Reviews

I love this basecoat! It

"I love this basecoat! It leaves a gorgeous shine and it stays on for so long. Normally anything peels off within days for me but this stays on quite well (ofc it helps that it's transparent). I also feel like my nails feel stronger and healthier from the first day that I've been using it. It's also great in combination with nailpolish, but I do notice some chipping then. But it's defenitely my go-to when I want healthy shiny natural looking nails!"

— Eva S. (5/5)

Base SOS + glass buffer = game changer

"Didn’t expect this result! I had heard that a glass buffer is ideal for peeling nails, but I didn’t expect such a result! I used it, applied a layer of Base SOS, and they look better than ever."

FAQ

Our Frequently Asked Questions from our customers and community!

Can I use a treatment base coat as a base coat for my Green™ or Green Flash™ polish?

Treatment base coats can be used as a base coat as part of your Green™ manicure.

However, they cannot be used instead of a Green Flash™ base coat, which needs to dry under the lamp.
How many coats of treatment base coat do I need to apply?

A single coat is enough.
If I want to apply more treatment base coat, should I remove the old coat first?

When using a treatment base coat, there's no need to remove the previous coat.
Can I use a treatment base coat under Green Flash™?

For maximum staying power, we recommend that you only use Green Flash™ Base Coat.
Do treatment bases come off with Green Flash™ remover?

All treatment bases remove like our polishes, with our Dissolving Oil or our Green Flash™ remover.
What nail care products are best suited to my nail type?

Every nail type is different! Complete our online nail analysis to help you select the most suitable nail care products.

We can then offer you a nail care programme tailored to your needs!
What is the difference between the S.O.S. Base Coat and the Force Base Coat?

The S.O.S Base Coat is designed for brittle nails weakened by external aggressors, e.g. frequent use of gel nail polish, excessive drilling or filing, overexposure to chemicals, etc. The Force Base Coat is for soft nails that tend to flex or bend easily.

Can pregnant and/or breastfeeding women use your nail care range?

Our nail care formulas are green and clean: they are up to 99% plant-based, i.e. made from biomass ingredients like aloe vera, lemon, ginseng, pomegranate and grape. However, women should avoid all types of nail polish when they are pregnant or breastfeeding. We recommend you speak to a healthcare professional if you are unsure.
Can using your nail care products cause allergies?

Our nail care formulas meet European standards and do not contain any sensitising substances. They are also certified gluten-free and safe for people with gluten intolerance or celiac disease, as are our Green Flash™, Green™ and Active™ ranges. Most customers who are allergic to regular nail care products are not allergic to the Manucurist nail care range. However, as allergic reactions are not specifically linked to chemical ingredients, they can sometimes occur with plant-based ingredients. We recommend you speak to a healthcare professional if you are unsure.

For more information, see our blog on allergies.
