In facial treatments aimed at skin rejuvenation, diathermy is particularly effective due to its ability to use high-frequency electrical currents to generate heat within the deeper layers of the skin. This heating process helps to increase blood flow and stimulate cellular metabolism, ultimately promoting collagen remodeling and skin tightness. This therapeutic approach can lead to improved skin texture and elasticity, making it a popular choice in esthetic practices for rejuvenating the skin.

Direct current, while used in some skin treatments, typically focuses on iontophoresis or galvanic treatments, which are more specific to product penetration rather than overall skin rejuvenation. Alternating current is more commonly associated with various electrical treatments but does not specifically target rejuvenation as effectively as diathermy. Therapeutic ultrasound, while beneficial for certain skin conditions, does not fall under the same category as diathermy for rejuvenation purposes and focuses more on deeper tissue healing rather than surface-level rejuvenation.

Thus, diathermy stands out as the best choice for skin rejuvenation in facial treatments due to its unique properties and benefits.
