Sienna is a conventional vegan nail polish formula. It offers a cleaner and more natural option compared to other brands.

Glitter has a significant environmental impact, and we stand against that. Microplastics from glitter have been documented to harm marine life, causing seabirds to die of starvation when ingested. Sienna was the first nail polish brand globally to ban glitter from production to address the environmental concerns.

Our nail polish allows air to permeate through the surface. Scientifically tested to ensure osmosis occurs all the way to the nail bed.

Please note that this osmosis is not visible to the naked eye, and
commonly used coffee paper saturation tests are not accurate. Osmosis happens through gently permeating the nail polish film.
