Biohacker Bryan Johnson, known for his unconventional and often expensive anti-aging routines, has drawn attention for a new skincare practice that costs less than $20. The hack involves using a reusable silicone face mask from the brand Experiment, which is currently priced at $19 on Amazon.

The mask gained traction after Johnson posted a video of himself wearing the bright green mask outside his sauna. Experiment CEO Lisa Guerrera responded to the video on TikTok, noting that while Johnson's application might be unusual, the product is designed for skincare.

"He is using it to protect his skin in the sauna," Guerrera explained. "You could totally do that." She added that the mask can be used with any preferred serums.

The Avant Guard mask features a patent-pending design with "squiggly ear loops" intended for a comfortable fit. Reviews on Amazon have also highlighted its comfortable fit, with one user noting it "fits a man’s face almost perfectly."

Unlike disposable sheet masks, the silicone mask is reusable, aiming to reduce waste. Experiment also offers its own "super saturated" hydrating serum, formulated with glycerin and polyglutamic acid, available for $28 on Amazon.

Amazon's Prime Day event, scheduled for October 6-7, may feature additional deals on the product, though many sales are already active. The mask is available on Amazon in standard and large sizes.
