# Long-Lived Skin Models Outer Bio Keeps Human Skin Viable for Over Four Weeks By Mursal Rahman | Written with AI assistance | Published 2026-09-16 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/yuna-platform References: [cosmeticsandtoiletries](https://www.cosmeticsandtoiletries.com/testing/tech-equipment-services/news/22972915/outer-bio-launches-yuna-platform-for-ex-vivo-skin-samples) & [businesswire](https://www.businesswire.com/news/home/20260820678439/en/Outer-Bio-Emerges-from-Stealth-with-Yuna-a-Platform-That-Keeps-Ex-Vivo-Human-Skin-Alive-and-Measurable-for-Four-Weeks)  Long-lived skin models are extending how researchers study the effects of skincare compounds on living human tissue. Outer Bio’s Yuna platform keeps full-thickness human skin viable for four or more weeks while preserving its native architecture and resident immune function. This longer testing window allows researchers to examine biological processes such as collagen remodeling, inflammation and [cellular senescence](https://www.trendhunter.com/trends/skin-longevity) that develop over time. Yuna also generates multi-omic data that Outer Bio uses to train [machine-learning models](https://www.trendhunter.com/trends/smartskn) and prioritize compounds for further testing. The platform could give skincare brands, ingredient suppliers and biopharma companies access to more detailed human-skin data before moving potential compounds into clinical studies. Outer Bio can also build a growing proprietary dataset as additional treatments and donors are studied, strengthening its discovery capabilities. By offering Yuna through select partnerships, the company creates another commercial pathway while accelerating the search for new [skincare bioactives](https://www.trendhunter.com/trends/naolys).
