New York natives, Nadine Abramcyk and Adair Ilyinsky, founded Tenoverten salons and nail polish in response to the lack of nontoxic beauty parlor options in their Tribeca neighborhood. Their cruelty-free, vegan, and non-toxic polishes are formulated to promote stronger, healthier nails and each shade pays homage to their home town with its name after a Manhattan street. All Tenoverten products are made in the USA and 8-free without any formaldehyde, dibutyl phthalate (DBP), toluene, formaldehyde resin, camphor, ethyl tosylamide, xylene, or triphenyl phosphate (TPHP).
