XCellR8 is a UK-based, pioneering in vitro testing lab for the cosmetics industry, and the only 100% cruelty-free testing lab in the world. Our unique animal-product-free approach maximises the human relevance of the tests and makes us the preferred lab for cruelty-free and vegan brands and their suppliers.

We test ingredients and formulations for safety (including irritation, sensitisation, genotoxicity and acute toxicity) and claim support (including antioxidant, collagen-boosting, skin brightening, anti-inflammatory, a variety of healthy ageing endpoints and our flagship test, XtraMild). We use human cell-based testing and reconstructed human tissue models to generate powerful safety and claim support data.
