How to?
How to use the Top Coat Xtrem Flash™?
- After curing one coat of Green Flash™ Vitamin Base Coat and 2 coats of Green Flash™ colour, apply a thin coat of Top Coat Xtrem Flash™ across 4 flat fingers (excluding the thumb – to prevent the gel texture from running into the cuticles and causing premature lifting of the manicure).
- Cure under the LED Lamp (Top Coat preset).
- Do the same for the thumb separately, keeping it flat, then cure.
No need to primer, and no need to wipe the top coat after curing!
How to remove the Top Coat Xtrem Flash™?
No buffing and no acetone!
- Cut small cotton pads, soak them completely in Green Flash™ Acetone-Free Nail Polish Remover, and hold them in place for 10 minutes using the Removal Clips.
- The polish peels off easily. Remove any remaining residue with a wooden cuticle stick.
Pro tip ✨
Once you've mastered the routine and become a Green Flash™ expert—and if your nail length allows: carefully cap the free edge of the nail when applying the top coat before curing, without picking up extra polish, by gliding the brush along the tip. This seals the layers together and ensures better water resistance and wear time for your manicure.

FAQ
The most frequently asked questions from our users and community!
What is Xtrem Flash™?
Xtrem Flash™ Top Coat is a long-wear gel top coat that delivers up to 21 days of shine and resistance for your manicure. Its innovative formula combines high-performance gel effect with express removal — no filing, no acetone.
What is the difference between the Xtrem Flash™ Top Coat and the Green Flash™ Top Coat?
The Green Flash™ Top Coat is a gentle top coat with a naturally derived formula, giving your manicure a natural glossy finish, wear of up to 12 days, and it can be removed in 1 minute with the acetone-free Green Flash™ Remover.
The Xtrem Flash™ Top Coat is a gel top coat that offers wear of up to 21 days, an intense high-shine domed finish, and can be removed in 10 minutes with the Green Flash™ Remover. Xtrem Flash™ is the ideal option for those looking for a long-lasting manicure with a finish close to professional gel, but without filing or acetone for removal.
Is the Xtrem Flash™ Top Coat compatible with the Green Flash™ range?
Yes! Xtrem Flash™ was specially designed to work with the Green Flash™ range: base, shades, lamp, remover. No need to buy everything again to upgrade your manicure!
How to apply Top Coat Xtrem Flash™
Apply your Green Flash™ polish as usual (base, colour + flash under Manucurist LED lamp). In place of your Green Flash™ Top Coat, apply an even coat of Top Coat Xtrem Flash™ to 4 fingers (excluding thumbs), then flash under the LED lamp on the Top Coat setting. Repeat for the thumbs, keeping them flat. The result: an ultra-glossy, instantly dry and durable finish that lasts up to 21 days!
Is removing the Xtrem Flash™ Top Coat difficult?
No, that's Manucurist's signature: forget filing, which seriously damages nails! Unlike traditional gels, Xtrem Flash™ is removed peel-off by leaving a cotton pad soaked in acetone-free Green Flash™ Remover under removal clips for 10 minutes. Result: nails stay strong, even after removal.
My nails are damaged and prone to chipping. Is Xtrem Flash™ suitable for my nails?
Xtrem Flash™ was designed for damaged, soft nails that cause polish to chip too quickly! Occasionally or with every manicure, replace your Green Flash™ Top Coat with the Xtrem Flash™ Top Coat to double the wear time of your manicure, for up to 21 days of wear and shine. And removal stays easy!
My manicure with Xtrem Flash™ lifted on the sides, why?
This can happen if the Top Coat Xtrem Flash™ got onto the cuticles or the side edges during application. When the product touches the skin, it does not adhere properly to the nail and can cause lifting. To avoid this, make sure to push back your cuticles before your manicure, and always leave a slight gap between the polish and your cuticles as well as around the nail contours.
