Their story starts in 1991, when a team of visionary beauty experts developed SinfulColors for professional beauty stores. Their ability to anticipate the next “now” colors made an instant splash. In no time, SinfulColors spread it's on-trend color appeal through retail stores and across the country. What also makes SinfulColors such a runaway favorite is that our nail polishes are incredibly affordable, cruelty-free and formulated with quality ingredients.
