People and planet are everything to us. We want to show you that we walk our talk.

Sustainability is at the centre of everything we do. Sienna leads the way in best practice for nail polish quality, production and formula, and we will keep pushing forward to inspire a sustainable, ethical approach to beauty. Everything starts at the polish. How can we create the best formula? How can we do the best by our planet, and our people?

We innovate to find effective, eco-friendly, safe alternatives.
neutral nail polish bottles with timber cap by Sienna

Sienna is 100% vegan and cruelty free with the certifications to prove it. This is core to our product. We will never sell our polish in markets that require animal testing.

When it comes to our formula, Sienna is not only vegan, cruelty free, non-toxic, Benzo-free, and breathable but we are now the first glitter free, aluminium free and nano-particle free nail polish in the world. Even more exciting, our new plant based formula includes ingredients with little to no waste by-product. We’re talking about raw ingredients including sugar cane, manioc (cassava), cotton and corn.

Our nail polish remover is water based with added soy and vitamin E. It is free of any nasties.

We use 100% renewable energy at our head office and warehouse. We source all power from an ethical company with strong environmental and community credentials.

Our production happens direct with our raw ingredients manufacturers in France, Europe. By working direct with this green industry manufacturer we keep our carbon footprint low.

Packaging is 100% recyclable and we run an in-house recycling program so customers can return their empties.

Rather than use an unnecessary plastic cap, we use timber. Our signature caps are hand crafted from a local, non-native weed wood. We work to keep local rainforest areas free from this pest and allow native revegetation to flourish in its place.

Not only is our timber organic, it is compostable and a beauty to upcycle. We’re also big on recycling here at Sienna. Recycling Sienna bottles when they are empty is very straightforward. The timber cap can be put straight into your compost bin where it will break down organically. The plastic brush and glass bottle needs to be cleaned with nail polish remover to make sure they are free of any excess residue. Then, simply place the bottles in your recycling. In terms of the brushes, not all recycling centres will accept the brushes, so it’s best to check with your local facility first. If you are in doubt or unable to recycle either the bottles or brushes, please return them to us and we will add them to our in-house recycling program.

Beauty is for everyone.

Rafiki Mwema

Rafiki Mwema is a non-profit organisation created by two pioneering women, Anne-Marie, from the UK, and Sarah, a local from Lennox Head near Byron Bay. Together they raise money to help young sex abuse survivors from Kenya to live safely and understand their frightening experiences. The situation these young children face is horrific and we want to help in any way we can. As part of this commitment, we donate each month to sponsor a child in their care in Kenya, ‘Elizabeth’. We were able to take our efforts a step further recently, collaborating with Rafiki to create a fundraising three-pack of Sienna polishes, with all profits from the sale of this pack to be donated to Rafiki Mwema.

“I always wanted Sienna to be a beauty brand that gives back. I’m so proud for us to be partnering again with Rafiki Mwema. The kids they love, care and advocate for have gone through so much, it’s just not fair. The work Rafiki does to heal their trauma and keep them safe is so important.”

— Danielle, Sienna Founder and Creative Director

Update: We are so very proud to announce that sales from the (now sold-out) Jamii pack raised $3226.86 in cash plus we donated 25 Jamii packs for them to sell on their website bringing the total donation to $5k for Rafiki Mwema! We are so proud and grateful to all our beautiful customers who really embraced this campaign.
