What is a tool frequently used in facials to promote skin hydration through steam?

The steamer is frequently used in facials to promote skin hydration through steam because it effectively introduces moisture to the skin. The warm steam opens up the pores, allowing for deeper penetration of products and enhanced cleansing. It also helps to soften the skin, making it more receptive to subsequent treatments like exfoliation or extraction. Additionally, steam can increase blood circulation and oxygen flow to the skin, which can result in a healthier and more radiant appearance. By creating a humid environment, the steamer aids in keeping the skin hydrated, making it an essential tool in facial treatments.
