Pacemaker, Tretinoin, and the Galvanic Machine

No. The implanted pacemaker is an absolute bar to galvanic current for this client, and her good experience a year ago is irrelevant.

Reasoning:

• Galvanic current passes a direct current through the body between an active electrode and a return electrode, with the client as part of the circuit. A pacemaker is an implanted electronic device with leads sitting in the heart; imposed current, however small in cosmetic terms, creates a risk of device interference or arrhythmia.
• The timeline in her history is the trap. If the prior galvanic treatment was 'about a year ago' and the pacemaker was implanted three years ago, her memory of the sequence may be wrong - she may be recalling a treatment from before the implant, or a different modality. Client recall of device dates and treatment names is unreliable; the intake answer, not the anecdote, governs.
• Any electrical modality that could route current through the torso is off the table: galvanic, microcurrent, and any body-current device. I do not 'just use the low setting.' There is no safe cosmetic dose to negotiate.
• High frequency (Tesla) is a different animal - it is a high-frequency, high-voltage, low-amperage alternating current applied locally with a glass electrode. It is widely used with cardiac devices only under the same caution, and given she has an implant, my judgment is to skip it too rather than split hairs. The steamer and manual work carry no electrical risk.
• Documentation: I record the device, the date if she knows it, and the fact that I declined electrical treatment and why, and I ask her to confirm with her cardiologist before any future electrical service. A note protects her and me.

What I actually say: 'The machine you loved isn't safe with a pacemaker - the current travels through your body, and I'm not going to run current near a heart device. I can give you a treatment that gets you the same hydration without it.'

Session design, electrical-free:

1. Intake and consent, with the pacemaker, tretinoin, cold-sore history, and dental implants all documented. I ask what her skin does after a facial and what her last two weeks of product use looked like - the tretinoin is two months old, which means her barrier may still be adjusting.
2. Double cleanse, fragrance-free, tepid. No exfoliating cleanser, no washcloth scrub, given retinoid use.
3. Steamer - yes, but brief and at distance. Steam softens the stratum corneum and feels like the 'spa' experience she came for; I keep it short and keep it off her nose and mouth if she reports any tingle, because of the cold-sore history. Heat is a known trigger for herpes labialis reactivation.
4. Massage - yes. Manual lymphatic and petrissage work delivers the relaxation and circulation benefit she associates with the machine, with no electrical risk.
5. Mask - calming/hydrating, not the enzyme or the 15% glycolic. On nightly tretinoin her barrier is already turning over faster than normal; adding an enzyme or a 15% acid is stacking exfoliation and risks a retinoid-plus-acid reaction two months in. The glycolic serum stays in the cabinet.
6. Finish with barrier moisturizer and broad-spectrum SPF 30+. On tretinoin she is photosensitive; this is not optional.
7. Rebooking note in the file: 'no electrical modalities - pacemaker; cardio clearance required before reconsidering.'

If she pushes for 'the machine,' I offer high-frequency spot treatment only if I have decided it is acceptable in her case - and my default here is no. The honest framing is that the hydration she wants comes from humectants and occlusion, not from current.

In the room, tretinoin means 'no added exfoliation and no trauma':

• No scrub, no enzyme, no glycolic, no extraction-heavy work. Her epidermis is turning over faster and is thinner and more permeable than baseline; the goal is to avoid the second insult.
• No waxing of the lip or brows - retinoids are a well-established reason to defer waxing because of skin lifting and tearing. She did not ask for waxing today, but I raise it, because a client on tretinoin who books a lip wax next month is a predictable injury.
• Careful with friction and heat: gentle pressure, brief steam, no vigorous massage on thin skin.

At home:

• Keep the tretinoin at night, pea-sized, on dry skin, but I do not change her prescription schedule - that is between her and her prescriber. What I do is ask how her skin is tolerating it and tell her that if she is peeling or stinging, the conversation to have is with the prescriber, not with a new acid I sell her.
• SPF 30+ every morning, reapplied. Retinoids increase photosensitivity; this is the highest-yield thing I can say to her.
• Barrier moisturizer, applied on damp skin, morning and night.
• A simple, fragrance-free routine. No new actives layered on top of a retinoid because a friend recommended them.
• Cold-sore watch: if she feels the tingle, reschedule - do not come in and ask me to work around it.

I write the deferral reasons on her record card so the next person in my chair does not have to rediscover them, and so the waxing contraindication is impossible to miss.
