Manucurist unveils semi-permanent effect top coat with mirror shine and 21-day wear

In April 2026, Manucurist strikes hard with a novelty that could well change your habits. Top Coat Gel Xtrem Flash™ arrives on the market with a bold promise: to offer a domed finish and mirror-like shine worthy of semi-permanent, without its usual drawbacks.

You know the dilemma. On the one hand, the impeccable rendering of gel nail polish at the salon. On the other, aggressive application, acetone and brittle nails. This new formula from the French brand attempts to reconcile the two camps.

A professional gel effect for the home

In recent years, the Green Flash™ range has established itself as a gentler alternative to classic semi-permanent. Yet some users found the rendering slightly below theprofessional gel effect. With this new top coat, the brand takes things a step further.

Here, everything is designed to reproduce this addictive result. A domed effect that sheathes the nail, an almost lacquered mirror shine, and that impression of a freshly done manicure that lasts. In tests, 100% of users observed intense shine.

“The product that was missing to find that uncompromising effect.”

What’s more, 80% of testers found nails to be tough as nails. Nails look cleaner, smoother and plumper. The glossy finish is reminiscent of salon manicures.

Long-lasting hold without sacrificing nail health

The great strength of this top coat lies in its durability. While the range’s classic top coat lasts around 10 to 12 days, this Xtrem version lasts up to 21 days. A manicure that stays clean, shiny and smooth for much longer, without touch-ups.

Its gel texture acts like a protective film. It sheathes the nail while providing that much-appreciated domed, ultra-glossy finish. So no need to choose between beauty and nail preservation.

• Domed finish and mirror shine
• Holds for up to 21 days
• Removal in 10 minutes without sanding
• Compatible with the Green Flash™ range
• Price: €25

How to apply this new top coat

Top Coat Gel Xtrem Flash™ is used as the final step in the Green Flash™ routine. After base and color, a single coat is enough to seal the manicure. The gel effect appears immediately.

Please note: this product works exclusively with Manucurist’s Green Flash™ polishes. The formulation has been thought out for this precise compatibility. Thus, hold and shine remain optimal.

This technical constraint guarantees the promised result. On the other hand, those who already own the Green Flash™ range will appreciate this natural evolution of their routine.

Quick and easy application

No need to be a nail art expert. The application is identical to that of a classic nail polish. A thin, even coat is all it takes to achieve the desired effect.

The brush facilitates precise application right up to the nail edge. In this way, the domed finish appears uniform on every finger. The mirror-like shine is immediately apparent.

Gentle application that preserves nails

This is often the weak point of traditional semi-permanent. Sanding and pure acetone damage the nail surface with each application. Manucurist offers a different approach.

To remove this top coat, the usual Green Flash™ method is all you need. In just 10 minutes, the varnish can be removed just like a classic varnish. No file, no aggressive gestures.

From now on, nail removal no longer rhymes with brittle nails. Nails remain clean, residue-free and, above all, much less damaged than after conventional semi-permanent.

This respect for the natural nail is part of the brand’s overall philosophy. From the outset, Manucurist has focused on more respectful formulas. This new product extends this commitment with a professional finish that’s accessible at home.
