**The answer is a galvanic machine. It uses electrical current to introduce water-soluble products into the skin during a facial.**

A high-frequency machine works differently — it's generally used for its stimulating and germicidal effects on the surface of the skin, not for driving product deeper in. A steamer opens pores and softens skin but doesn't run current at all, which is why galvanic is the specific machine tied to product penetration.
