A product labeled vegan contains no ingredients sourced from animals — no meat, dairy, eggs, honey, beeswax, lanolin, carmine, gelatin, silk, or other animal-derived substances.
In personal care and cosmetics, "vegan" is distinct from "cruelty-free": a vegan product may still have been tested on animals unless it also carries a cruelty-free certification, and a cruelty-free product may still contain animal byproducts.
Reliable third-party vegan certifications include The Vegan Society's trademark, Vegan Action's Certified Vegan logo, and PETA's Vegan mark.
