If you want to tech up your moisturizer, you can try the JeNu Plus Ultrasonic Infuser ($195). Every second, 365,000 pulses of ultrasound energy vibrate the “microsphere conducting gel” you put on your skin, which helps with the absorption of your ordinary moisturizer by encouraging it to penetrate deeper. The company promises it’s painless, and an older version gets a 95-percent recommendation rate from community members at cosmetic treatment site RealSelf.

“It’s true that if the right kind of ultrasonic vibrations are used on the right kind of ingredient, penetration may be enhanced,” cosmetic chemist Randy Schueller tells Digital Trends in an email. He’s one of the creators of the website Beauty Brains, where scientists answer beauty-related questions. But he adds that the size, shape, and polarity of the ingredients’ molecules will affect penetration, as will the frequency and power of the ultrasonic waves. 

Another device using pulses for skincare is Foreo, which had its Luna 2 on display. The $199 bristle-less silicone device has one side for cleansing and another for anti-aging. The cleaning mode uses 8,000 transdermal sonic pulsations a minute, while lower-frequency pulses supposedly help your skin by making it appear smoother and firmer. It’s the “appear” part that’s crucial, as Foreo isn’t claiming lines and wrinkles will actually disappear.

“Simply applying vibrations to the surface of the skin won’t restore those supportive elements,” says Schueller, referring to collagen and elastin, but “Luna’s massaging effect might plump up the skin and temporarily improve the appearance of fine lines and wrinkles.”
