Lady Gaga publicized details about Outer Bio, a skin health research company she co-founded with her fiance Michael Polansky, in a tweet Friday night, August 21, 2026.
According to its website, Outer Bio pairs "machine learning with full-thickness human skin that stays alive for weeks." Its goal is to discover and validate skin mechanisms and bioactives through human tissue testing. Chronic inflammation, aging-associated tissue remodeling and environmental stress are some of the skin tissue dysfunctions Outer Bio models.
The company is unique with its innovative discovery platform YUNA, which unites living human skin tissue, automated in vitro screening and biomedical AI to discover new molecules and mechanisms to advance skin health.
Gaga sits on the platform's Board of Directors alongside Polansky, who is also the chief executive officer, and Sara Choi.
Gaga's involvement with the research firm was first revealed in her November 2025 Rolling Stone cover story, in which Polansky said, "It was her idea. She's officially on the board of directors, but they've kepy her name out of it until now. The attention that Stefani's involvement would bring wasn't necessary – it's not consumer-facing. ... When she talks about us being partners, it kind of looks like it all goes one direction, but she's the most incredible support to me as well."
