A note from our founder
Thank you so much for joining the Sienna community. When I first launched Sienna, I never imagined we would be here: launching a new global-standard in clean, plant-based, luxury nail polish.

Everyone who has bought or received a Sienna product or interacted with us on social media demonstrates that there is value in innovation, sustainability, health and, of course, a great mani. Each one of you has inspired us to keep pushing forward to bring you an ethical and sustainable clean nail polish. Our new formula is for you. We went all over the world to find and refine this formula, and are so proud to offer a luxe, modern nail polish aligned with our values of respect for people and planet.

Our new formula is the cleanest yet. You will find renewable, plant-based ingredients on our ingredient lists from now on – right now there is corn, cassava, sugar cane and cotton. This is a luxurious experience powered by plants. Of course, we are still vegan, cruelty-free, breathable, inclusive and free from Benzophenone -1 and micro-plastics. But by committing to continual innovation, we have been able to take a step towards an even greener polish by removing aluminium and nanoparticles. We’ll never give up in our quest to create the best possible polish for the Sienna community. We hope you love this new formula as much as we do.

With gratitude,
Danielle – Creative Director and Founder
