Consider this vegan base coat the healthier alternative to prolonging polish adhesion. Boasting an 8-free formula—meaning it doesn't contain dibutyl phthalate (DBP), toluene, formaldehyde, formaldehyde resin, camphor, ethyl tosylamide, xylene, or triphenyl phosphate (TPHP)—the base coat helps to increase nail strength, repair soft or peeling nails, and prevent cracking while acting as a ridge filler.
