How to?

How to use the Xtrem Flash™ Top Coat?

After applying and curing 1 coat of Green Flash™ Vitaminized Base Coat and 2 thin layers of Green Flash™ colour, apply a thin layer of Top Coat on 4 flat fingers (excluding the thumb - to prevent the gel texture from slipping into the cuticles and causing the manicure to lift prematurely).
Cure under LED Lamp (Top Coat program).
Repeat for the thumb separately, keeping it flat, then cure.
The Xtrem Flash™ top coat does not require a primer, nor wiping after curing !

How to remove the Xtrem Flash™ Top Coat?
No drilling nor acetone needed!

Cut small cotton pads and soak them completely with Green Flash™ Acetone-Free Remover and secure them for 10 minutes using Removal Clips.
The polish lifts off easily in peel-off form. Remove any residue gently with an wooden stick.

Astuce de pro ✨

Once you’ve mastered the technique, and if your nail length allows it: carefully cap the free edge of the nail before curing, without adding more polish, by gently gliding the brush along the tip. This step helps seal the different layers together, ensuring better waterproofing and longer wear for your manicure.

Reviews

Bien mais pas top

"Très beau brillant, c'est certain mais il faut vraiment apprendre à le mettre parce que pour ma part, les premiers essais n'ont pas été concluants. Le vernis se détache et ne fait pas du bien à l'ongle. Je vais retenter ou alors retourner à mon top coat classique que je maitrise mieux pour le coup"

— Anaïs (3/5)

Tenuta e brillantezza eccellenti

"Felicissima di aver provato questo nuovo top coat. La brillantezza è rimasta intatta e anche lo smalto è durato tantissimo. L’ho dovuto rimuovere dopo 10 giorni perché le mie unghie erano cresciute troppo, ma avrei potuto tenerlo tranquillamente. Unica pecca: c’ho messo tantissimo a rimuoverlo! Magari la prossima volta provo a limarlo un pochino prima"

— Val (5/5)

This is the one to get

"This top coat finally makes Manucurist a proper alternative to regular UV polishes in terms of longevity and shine. My mani held up beautifully for 2 weeks, with only the tiniest chips here on two nails, and still smooth and shiny. Could have keep it on longer easily, if not for regrowth. 10/10."

— Ania (5/5)

A total game changer

"I liked my Green Flash system before, but this top coat makes me LOVE it. Some of my complaints before were that every application looked streaky no matter how many coats I put on and they didn’t always last longer than a week, but because of the quick application and removal, I was willing to put up with it. This top coat solves all of the problems I had before; the plumping effect makes my coats look more even and I can get two weeks easily out of my nails, now! The photos I’ve included are after two weeks of wear. I highly recommend this product!"

— Cheyenne S. (5/5)

Top coat extra

"Top coat incroyable pour ma part. Il tient bien une bonne quinzaine de jours jusqu à 20 jours sans problème et sans s écailler. Et il garde sa brillance jusqu au bout. Petit bémol, juste très long à retirer mais à part ça, il est extra vraiment 😁"

— Sabrina (5/5)

Je mettais tous mes espoirs

"Je mettais tous mes espoirs dans ce top coat car le classique ne tient jamais plus de 2 jours sur mes ongles. J’essaie pourtant de bien border le bout mais dès le lendemain certains s’écaillent. L’Xtrem a un rendu très joli, avec une brillance qui dure mais au bout d’1 jour et demi ça s’écaille déjà… Pouces, index et majeurs, sûrement ceux qui prennent le plus de chocs. J’ai pourtant essayé les soins ongles striés et bases fortifiantes pour les renforcer et améliorer la tenue mais pas mieux. Dommage car j’adore le principe et le rendu juste après la pose mais pour 2j ça fait long en temps de pose et un peu cher!"

— Amelie V. (3/5)

Un super top coat, hyper

"Un super top coat, hyper brillant, qui protège bien les ongles - ici manucure à J+5. La pose est un peu plus délicate qu'avec la version classique mais le coup se prend bien et la dépose se passe nikel."

— Stéphanie L. (5/5)

Très bon top coat qui

"Très bon top coat qui tient bien mais qui demande une bonne maîtrise. Le vernis dois être appliqué en couche très fine en dessous pour ne pas s'écailler et une toute petite goutte de top coat suffit ! Le manuel explique bien qu'il faut au moins 3 utilisation pour avoir un bon résultat"

— Cécile D. (5/5)

Très contente de ce top

"Très contente de ce top coat ! Sur les photos c’est le résultat après 2 puis 3 semaines. Le rendu est vraiment joli, on se rapproche beaucoup du rendu que l’on obtient en salon, et je dois reconnaître que le vernis a bien tenu puisque je le porte depuis 3 semaines 🙏"

— Amelie C. (5/5)

Super ! La brillance tient

"Super ! La brillance tient plus longtemps, et est bien plus résistant que l’ancien top coat qui ternissait assez vite finalement. Maman de 4 enfants mes ongles sont mis à rudes épreuves ! Petit bémol à noter : Plus difficile cependant à appliquer pour un rendu lisse, il faut vraiment avoir le coup de main et mettre la juste quantité (ce top coat plus tendance à friper). Pour ma part j’ai toujours 1 ongle sur 10 à refaire à chaque fois."

FAQ

Our Frequently Asked Questions from our customers and community!

What is Xtrem Flash™?

Xtrem Flash™ Top Coat is a long-lasting gel top coat that adds shine and strength to your manicure for up to 21 days. Its innovative formula combines a high-performance gel effect with express removal without the need for drilling or acetone.

What is the difference between Xtrem Flash™ Top Coat and Green Flash™ Top Coat?

Green Flash™ Top Coat is a gentle top coat with a natural formula that gives your manicure a natural shine, lasts for up to 12 days and can be removed in 1 minute with Green Flash™ acetone-free nail polish remover.

Xtrem Flash™ Top Coat is a gel top coat that lasts for up to 21 days, gives your manicure an intense shine and curved finish, and can be removed in 10 minute with Green Flash™ acetone-free nail polish remover. Xtrem Flash™ is the perfect choice for anyone seeking a long-lasting manicure with a finish similar to professional gel that does not need to be removed using drilling or acetone.

Is Xtrem Flash™ Top Coat compatible with the Green Flash™ range?

Yes! Xtrem Flash™ has been specially designed to be used in conjunction with products from the Green Flash™ range: base coat, colours, lamp and nail polish remover. No need to buy more products to upgrade your manicure!

How do I apply Xtrem Flash™ Top Coat?

Apply your Green Flash™ nail polish in the usual way (base coat, colour + cure under a Manucurist LED lamp). Instead of your Green Flash™ Top Coat, apply an even coat of Xtrem Flash™ Top Coat to 4 fingers (excluding your thumbs), then cure under an LED lamp using the Top Coat programme. Repeat on your thumbs, keeping them nice and flat. The result: a durable, ultra-glossy finish that dries instantly and lasts for up to 21 days!

Is Xtrem Flash™ Top Coat difficult to remove?

No, that's Manucurist's trademark! You can forget all about drilling, which severely damages your nails. Unlike traditional gels, Xtrem Flash™ can be removed by peeling it off, after leaving a cotton pad soaked in Green Flash™ acetone-free remover under your nail clips for 10 minutes. The result: your nails stay strong, even after removal.

My nails are damaged and prone to splitting. Is Xtrem Flash™ suitable for my nails?

Xtrem Flash™ has been designed for soft, damaged nails that cause polish to chip quickly! Replace your Green Flash™ Top Coat with Xtrem Flash™ Top Coat for some or all of your manicures to make them last twice as long, giving you up to 21 days of shine and staying power. And removing it is just as easy!

Why has my Xtrem Flash™ manicure lifted at the sides?

This can happen if your Xtrem Flash™ Top Coat spreads to your cuticles or side edges during application. When the product touches the skin, it does not adhere to the nail properly and this can cause it to lift. To avoid this, push back your cuticles before your manicure, and always leave a narrow margin between the polish and your cuticles and nail edges.
