Which treatment focuses primarily on enhancing the penetration of skincare products?

Iontophoresis is recognized for its specific function in enhancing the penetration of skincare products into the skin. This technique utilizes a mild electrical current to drive active ingredients from topical products deeper into the epidermis and dermis. By improving the permeability of the skin, iontophoresis allows for more effective absorption of active ingredients, which can lead to improved results from the treatments being applied.

In contrast, microdermabrasion primarily focuses on exfoliating the outermost layer of skin. This process removes dead skin cells, promoting skin renewal but does not specifically enhance penetration of skincare products in the same active way as iontophoresis. A chemical peel, while also promoting exfoliation and skin renewal, functions through the application of chemical solutions rather than electrical currents to improve skin appearance and texture but is not designed for the penetration of products in the same manner. The Hydrafacial treatment offers hydrating and cleansing benefits through various techniques, including exfoliation and infusion of serums, but again does not employ the penetrating electrical method that iontophoresis does.

Thus, iontophoresis stands out as the treatment primarily aimed at leveraging electric currents to facilitate the deep absorption of skincare solutions.
