FAQs

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.

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.

Super produit qui permet un

"Super produit qui permet un séchage rapide en laissant le contour de l'ongle hydraté et permet d’atténuer l’odeur des vernis à ongles"

— Anne G. (5/5)

I've been using this again

"I've been using this again for the last couple of months. I'm sure it's helping but my nails are so weak and damaged from nail bars I can't expect miracles and realised my nails probably needs to grow out Atleast 3-4mm to show the healthier, stronger nail. I've been using polygel wraps, but these are unsuccessful due to the bendyness of my nails so I am swapping to The Manacurist Green flash LED range to treat my nails and protect them. I will give my nails a weekly treatment of SOS and keratin and night masque treatment before reapplying the polish using the vitamin base. Hoping in 3-6m9ntus my nails show distinct improvement. I trust the manacurist range and have used it on and off over the last year."

— Louise R. (5/5)

La base semble efficace :

"La base semble efficace : en 1 utilisation, j’ai trouvé que mes ongles étaient plus solides, durcis. Je parle de l’état de mes ongles après avoir enlevé le vernis soin SOS au bout d’une semaine."

"Mi trovo molto bene con questa base. In effetti rinforza le unghie e mi sta aiutando molto a farle ricrescere sane dopo una manicure sbagliata."

If you need stronger nails. . .

"This is one of those products you didn't know you needed until you try it. It took me about 3-4 uses of Base S. O. S. and my nails are now visibly healthier and they feel significantly more strong/firm. I have been able to actually grow them out to a few millimeters with this miracle product. Base S. O. S. I use both as a base under the green polish and by itself, about twice every 10 days. I will continue to use as long as it exists!"

— Kathleen (5/5)

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."

— Niki (5/5)

Je suis très satisfaite de

"Je suis très satisfaite de cette base SOS. Mes ongles étaient fragiles, cassants et abîmés, mais après quelques semaines d’utilisation, j’ai remarqué une nette amélioration. Ils sont plus forts, plus résistants et ont retrouvé un aspect plus sain. La texture est agréable, l’application est facile et le produit sèche rapidement. J’apprécie également sa composition de qualité. C’est devenu un indispensable dans ma routine de soin des ongles. Je recommande vivement cette base à toutes les femmes qui souhaitent renforcer et réparer leurs ongles."

— Dominique P. (5/5)
