What machine introduces water-soluble products into the skin during a facial?

1. Vaporizer

2. Galvanic machine

3. Desincrustation machine

4. Facial steamer

The correct answer is: Galvanic machine

The galvanic machine is designed to introduce water-soluble products into the skin through a process known as iontophoresis. This technique utilizes a low-level electrical current to drive ionized products through the skin, enhancing product penetration and effectiveness. When the appropriate positive or negative charge is applied via the machine, it causes the active ingredients in treatments to be absorbed more deeply into the skin, which can improve the overall results of facial treatments. This process is particularly useful for products that require deeper penetration, like serums or other hydrating agents. The ability of the galvanic machine to facilitate this kind of absorption makes it a key tool in facial treatments, especially for clients looking to address specific skin concerns. In contrast, while a vaporizer, desincrustation machine, and facial steamer are all beneficial tools used in facial treatments, they serve different primary functions. The vaporizer and facial steamer primarily create a moist steam to help open up the pores and prepare the skin for deeper cleansing and exfoliation, while the desincrustation machine is typically used in conjunction with a specific gel to soften and break down sebum and debris in the pores, rather than directly introducing products into the skin.
