What treatment is known for nourishing deeper layers of the epidermis?

Microdermabrasion
Iontophoresis
Exfoliation
Steam treatment

The correct answer is: Iontophoresis

Iontophoresis is recognized for its ability to nourish the deeper layers of the epidermis through the use of electrical currents that enhance the absorption of nutrients and therapeutic agents. This method employs a device that generates a mild electrical current to facilitate the penetration of products into the skin, allowing active ingredients to reach deeper layers where they can have a more significant impact on cellular function and overall skin health. In comparison, microdermabrasion primarily focuses on the exfoliation of the outer layer of the skin, which improves texture and can enhance surface appearance but does not significantly reach or nourish deeper layers. Exfoliation as a general practice helps remove dead skin cells from the surface but does not involve deep nutrient delivery. Steam treatments, while beneficial for opening pores and hydrating the outer layers of the skin, do not effectively transport nutrients into the deeper epidermal layers as iontophoresis does. Thus, iontophoresis stands out as the treatment specifically designed to nourish the deeper layers of the epidermis.
