Which modality is most commonly used in electrotherapy?

Galvanic current is frequently used in electrotherapy primarily due to its ability to produce chemical effects through ionization. This modality functions effectively in various skin treatments, such as those aimed at enhancing product penetration, reducing the appearance of fine lines, and improving overall skin hydration.

Galvanic current employs a direct electric current to facilitate the movement of ions in the skin, allowing for deep cleansing and the infusion of active ingredients. Its use in cosmetic procedures can be particularly beneficial for delivering treatments like desincrustation, where impurities are drawn out of the skin, and iontophoresis, which helps in the absorption of therapeutic products.

The other modalities have their own specific applications and benefits. Sinusoidal current, for instance, is often used for muscle stimulation and is less common for general skin treatment. Microcurrent is recognized for its lifting effects and is often used during facial treatments, but it does not have the same broad range of chemical effects as Galvanic current. High-frequency current is effective in treating acne and promoting circulation but is more focused on specific treatments rather than the extensive applications provided by Galvanic current. Thus, Galvanic current stands out as the most commonly employed modality in electrotherapy within esthetics.
