Which technology is also incorporated in some ultrasonic devices?

Ultrasonic devices utilize high-frequency sound waves to penetrate the skin and promote various skin benefits, such as deep cleansing, increased circulation, and enhanced absorption of products. Microcurrent technology, which involves the use of low-level electrical currents, is sometimes integrated with ultrasonic devices to amplify their efficacy. This combination can aid in muscle toning, improve skin elasticity, and enhance cellular activity, providing a more comprehensive treatment that addresses various skin concerns simultaneously.

In contrast, while LED, high frequency, and IPL technologies have their own distinctive applications and benefits in esthetics, they are not typically incorporated within ultrasonic devices. LED therapy uses light at specific wavelengths to treat conditions like acne and promote healing, high frequency employs electrical currents for antiseptic properties and stimulating hair growth, and IPL involves a wide spectrum of light for hair removal and skin rejuvenation. Each of these technologies operates based on different principles and methods than ultrasonic and microcurrent technologies, hence why microcurrent is the appropriate choice for this question.
