Sienna Byron Bay Nail Polish – Top & Base Coats + Ambrosia and Seeker

One of my greatest finds in the past few months has been coming across the nail polish brand Sienna Byron Bay. I briefly mentioned that I had purchased some in this post here, and for the past few months I’ve worn nothing on my nails but Sienna polishes. They are non-toxic, 7-free and are about as safe as you can get when it comes to nail polish. They have a stunning range of colours and I actually want to own every single colour in the collection. Today I thought I’d share with you my thoughts on the Base Coat, Lightening Top Coat, and two shades – Ambrosia and Seeker.


Sienna Byron Bay are one of those companies you can just tell are genuinely passionate about what they do. Their products are lovingly handcrafted and hand poured, and they strive to be as eco-friendly as possible. The beautiful wooden tops on the polishes are not only unique, but are created from sustainable timber, from forests only 10 minutes away from Byron Bay. The majority of their ingredients are sourced in Australia, ensuring the carbon footprint from creating their products are as minimal as possible. They are also one of the very few brands that are truly non-toxic, with seven chemicals (including  Benzophenone-1) removed, making them a much safer alternative to regular nail polish. As well as all of this, all of their polishes are vegan and cruelty free. I found the “about us” section of their website really interesting and inspiring, so if you’d like to see more of their story, then make sure you check it out.

Sienna Byron Bay now offer a huge range of colours and finishes, as well as a Base Coat and a Lightening Top Coat. While it’s not necessary, I always use a base and top coat to extend the life of my manicure and to ensure there is no staining of my natural nails.  All four of the polishes I’ve tried are much less smelly than regular polishes. While they do still have a slight nail polish smell, it is much much less than brands such as essie or OPI.

The Base Coat is aqua blue in colour, and is actually formulated to be a ‘sticky’ base coat. This means that it adheres to the nail and has a slightly rougher feel and finish to it which helps the coloured polish to adhere properly. This helps to ensure the polish lasts the longest time possible. Once on the nail, this base coat appears clear with a slight shine to it, and it can actually be worn alone as a clear nail polish.


The Lightening Top Coat is a clear top coat with a beautiful glossy shine to it when it dries. It’s a slightly thicker formula than others I’ve used before – almost more like a gel finish top coat – and I’m guessing it’s this that gives the gorgeous shine. It does dry quite fast, and my nails are dry to the touch in about 3-4 minutes. I always like to leave my nails to dry longer just to ensure nothing ruins my handiwork! I really like this top coat, although you do have to work fairly quickly to get an even application as it does start to dry almost instantly. The first time I used it, I made the mistake of applying it in front of the heater – the warmth made it dry super quickly and it became blotchy on top of the nails. Now I do it in a slightly cooler area.

The shade Ambrosia is a medium soft pink, and it’s an absolutely beautiful shade. It’s very versatile and is one of those colours that you can wear anywhere and pair with anything. It has a crème finish with no shimmer, and while I generally prefer a shimmery nail polish, I have to say I really do love this shade. The polish itself is more opaque than I had expected and while I still did two coats of colour, I really could have gotten away with one. The polish is very even and any streaks disappear as it dries. I noticed a little bit of chipping on the fourth day of wear, and I removed the colour on the fifth day.


As soon as I saw it on Sienna Byron Bay’s Instagram page, I knew I had to get the shade Seeker. It’s a stunning deep amethyst shade that has the most gorgeous golden shimmer through it. It’s a really unique colour and I think it’s probably my favourite nail colour of all time (and that’s a pretty big claim!). It looks absolutely beautiful on the nails, and I’ve had so many compliments wearing this one. This shade definitely needs two coats to build up and even and deep colour –one coat just looks a little patchy. I’m not sure if it’s just the difference in shades or the difference in the finishes, but Seeker wore for a day or two longer than Ambrosia. Perhaps the shimmer finishes wear slightly better than the crème formulas. I’ll have to test this one out with some more shades  😉

Overall, I’m thoroughly impressed with the Sienna Byron Bay nail polishes and I’ve been adding more to my collection. I’ve actually gotten rid of all my other brands of nail polish, and this is the only brand I use now. Nail polish is something I couldn’t part with, so I’m really happy to have discovered this non-toxic alternative. If you’re looking to purchase these polishes, the best place to get them from in NZ is The Rock Box (for the cheapest NZ shipping) or if you’re in Aussie try the official site.

    Hi there!
    I haven’t played around with nail polish for a long time but I’m keen to get back into it and really like the look of the sienna polishes. I’m hesitant to buy a colour, base coat and top coat because of the price, do I need the base and top coats? Thankyou!

      Hey Lauren! I really like using a base coat with darker colours so it doesn’t stain your nails, but if you’re wanting a softer colour then you could totally skip the base coat. The top coat extends the wear by one or two days, but again, you don’t really need it 🙂
