Question: 1 / 580

What is the main use of galavanic machines in skincare?

Exfoliating

Deep cleaning

Introducing products

Galvanic machines are primarily used for introducing products into the skin. This technique, known as iontophoresis, utilizes a direct current to enhance the absorption of active ingredients from skincare products, allowing them to penetrate deeper into the dermis. This is particularly beneficial for serums and moisturizers, as it increases their efficacy and provides targeted treatment to specific skin concerns.

The use of galvanic machines can significantly improve the delivery of beneficial substances into the skin, making it a popular choice for advanced skincare treatments in salons and spas. While exfoliation, deep cleaning, and massaging are important aspects of skincare, galvanic machines specifically focus on enhancing the absorption of products, thereby maximizing their effectiveness. This distinct purpose is what sets them apart in the realm of skincare treatments.
