Longevity Health Holdings is a small cosmetic skincare and haircare company focused on the anti-aging segment of the beauty market. The company sells two product lines built around biological ingredients — growth factors, exosomes, and proteins derived from human cells or platelets — that it markets as scientifically advanced alternatives to conventional skincare. The primary line, Elevai Exosomes, uses nano-sized extracellular vesicles derived from human umbilical mesenchymal stem cells, with products targeting post-aesthetic treatment skin support, daily skincare, and hair growth. A second line, Carmell Secretome, uses growth factors and proteins extracted from human platelets, but the company de-emphasized this line in 2025 to focus on Elevai. Longevity sells primarily through the professional medical aesthetics channel — dermatologists, plastic surgeons, and medical spas — who use or recommend products alongside in-office procedures like microneedling and laser treatments. The company also sells direct-to-consumer through its own websites and through third-party distributors. Longevity manufactures its products in its own U.S.-based, FDA-inspected, cGMP-compliant facilities, purchasing raw biological materials from third parties and processing them in-house. This model gives the company quality control but also means it bears fixed manufacturing costs at limited scale. The company has only 10 full-time employees and is focused on expanding its physician account base and distributor network to grow the Elevai line.
