Wisconsin Esthetics State Board Practice Test 2026 – Comprehensive Exam Prep

The primary purpose of galvanic current in esthetics is indeed to force water-soluble skincare products into the skin. This is achieved through a process known as iontophoresis, where electrical current is utilized to enhance the penetration of active ingredients from skincare products into the epidermis. The galvanic current creates a positive or negative charge that allows the charged particles in the skincare products to move into the skin more effectively than through passive absorption. This method is especially beneficial for treatments that aim to hydrate, nourish, or treat specific skin conditions, as it enhances the efficacy of the applied products.

In contrast, the mechanical effect associated with other modalities does not focus on the transdermal delivery of solutions. Stimulation of muscle contractions is more aligned with modalities such as faradic current, while providing heat is typically achieved through techniques like infrared therapy or other heat-based applications, which do not capitalize on the chemical penetration aspects facilitated by galvanic current.
