Who would have thought that the same technology used to allow pregnant women to view their fetuses in the womb could help make your skin look younger and smoother? Ultrasonic technology has been used in cosmetic procedures for nearly 30 years and this “luxury” skin treatment is creating a buzz in both spa and home skin care.

Ultrasound refers to sound waves with a frequency higher than human hearing (typically above 20,000HZ). When applied to the body, these high-frequency sound waves stimulate cell growth and regeneration and improve circulation, increasing the penetration of other skin care products.

Ultrasound is often used before and after plastic surgery to reduce swelling and puffiness. It has also been shown to be an effective treatment for fine lines and wrinkles, sun damage and age spots. Many spas offer “Ultrasonic Facials” to exfoliate the skin and help fight these visible signs of aging.

An ultrasonic facial uses ultrasound frequency to exfoliate dead skin cells without the irritation or redness sometimes resulting from microdermabrasion. The ultrasound loosens and removes dirt, oil and debris from the skin, reducing bacteria levels and pore size. It also stimulates the skin’s cells, encouraging production of collagen and elastin, helping to firm and tighten. It is completely non-invasive and safe for all skin types, even the most sensitive.

Ultrasonic skin treatments need to be performed regularly to see long-term results. Although you may feel some difference after the first treatment, a series of 6-12 treatments will ensure more lasting results.

Ultrasonic facials can also be combined with other treatments. The inflammation-reducing effects of ultrasonic exfoliation makes it an ideal after treatment for microdermabrasion, glycolic and other peels. It can remove dead cells and leftover crystals better than most other cleansing techniques. The results of ultrasonic facials also enable the hydrating and anti-oxidant ingredients in anti-aging serums and lotions to penetrate more deeply for maximum results.

In a spa or salon environment, ultrasonic facials can range in cost from around $80 to $150. Ultrasonic facial equipment is also available for home use from a variety of manufacturers. These range in price anywhere from $50 on the low end to $400 or more on the high end.

Although ultrasonic facials are safe and effective for all skin types, there are certain conditions that will prohibit their use. If you are pregnant or have a pacemaker, seizures, thyroid problems, metallic implants, silicon implants, infections, open wounds or sores, you should avoid ultrasonic facial treatments.
