Easy ordering at your fingertips
Luxe, minimalist, and high-quality without compromises.
From a coastal paradise where golden beaches meet turquoise waves, we've brought that magical, breathtaking canvas of nature's artistry to 20 countries worldwide.
Byron Bay is the muse behind each shade you get from Sienna, backed by high quality formulas that keep each colour’s genuine vibrancy and durability – much like the seaside haven itself.
Sienna lets your true self take the spotlight, painted through an expansive array of shades, each with its own unique trait, character, and spirit.
Sail through the calming blues that whisper serenity, embrace the timeless allure of nudes tinged with blossoming pinks, or let your passion blaze in the enchanting reds. The journey is limitless, and the choices are boundless.
Beyond clean aesthetics lies the core of Sienna's formulations: a blend of advanced green science, sustainable production and distribution, plus renewable plant-based ingredients. We proudly claim the title of the world's first glitter and nano-particle-free nail polish.
But our products stand for more than just an absence of chemicals – they embody a commitment to a purer, more sustainable, and more conscious way of loving yourself.
Treating you and the planet with the utmost care
We use plant-based ingredients with minimal waste, offer 100% recyclable packaging, and run an in-house recycling program.
Being vegan and cruelty-free covers all bases. No animal products in our polish, and definitely no animal testing, we’re committed to both!
The first of its kind worldwide, with no nano-particles, benzophenone 1, or any of the harmful ingredients everyone avoids.
40 researchers exclusively specialised in nail polish work their magic every day in our sustainable lab to produce your favourite Sienna shades.

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 both air and water 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..
