Ultrasound technology has long been associated with medical diagnostics, but in recent years, its application in the skincare industry has gained significant traction. Estheticians and skincare professionals are increasingly leveraging this technology to offer non-invasive treatments for skin tightening, rejuvenation, and regeneration. This article delves into the fundamentals of ultrasound technology, its mechanism of action, common uses in skincare, and the variations among devices designed for aesthetic purposes.
Understanding Ultrasound 2 Primary Types Of Technology
Ultrasound refers to sound waves with frequencies higher than the upper audible limit of human hearing, typically above 20 kHz. In skincare, these high-frequency sound waves penetrate the skin layers to promote cellular repair and regeneration, making it a versatile tool for various aesthetic treatments.
The two primary types of ultrasound used in skincare and aesthetics are:
Low-Frequency Ultrasound (LFU)
Typically operating between 20 kHz and 100 kHz, LFU is known for its deeper penetration, making it suitable for treatments requiring more profound effects, such as fat reduction or cellulite treatment.
High-Frequency Ultrasound (HFU)
Operating above 1 MHz, HFU is used for more superficial treatments. It is ideal for skin tightening, enhancing product penetration, and stimulating collagen production, leading to firmer, more youthful skin.

She has an extensive and diverse background in healthcare, with over a decade of experience working in emergency, critical care, trauma, aesthetics, healthcare administration, and healthcare education. Krystal holds multiple board certifications, including family practice, emergency, and critical care.
In 2020, Dr. Briglia founded Triada Integrative Medicine and Wellness, a New Jersey based practice. She developed the wellness center with her husband who also practices in healthcare as a psychiatric nurse practitioner. The couple met while working in the emergency department and witnessed firsthand the healthcare gaps patients experience seeking treatments and care to feel better, which inspired them to do more for the community. Their medical backgrounds and collective experiences inspired them to develop a plan to integrate access to multiple treatments in one place to take care of the whole person, helping patients reach their optimal level of wellness as a whole person, instead of addressing segregated, individual issues.
3 Ways Ultrasound Technology Works in Skincare
Ultrasound technology in skincare relies on the mechanical energy generated by sound waves. When ultrasound waves are directed at the skin, they create micro-vibrations within the tissues. These vibrations lead to thermal effects, mechanical effects, and cavitation—each playing a unique role in skincare treatments:
1 Thermal Effects
The heat generated by ultrasound waves increases blood circulation and stimulates the production of collagen and elastin fibers, essential proteins for skin elasticity and firmness.
2 Mechanical Effects
The micro-vibrations help in the breakdown of fat cells and improve lymphatic drainage, making ultrasound effective for contouring and reducing puffiness.
3 Cavitation
This refers to the formation of tiny gas bubbles within the skin tissues. These bubbles collapse, creating shockwaves that further enhance the treatment’s efficacy by promoting cellular turnover and breaking down fat deposits.
5 Common Applications of Ultrasound in Skincare
Ultrasound technology is employed in various aesthetic treatments, each targeting different skin concerns:
1 Skin Tightening
High-frequency ultrasound stimulates collagen production, tightening the skin and reducing the appearance of fine lines and wrinkles. Treatments like Ultherapy® or Sofwave® utilize this principle to lift and firm the skin without surgery.
2 Fat Reduction and Body Contouring
Low-frequency ultrasound is used in treatments like Ultrasonic Cavitation to target stubborn fat areas. The sound waves break down fat cells, which are then naturally eliminated by the body.
3 Cellulite Reduction
The mechanical effects of ultrasound help in smoothing out dimpled skin caused by cellulite, making the skin appear more even and toned.
4 Product Penetration
Ultrasound enhances the penetration of skincare products by temporarily disrupting the skin barrier, allowing active ingredients to reach deeper layers for more effective results.
5 Acne Treatment
Ultrasound can also be used to reduce inflammation and kill bacteria in acne-prone skin, promoting healing and preventing future breakouts.
Technology Behind Ultrasound Devices for Skincare
Different ultrasound devices vary in frequency, intensity, and application, making each suitable for specific treatments. The following are key technologies behind these devices:
Focused Ultrasound (FUS)
This technology concentrates ultrasound energy at a specific depth in the skin, allowing for precise targeting of tissues. Devices like Ultherapy® use FUS to lift and tighten skin by stimulating collagen production in deeper layers without affecting the surface.
HIFU (High-Intensity Focused Ultrasound)
HIFU technology is similar to FUS but delivers higher energy levels. It is used for more intense treatments, such as non-surgical facelifts, where significant skin tightening is required.
Ultrasonic Cavitation Devices
These use low-frequency ultrasound to create cavitation, effectively breaking down fat cells. They are commonly used for body contouring and fat reduction treatments.
Ultrasonic Spatulas and Wands
Often used in facials, these devices emit high-frequency ultrasound waves to exfoliate the skin and enhance the absorption of serums and other skincare products.
Differentiating Ultrasound Devices
The primary differences among ultrasound devices lie in their frequency, intensity, and the area of application. For instance, devices designed for facial treatments typically use high-frequency ultrasound for superficial effects, while those aimed at body contouring utilize low-frequency ultrasound for deeper penetration and fat reduction. The energy output and precision of the device also play a crucial role in determining its effectiveness and suitability for different treatments.
Wrap Up
Ultrasound technology is revolutionizing the skincare industry, offering non-invasive solutions for a variety of aesthetic concerns. By understanding the different types of ultrasound, how they work, and their specific applications, estheticians and other skincare professionals can effectively incorporate this technology into their practice to enhance treatment outcomes and client satisfaction. Be sure to verify your own state rules and regulations regarding scope of practice surrounding use of ultrasound technology.
As this technology continues to evolve, staying informed about the latest advancements and devices will be key for skincare professionals aiming to provide cutting-edge treatments in a competitive market.
