Experiment Beauty Avant Guard is the lime-green silicone mask that spiked after Bryan Johnson's alien look
Skip the disposable sheet. This reusable silicone mask seals in your serum, rinses clean, and looks exactly as sci-fi as the internet promised.
Experiment Beauty Avant Guard is the bright lime silicone sheet mask that took over shopping feeds after biohacker Bryan Johnson was spotted with it. Unlike a single-use paper mask, this one is reusable medical-feel silicone you layer over hydrating serums or moisturizers, then rinse and hang to dry.
USA Times shopping coverage on September 16, 2026 walked through the spike: Experiment CEO Lisa Guerrera recognized the patented squiggly ear loops in Johnson's clip and joked that he was using the mask as sauna skin protection as much as a serum booster. The Amazon listing we are watching is the large size around nineteen dollars.
The honest caveat is what you put underneath. Experiment tells shoppers not to seal prescription tretinoin, strong retinols, or exfoliating acids under the mask, because occlusion can intensify irritation. Stick to hydrating products, start with a short wear, and use the brand's fit quiz if you are between small and large.

Why we like it
It is a skincare find with a memorable look and a practical reuse loop. We like that the brand is clear about occlusion limits, and that the Bryan Johnson moment made a niche silicone mask suddenly easy to explain in one photo.
