Which treatment technique is classified as Class 2 and is out of scope for estheticians in the US?

The treatment technique that is classified as Class 2 and is out of scope for estheticians in the US is Faradic devices. These devices utilize electrical currents to stimulate muscle contractions, and due to their therapeutic and medical applications, they fall under the Class 2 medical device category. As such, they require specific training and are typically regulated more stringently than the Class 1 devices often used by estheticians.

In contrast, Tesla high-frequency devices, microcurrent devices, and galvanic devices are generally considered more appropriate for esthetic use and do not carry the same regulatory restrictions as Class 2 devices. This distinction is crucial for estheticians in understanding the scope of their practice and the types of equipment they are allowed to use in a professional setting.
