The beauty device market has exploded, thanks to a growing demand for products that amplify the results of skincare formulations. Whether you’re looking to define cheekbones, reduce visible wrinkles or tackle a frustrating skin problem, there’s now a product for just about everything. The key is to select a device that addresses a specific need such as skin tightening device.

For example, if you have trouble with acne scarring, this device helps plump the area by stimulating collagen production and promoting cell turnover. This is accomplished with sonic vibrations, thermal energy and LED light therapy. “The combination of these techniques works to stimulate the cells, improve circulation and increase hydration,” says dermatologist Dr. Lisa Song.

Another way to improve acne scarring is with fillers, which help smooth the divots left behind by blemishes. While they’re not a permanent solution, “they give an immediate effect and can be used in conjunction with a topical regimen,” Song says.

For those with sensitive skin, a low-frequency thermal massage can be used to stimulate the skin’s natural healing response. This is accomplished by sending gentle pulses of heat to the deep layers of the skin, which helps break down inflammatory proteins that cause redness and irritation. “It’s an ideal treatment to use on any areas with a lot of scarring, especially in the undereye area,” Song says.

You’ll often see high-frequency facials at spas, but the same technology is now available at home. This wand uses a small electrode to send oxygen into the skin, which kills acne-causing bacteria on contact and zaps pimples before they get big.

When using a high-frequency facial, start with a clean face and apply a serum. Benjamin recommends one with epidermal growth factors, like Stacked Skincare’s EGF Activating Serum or Nurse Jamie’s EGF Platinum 3 Restorative Facial Elixir, because the growth factor boost helps speed up skin’s repair process. Then, place the wand over your face and work on each spot for just three to five minutes.

If you have stubborn spots, this skin tightening machine wand uses a combination of sonic waves and high frequency to zap them, says Song. The wand also uses microcurrents to help firm the skin and boost collagen production, which can soften fine lines and wrinkles.

The device has a light mode for each skin issue (red for wrinkles, blue for acne, yellow for discoloration and pink for hydration). Its strobing function also opens pores to improve product absorption for better hydration.
