How do I store my Kester Black Nail Polish?
Nail polish should always be stored in a cool dark place. Do not store nail polish in the fridge. Temperature variation i.e the fridge and extreme heat, will cause damage to the formulation, resulting in gluggy varnish or colour separation. Storing nail polish in direct sunlight will also change the colour of the polish.

What is the shelf life of my nail polish?

You will be happy to hear that Kester Black nail polish has an unlimited shelf life. If colours separate  when not in use, simply shake the bottle well to re-mix.

Does Kester Black nail polish contain Palm Oil?
No. We are proud to say that all of Kester Black products are palm oil free. Finding alternatives to natural commodities such as palm oil is very important to us. wW learned that approximately 300 football fields of forest are cut down each hour to make way for palm oil plantations. From rapid rates of deforestation and habitat degradation, to human rights and indigenous land injustices; it became crystal clear to us that palm oil production promotes very severe environmental and social impacts.

But doesn’t glycerine come from Palm Oil?

No, we use a glycerine that is coconut-based, which means its environmental impact is minimal compared to traditional glycerine production.

2. Apply a thin layer of basecoat. Allow to dry.
3. Apply a thin coat of nail polish. Allow to dry. Repeat for a second coat.
4. Finish with topcoat. Cover the tip of the nail to avoid chipping.
5. To prolong your new manicure, apply topcoat to the tip of the nail every two days.
6. Enjoy the compliments!

Why do fluos need 3-coats?
In making non-fluorescent colours, we start with a white base and add pigment. In making Fluro colours, we have to start with a clear base and add the pigment to that, which makes everything a little different. Because the fluro colours are not able to contain any white base, they require a few more coats to cover the nail and become opaque. If they did contain a white base, they wouldn’t be fluoro, they’d actually become pastel.

How do I save my gluggy nail polish?
You must use nail polish thinner to restore your nail polish back to new. A few drops will do. Never ever use nail polish remover to thin your polish, it will ruin it a month or so later.
