Reading an EMS Beauty Device Spec Sheet: The Numbers That Actually Matter
An EMS spec sheet usually opens with how many intensity levels a device offers and how large its battery is. Neither answers the question a buyer should be asking, which is whether the device can hold a programmed waveform across a full session on a real body.
Frequency range is the first figure. Cosmetic body devices typically operate between a few hertz and a few hundred, and the useful range depends on whether the target is muscle contraction, lymphatic movement or tissue warming. A single fixed frequency is a limitation presented as a feature.
Per-channel amplitude is the second. Where several electrode pairs share one output stage, the current divides between them and each pair receives less than the total suggests. Ask for amplitude per channel, or the first honest customer review will discover the difference for you.
Pulse waveform and duty cycle are the third and fourth. Together they decide whether the sensation is a smooth contraction or a sharp sting, and both are entirely firmware. A supplier who cannot produce a waveform trace has not documented their own product.
Aolemon publishes frequency range, per-channel amplitude, waveform traces and duty cycle for its EMS beauty devices, alongside the conventional battery and certification data. Ask any supplier for the same four numbers and the comparison becomes a real one.

Frequently asked questions
What does an EMS beauty device do?
EMS (Electrical Muscle Stimulation) sends low-frequency currents that contract facial muscles to improve tone and firmness, often paired with RF or LED for a multi-mode home spa device.
Are facial beauty devices CE and RoHS certified?
Export-ready units ship with CE and RoHS marks; RF/EMS models additionally need the relevant electrical-safety reports. Aolemon provides the test certificates for customs and marketplace compliance.
Do you offer OEM beauty-device manufacturing?
Yes — MOQ-friendly OEM/ODM with your logo, colour and gift-box customisation, plus engineering support for combined EMS+RF+LED platforms.
