
What happens on the skin
An acidic product on intact skin produces a mild tingle for most people, which is familiar and usually harmless.
Add current and the sensation changes in character, becoming sharper and more localized rather than a general tingle.
The reason is that the current concentrates at points of best contact, and acidic product at those points produces a far stronger local response.
What people describe afterward is a sting that did not settle, which we cover in our article on stinging.
The delivery question nobody has answered
Iontophoresis uses like charges repelling to push charged molecules through the skin barrier, and electroporation briefly opens transient pathways through the outer layer.
Prausnitz and colleagues in 1993 demonstrated that applied electrical fields create those transient pathways, which is the published mechanism our Infuse pass is based on.
Both mechanisms exist to increase how much of a topical ingredient reaches living tissue.
Now apply that to an exfoliating acid, whose entire purpose is a controlled, limited interaction with the outer layer of skin. Nobody has studied what happens when you drive one deeper, and until someone does, the sensible position is not to find out on your own face.
The same reasoning applies to retinoids, which we set out in our retinol article.
Vitamin C, two different problems
L-ascorbic acid
The low pH problem above applies in full, and L-ascorbic acid is also unstable, oxidizing on exposure to air and light.
An oxidized vitamin C serum is both less effective and more irritating, and it is a poor conductor besides.
Keep it in the morning as its own step, after any session rather than during one.
The gentler derivatives
Sodium ascorbyl phosphate, magnesium ascorbyl phosphate and tetrahexyldecyl ascorbate are formulated at higher pH and are considerably gentler.
Those are less likely to sting under current, and that does not make them appropriate conductive media, because most are in emollient or silicone bases that conduct poorly.
Using one as a gel usually produces a weak session that tempts you to raise the level, which is the sequence behind most unpleasant sessions.
A schedule that keeps everything
Morning, cleanse, then your session with a plain conductive gel, then vitamin C, then moisturizer and sunscreen.
Evening on non-acid nights, cleanse, then retinoid if you use one, then moisturizer.
Evening on acid nights, cleanse, then your acid, then moisturizer, and no device that day.
That gives you four or five device sessions a week, daily vitamin C and two or three acid nights, with nothing competing.
If you prefer evening sessions, run the device on the nights you are not using acids and keep the vitamin C in the morning regardless.
What to use as a conductive layer
A plain water-based conductive gel, with no acids, no alcohol, no fragrance and no essential oils.
Hyaluronic acid serums are usually fine despite the name, because hyaluronic acid is not an exfoliating acid and most formulations sit near neutral pH.
Aloe-based gels conduct reasonably well and suit sensitive skin, though they dry faster than purpose-made gels.
Anything oil-based, silicone-heavy or balm-textured will not conduct at all, and how to test your own is in our article on conductive serums.
The comparison between gel, serum and aloe is in our conductor comparison.
The barrier spiral and how to spot it
Acids and vitamin C both increase turnover and, used enthusiastically, thin the outer layer while skin adjusts.
A thinner outer layer has lower electrical resistance, so the same dial setting delivers a stronger sensation than it did last week.
People respond by assuming their skin has become sensitive and reduce moisturizer or add more actives, which makes the next session worse again.
The signs to watch for are redness that persists into the next morning, tightness, flaking around the nose and mouth, and products that never stung starting to sting.
The fix is to stop the actives for a week, keep moisturizing, and restart the device at a lower level once the barrier settles.
If you want the delivery benefit
The Infuse pass on our devices is built for delivery, and the sensible things to pair with it are hydrating and soothing ingredients rather than exfoliating ones.
Hyaluronic acid, panthenol, niacinamide at moderate strength and peptides are reasonable candidates that do not rely on low pH.
We cite the delivery science honestly and we have never measured ingredient penetration on a PureLift device, which is a gap we state rather than paper over, covered in our galvanic article.
Driving an exfoliant deeper is the one use of that pass we would actively tell you to avoid.
Frequently asked questions
Can you use vitamin C before microcurrent
Not as the conductive layer. L-ascorbic acid is formulated at low pH and stings under current. Use a plain conductive gel for the session and apply vitamin C afterward.
Can you use glycolic acid and microcurrent on the same day
Better not to. Acids thin the outer layer while skin adjusts, which lowers resistance and makes the session sting. Alternate days instead.
Does microcurrent make skincare absorb better
Iontophoresis and electroporation have published mechanisms for increasing delivery of charged or small molecules. Whether a given product reaches living tissue depends on its charge, size and formulation, and no brand in this category has measured it on its own device.
What should you not use with microcurrent
Oil-based and silicone-heavy products, which do not conduct, plus alcohol, fragrance, essential oils, exfoliating acids and low pH vitamin C, which irritate under current.
Can you use hyaluronic acid with microcurrent
Yes. Despite the name it is not an exfoliating acid, most formulations sit near neutral pH, and water-based hyaluronic serums conduct well.
