Which type of electrotherapy is recommended for a client with very oily, impacted skin when using a desincrustant product?

1. Positive galvanic current

2. High-frequency current

3. Negative galvanic current

4. Microcurrent therapy

The correct answer is: Negative galvanic current

The use of negative galvanic current is particularly effective for clients with very oily and impacted skin, primarily due to its ability to aid in deep cleaning and clearing congested pores. When a desincrustant product is applied to the skin, a negative galvanic current helps to facilitate the penetration of the product, which softens and emulsifies sebum and other impurities within the pores. This method works by using a negatively charged electrode, which repels the negatively charged particles in the desincrustant solution, increasing their penetration into the skin. As a result, this can lead to the breakdown of oils and debris, making it easier for them to be removed. The treatment helps in addressing issues associated with oily skin, such as acne and blockages, fostering a clearer complexion and better skin health. In comparison, other forms of electrotherapy have different primary functions. Positive galvanic current can promote tissue repair and hydration but is not ideal for deep cleansing oily skin. High-frequency current is helpful for increasing circulation and targeting bacteria, but it is typically used after initial cleansing, rather than for desincrustation. Microcurrent therapy primarily stimulates facial muscles and enhances product absorption, which does not directly address the concerns of oily, impacted skin in
