What our happy customers say

Sienna love around the world.

“Everyone asks me where I found this unique, beautiful and very useful shade of the nail polish. This colour honesty goes with so many colours of your clothes, shoes and bags. I'm so happy to have it. Excellent quality like all Senna products I've already tried.”

“When I first tried the colour I didn’t really like it as I’m more into neutrals. It’s now my favourite, so much so that I haven’t opened any of my other bottles! I think the colour holds better than other popular brands, still around one week.”1

“Sienna makes the most stunning coloured nail polishes. I loved this trio. It was the first three nail polishes I used from my order. Colours are great! Nail polish consistency is amazing, only need 1-2 coats and spreads nice on the nail.”

Frequently Asked Questions

We’ve got you covered. Find answers to all questions.

Did you know that a company can be vegan but not cruelty-free? Confusing isn’t it! Cruelty-free refers to not testing on animals, whereas vegan means not including animal or animal by-products within ingredients.

Sienna nail polish is proudly both vegan certified and cruelty-free (woohool!) and is accredited by Vegan Society & Peta (Beauty without bunnies program) which are all auditing bodies who verify the high standards we set for ourselves. We created our entire range so that you can have peace of mind that our products are of the highest quality for you and don’t harm our animal friends.

When non-toxic nail polish arrived in the market, the ‘X-free’ branding was used to show customers the number of chemicals a polish is ‘free’ from.

Unfortunately, without a regulatory body for this type of branding it is fast becoming a race to include as much as possible in the ‘x free’ calculation and some brands have started including ingredients that are not commonly found in nail polish. Therefore, we have decided to not label and let our ingredients list do the talking. We go into this in more depth in our 10-free, 12-free nail polish explained blog.

So don’t be fooled by a big ‘x-free’ number. Take a look at each brands formula to ensure you’re getting a true natural and non-toxic nail polish.

Sienna stands strongly by our formula and is proud to be a natural and non-toxic nail polish brand that is the cleanest brand on the market globally.

We have always been free of formaldehyde, dbp, toluene, tosylamide/formaldehyde resin, synthetic camphor, xylene and benzophenone -1. We are also accredited by the safe cosmetics australia (the toxic-free campaign) and our mission is to ensure that our formula supports your health, planet and your manis!

And if you still don’t take our word for it, we are certified by made safe who have analysed every single ingredient and deemed us the cleanest. Simply put, we want you to be able to enjoy luxe, high-quality natural nail polish that’s free of nasties and available in a beautiful range of organic colours. What more could you want?

Yes! We are halal certified by halal certification services and our nail polishes are independently tested to be breathable and water permeable through osmosis.

Our polish has been scientifically tested to ensure osmosis occurs all the way through to the nail bed itself. Note this is not visible to the naked eye and the commonly used coffee paper saturation tests are not accurate. Osmosis happens through gently permeating the nail polish film so your nail bed will be touched by water.
