Which facial treatment involves the application of steam?

The application of steam is primarily associated with facial cleansing. This process is designed to open up the pores and soften the skin, which facilitates the removal of impurities, dead skin cells, and excess oil. Steam enhances the effectiveness of facial cleansers and prepares the skin for subsequent treatments by hydrating and rejuvenating it.

In the context of facial treatments, while exfoliation, mask application, and moisturizing are important components, they typically do not involve steam. Exfoliation is focused on removing dead skin, mask application is about delivering targeted ingredients to the skin, and moisturizing aims to hydrate the skin. Steam, however, is specifically utilized during the facial cleansing phase to maximize the efficacy of cleansing by promoting better circulation and allowing for deeper penetration of products.
