Microcurrent safety: who should not use these devices

This list is short enough to read in full, and the first item on it is absolute. These are the manufacturers' own contraindications, not our interpretation of them.

The list

The manufacturer contraindications

Condition	Status	Why
Implanted electrical device (pacemaker, ICD, DBS, cochlear implant)	Absolute - do not use	Risk of interference with implanted electronics
Pregnancy	Do not use	Not studied; manufacturers exclude it rather than assert safety
Epilepsy or a seizure disorder	Do not use without medical advice	Electrical stimulation is excluded as a precaution
Active malignancy in the treatment area	Do not use	Standard exclusion across electrical and energy-based devices
Metal implants or plates in the treatment area	Ask first	Current behavior around implanted metal is device-specific
Recent injectables or dermal fillers	Wait; ask the injector	Timing advice varies; the injector knows your specific case
Active infection, open wounds or inflamed acne in the area	Avoid that area	Avoid current and mechanical contact over compromised skin
Recent facial surgery	Ask your surgeon	Depends entirely on the procedure and how recent
Children	Not intended	Not tested in this population by any manufacturer

Compiled from manufacturer contraindication lists across the devices covered on this site, checked 13 October 2026. Always read the list supplied with your specific device - it is the authoritative one.

A common question

Why pregnancy is on the list

Not because there is evidence of harm, but because there is no evidence either way. Manufacturers exclude pregnancy from the indications for most electrical and energy-based devices as a default, because testing in that population does not happen.

That is an honest position rather than an alarming one, and the correct response is to follow it rather than to reason your way around it.

Do not panic about these

Things that are normal, not warnings

A metallic taste. Current interacting with dental fillings or crowns. Normal, harmless, and almost everyone searches for it after the first session.
A faint tingle. Expected. Microcurrent should be barely perceptible.
Brief redness after a session. Usually from the mechanical contact and the gel, not the current.
No sensation at all. Also normal, and not a sign the device is off. Microcurrent runs below the sensory threshold for many people.

Stop and reassess

Things that are not normal

Visible muscle twitching. The current is above the contraction threshold. Turn it down, or recognize that the device is operating as EMS. The difference.
A sharp or stinging sensation. Almost always a gel problem - insufficient conductive medium concentrating current at a contact point. Gel guide.
Persistent redness or irritation hours after a session.
Aching in the treated muscles afterwards, which suggests over-stimulation rather than microcurrent.
A headache during or after sessions, particularly with periorbital work.

None of these is an emergency. All of them are reasons to stop the session rather than finish it, and to reduce intensity or frequency before trying again.

Placement

Areas to avoid

Directly on the eyelid, unless the device's own instructions specifically direct it with an eye-specific attachment or routine.
The front of the throat over the thyroid and carotid area. Manufacturer neck patterns route around it; follow them rather than improvising. Neck technique.
Over active inflamed acne or broken skin.
Over an area with recent injectables, until whoever administered them says otherwise.

Getting advice

When to ask rather than read

This page reports what manufacturers publish. It is not medical advice and we are not clinicians. If you have a condition on the list above, or one you are not sure about, the conversation is with a clinician and it will take five minutes.

We would rather you did that than buy a device on the strength of a web page, including this one.

FAQ

Questions people actually ask

Can you use microcurrent with a pacemaker?

No. An implanted electrical device - pacemaker, implanted defibrillator, deep brain stimulator, cochlear implant - is an absolute contraindication on every manufacturer's list, because external current can interfere with implanted electronics.

Is microcurrent safe during pregnancy?

Manufacturers exclude pregnancy from the indications for these devices. That reflects an absence of testing rather than evidence of harm, and the correct response is to follow the exclusion.

Is a metallic taste during microcurrent normal?

Yes. It is current interacting with dental fillings or crowns, and it is harmless. Almost everyone who experiences it searches for it afterwards.

Can you use microcurrent after fillers or Botox?

Wait, and ask whoever administered them. Timing guidance varies by product and by injector, and they know your specific case in a way a general web page cannot.

What should you do if microcurrent stings?

Stop and add more conductive gel. A sharp or stinging sensation almost always means insufficient conductive medium is concentrating current at a contact point, rather than a device fault.
