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?


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.

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.

Sienna was the first Australian polish to be completely free of Benzophenone -1. Our formula is proudly non-toxic and we are the cleanest nail polish on the market, globally. We were also the first nail polish company to ban the micro-plastic, glitter, from all production.

We innovate to find effective alternatives. Our nail polish remover is based on soy beans and is completely free of any nasties.

Our production happens within Australia to keep our carbon footprint low. In fact, most within 100kms of our warehouse.

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

Printing is 100% local on recycled stock.


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.

We source all ingredients for Sienna from organisations that are child labour free – and we always will.

We invest in our communities by sourcing locally and giving back.

We partner with local charities like Future Dreamers and continue to support Rafiki Mwema through an ongoing sponsorship.

Beauty is for everyone.

Our collections are gender-inclusive. Our formula is water permeable and Wudu-friendly, which means it is suitable for people of Muslim faith. No-one gets left behind.


We believe in doing business differently. We want to be a force for good in the world. Our values are important to us. Sienna is very proud to be accredited by the following independent, internationally recognised auditing bodies who verify we meet the high standards we set for ourselves.

B Corporation

Sienna is extremely proud to be a certified B Corporation. Certified B Corporations meet the highest standards of verified social and environmental performance, public transparency, and legal accountability to balance profit and purpose.

Safe Cosmetics Australia

(the Toxic-free campaign)

Acting as a consumer voice and third party for brands, SCA is continually campaigning the beauty industry to exclude and restrict potentially harmful chemicals from their products. Safe Cosmetics Australia is calling all brands to provide ingredient transparency and to leave out chemicals that are known to be toxic or associated with triggering allergies and skin irritation. Products certified as Made Safe have been assessed as being without these problematic ingredients.

Australian Made

The Australian Made campaign is designed to inform consumers where products and their ingredients come from. When you purchase Australian Made, you are supporting your local community, building the Australian economy and putting more Australians in jobs. Sienna is manufactured from start to finish in locally in Australia.

Choose Cruelty Free Australia

Choose Cruelty Free is an independent, non-profit organisation based in Australia. They actively campaign to end testing on animals and have in place very strict criteria when assessing companies for accreditation. Products with this logo are certified cruelty free – they have-never and will never test on animals, nor do they pay a third party to do so.

Vegan Action


Vegan Action is a non-profit organisation and is one of the oldest and most visited vegan websites in the world. The certified logo ensures products do not contain animal products or by-products and have not been tested on animals.


(Beauty without Bunnies program)

People for the Ethical Treatment of Animals (PETA) is the largest animal rights organisation in the world. The Beauty without Bunnies program ensures products are never tested on animals.

Who we support

We believe in giving back to the community and we want to be helpful. Sienna is committed to giving a platform to charities and organisations doing great work.

Stay tuned for more collaborations… coming soon!

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.

Every month, we give Rafiki Mwema a donation to sponsor ‘Elizabeth’ – a child in Kenya. The situation these young children face is horrific and we wanted to help as much as we could.

Futur Dreamers

Future Dreamer Girls Club is a safe, uplifting and interactive space for girls and women to be supported. The club offers a range of age-appropriate, specifically designed activities and events to inspire, connect, challenge and celebrate. So far, over they’ve had 4740 girls through the doors of their HQ in Byron Bay.

We worked with Future Dreamers to create a gorgeous limited edition turquoise pearl polish, with all profits going directly to the clubhouse and the programs they run.

We also ran a workshop with the passionate Future Dreamers team and 30 energetic, 11 year old girls at their HQ. You can read more about the fun on our blog, Sienna X Future Dreamers.
