Acquarella Nail Polish

Acquarella offers non-toxic, water-based nail colors that are vegan and free of solvents, phthalates, aromatic hydrocarbons and even wheat byproducts for the gluten intolerant. Plus, they require no top or base coat, but it helps to buff the nails first; otherwise, end results may be disappointing or chip. The entire brand has a low hazard rating in the Skin Deep Database.
