Nail Polish Sienna plant based nail polish formulas use raw, sustainable ingredients including sugar cane, cassava, cotton and corn. Building on their pioneering vegan, cruelty-free, non-toxic formula, Sienna are now the world’s first, nano-particle free nail polish, that’s healthy for people and the planet too.*As you know Sienna holds a high standard when it comes to what we do and don't use in our products. We try to avoid nano particles in all products as they are adverse to optimum health. One key ingredient in black nail polish is a colourant called 'nano-black' and is, you guessed it, made using nano particles. Because we do our best to avoid this, we instead make Onyx using alternative colourants and so you may need 3 coats to achieve a full coverage to the nail.
