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.

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.
