Which machine is used to supply galvanic current for beauty treatments?

The iontophoresis machine is specifically designed to supply galvanic current for beauty treatments. This type of machine utilizes low-level direct current to enhance the penetration of active ingredients into the skin, making it effective for various applications such as hydration and anti-aging treatments. The process involves using electrodes to create an electrical field, allowing charged ions in the product to move into the skin more effectively.

In contrast, high-frequency machines produce an alternating current that primarily helps with acne treatment and creating thermal effects in the skin. Ultrasound machines use sound waves to facilitate deeper product penetration and skin rejuvenation but do not supply galvanic current. Microcurrent machines utilize very low-level electrical currents to stimulate facial muscles and improve skin tone but are not focused on delivering galvanic current. Understanding these distinctions clarifies why the iontophoresis machine is the correct answer in the context of galvanic current usage.
