What treatment is contraindicated for clients with pacemakers?

Clients with pacemakers are at a higher risk of complications when exposed to electrical treatments. These treatments, which often involve the use of devices that deliver electrical currents to the skin or underlying tissues for therapeutic or cosmetic purposes, can interfere with the functioning of a pacemaker. The electrical signals from these devices may disrupt the pacemaker's ability to regulate the heartbeat, posing a serious risk to clients' health.

In contrast, facials, waxing, and exfoliation do not involve electrical currents and are generally considered safe for clients with pacemakers. These treatments focus on skin care through mechanical means, such as cleansing, applying products, or physically removing dead skin cells, which do not pose the same risks as electrical treatments. Therefore, it is crucial to avoid any form of electrical stimulation for these clients to ensure their safety.
