Amazon Prime Day is drawing to a close, and one of the standout gadget deals is the Shark CryoGlow LED face mask, now priced at $299. That is $50 off its regular $350 price, and WIRED notes it is the lowest price the device has reached so far.

The mask is notable for combining blue, red, and infrared light with built-in cooling under-eye pads. It offers two treatment modes—Blemish Repair and Better Aging—and automatically switches wavelengths and session lengths. After eight weeks of consistent use, the manufacturer recommends a four-minute Skin Sustain mode to maintain results.

WIRED contributor Verity Burns tested the mask over eight weeks and reported that her perioral dermatitis cleared faster than usual, with plumper, brighter skin. An aesthetician's scan also showed reduced inflammation and hyperpigmentation, plus improvement in fine lines. The deal is only available for a limited time, and Prime Day prices can change without warning.
