STELLA CHROMA polishes are big five free, cruelty-free, and paraben-free. That means NO Camphor, NO Dibutyl Phthalate (DBP), NO Toulene, NO Formaldehyde, NO Formaldehyde Resins, and no components are tested on animals. Polishes are tested extensively before release. All are hand-mixed in small batches at our facility. We follow specific recipes for each lacquer, but slight variations may still occur.
