TikTok's Fave Peter Thomas Roth Eye Tightener Is Back in Stock (for Now)

A decade ago, the skincare brand Peter Thomas Roth released an eye product called the Instant Firmx Eye Temporary Eye Tightener. Described as a "quick fix eye treatment,” it basically promises to do it all—depuff, minimize crow’s-feet and wrinkles, and firm the under-eye area—if only temporarily.

Fast-forward to this summer, and Trinidad Sandoval, aka TikTok user @trinidad1967, turned the $38 product into a sensation. In the video, which now has over 30 million views, she explains how weight loss surgery gave her exaggerated eye bags and says this is the one product that helps. She applies a bit of the eye tightener underneath one eye, and poof, the results are visible—and near-instantaneous. Cue a skincare TikTok obsession, with fans including @tinx showing off their results. Naturally, the 10-year-old product has been all but impossible to get your hands on since.

But good news: If you act fast, you can catch it right this second. And if by the time you read this it’s too late, don’t worry: I’m sharing some other amazing products that will help nix puffiness and under-eye circles in no time.
