According to its user guide, SKINFOUNDRY Halo is for adults only and should not be used if you are pregnant, if you have heart disease, blood disease or cancer, or on wounded skin. Because it includes EMS muscle stimulation, anyone with a pacemaker or other implanted electronic device should not use it without clearance from the doctor who manages that device. Used as directed, each mode runs five minutes, starts at Level 1, and the RF warmth is capped at 40 degrees C.

Who should not use SKINFOUNDRY Halo
These cautions are printed in the SKINFOUNDRY Halo user guide, word for word:
- “For adult use only, keep away from children.”
- “Do not use if you are pregnant.”
- “Do not use if you have heart disease, blood disease, cancer, etc.”
- “Do not use on wounded skin.”
- “Do not have treatment on same area for too long.”
- “Stop using if you feel uncomfortable and consult your dermatologist.”
- “Do not disassemble.”
The list ends with “etc.,” so if you have a serious or ongoing health condition that is not named, ask your doctor before starting.
Pacemakers and implanted electronic devices
The guide names heart disease but not pacemakers specifically. SKINFOUNDRY Halo includes EMS (electrical muscle stimulation), and US FDA rules for powered muscle stimulators require the warning that they “should not be used on patients with cardiac demand pacemakers” (FDA guidance). International standards for stimulation devices say the same for any implanted electronic device unless a specialist has approved it. If you have a pacemaker, an implanted defibrillator, a cochlear implant or a neurostimulator, do not use SKINFOUNDRY Halo without clearance from the physician who manages that device.
Metal implants, plates and dental work
The guide does not address metal implants. As general guidance, ask the surgeon or dentist who placed facial plates, screws or implants before using any RF or EMS device over that area, and do not treat directly over hardware you can feel under the skin.
Pregnancy and breastfeeding
The guide is clear: do not use SKINFOUNDRY Halo if you are pregnant. It does not mention breastfeeding. Ask your doctor or midwife before using it while breastfeeding.
Skin you should not treat
- Wounded or broken skin. Cuts, open blemishes, grazes, fresh injection points, and skin that is still healing after a procedure.
- Eyelids. In Eye Care mode, the guide says to work “around the orbital bone (not on eyelid)” and to “never use directly on eyelids,” at Level 1 with very light pressure.
- Dry skin. The guide says to “never use on dry skin.” Apply Lumis, the treatment gel made for SKINFOUNDRY Halo, to both the skin and the probe in every mode except Clean, which uses cleanser on damp skin.
For skin conditions such as rosacea, and for retinol users, see using a facial device with retinol, rosacea or sensitive skin. After Botox or fillers, see RF or microcurrent after Botox or fillers.
