FAQs

Les questions les plus fréquemment posées par nos utilisatrices et notre communauté !

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.

Can I use a treatment base coat under Green Flash™?

For maximum staying power, we recommend that you only use Green Flash™ Base Coat.

Can treatment base coats be removed with Green Flash™ Nail Polish Remover?

All our treatment base coats can be removed like our polish - with our Nail Polish Remover or Green Flash™ Nail Polish Remover.

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 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.

This has definitely helped me

"This has definitely helped me not bite my nails! The taste is bitter and unpleasant, as it should. It doesn't transfer to e. g. , food if I'm cooking or eating. I also like that it has ingredients that help the nails grow stronger and healthier. Obvs doesn't fix the reasons I bite my nails (anxiety, stress), but reminds me to opt for better coping mechanisms!"

— Outi I. (5/5)

Amazing product through and through!

"Amazing product through and through! I'm all for natural nails but unfortunately my own nails are quite uneven, dull and thin. And this care polish checks all the boxes. It's staying power is no joke. I did my nails a week ago and went on an active holiday and it's still looking as good as new. No chipping or peeling. It gives my nails a very natural powdery satin look and actually fortifies them. Even one coat looks great and instantly improves an overall look of the nails."
