The design of the brand is beautiful and the selection of nail polish colours to die for. The already iconic long-lasting natural lipsticks are a Nourished favourite. Kester Back nail polish is 12-Free™ which means they strips out a lot of bad stuff. While no nail polish can ever be fully free of chemicals, their 12-Free™ brand does not contain formaldehyde, toluene, DBP, camphor, formaldehyde resin, xylene, parabens, fragrances, phthalates, ethyl tosylamide, triphenyl phosphate and animal derived or tested ingredients.
