Dreaming of a shiny, long-lasting manicure that’s safe for your nails? DIY semi-permanent nail polish kits have transformed the beauty routine of nail lovers. No more trips back and forth to the salon: now you can enjoy a semi-permanent manicure at home, in total comfort. But how do you find the right semi-permanent nail polish kit ? And why have so many of you made the Green Flash™ kit an absolute must-have? We’ll explain it all.
Key takeaways:
- A good gel polish kit stands out for its bio-sourced, vegan polish formula, delivering shine, durability and long-lasting wear.
- A good kit should include everything you need: a Base Coat, a Top Coat, one or more shades, an LED/UV lamp and removal supplies.
- It should be easy to use at home: smooth, intuitive application, quick curing under the lamp and a professional-looking manicure.
- A good kit should offer a gentle removal method, without an electric nail file or acetone, that protects the natural nail.
Our criteria for choosing the best kit
A good semi-permanent nail polish kit is more than just a pretty box: it’s a complete, thoughtfully designed set that combines performance, safety and enjoyment. Here are the 3 things to look for:
✅ A high-performing, bio-sourced formula
To meet the market’s new expectations, next-generation semi-permanent polishes need to be:
- Bio-sourced: this means replacing synthetic petrochemical ingredients with plant-derived, renewable alternatives wherever possible.
- Vegan : the formula must contain no animal-derived ingredients.
All without compromising on shine or wear time. Because bio-sourced polish can be ultra-glamorous too!
✅ A complete, customisable kit
A great semi-permanent kit should contain all the essentials for easy application and gentle removal:
- A base coat, a top coat and one or more polish colours.
- A UV or LED lamp to cure the polish effectively.
- A gentle remover and a set of removal clips.
- As a bonus, everything you need for thorough nail prep: a file, cuticle softener, cuticle pusher, correction pen… the little extras that take your manicure to the next level.
✅ Easy application, a pro-like result
The number one goal of a semi-permanent nail polish kit: to help you give yourself a manicure at home that looks great, even if you’re not a pro. So it should deliver:
- Smooth, intuitive application.
- Quick drying under a UV or LED lamp.
- A glossy, even finish.
- Long-lasting wear without chipping.

✅ Gentle removal, without damaging the natural nail
A good gel polish kit supports you from application through to removal and should ideally ensure gentle removal that respects the nail. Forget the nail drill and acetone—opt instead for:
- A gentle, acetone-free remover that lifts the polish off in one piece and hydrates the nail, thanks to a formula enriched with castor oil, for example.
- A set of removal clips to hold the remover-soaked cotton against the polish and ensure it peels off.
The result: your natural nails are intact, clean and hydrated. It’s the perfect time to give them a little care before your next manicure.
Green Flash™ vs other kits: what’s the difference?
Polish formula, nail prep, lamp type, colour choice, removal method… At first glance, semi-permanent nail kits can look much the same. But from the polish formula to how you remove it, the differences are real. With the Green Flash™ kit, Manucurist has created an all-in-one manicure solution that offers an alternative to traditional semi-permanent polish, combining performance, convenience, the joy of colour and nail care. So what really sets them apart? Let’s compare.
Since its launch in 2019, the Green Flash™ kit has kept evolving with new innovations:
- The Green Flash™ Vitamin-Enriched Base Coat, introduced in 2025, uses its KeraHCE+ technology to strengthen the nail beneath the colour and ensure flawless wear for up to 12 days.
- The Xtrem Flash™ Top Coat, launched in 2026, guarantees long-lasting wear for up to 21 days, with a plumped effect and extreme shine.
