Green™ System, an easy 5-step routine
For a radiant Green™ manicure that lasts, we recommend properly preparing your nails with the advice provided in this article. Then, adopt the Green™ System, a 5-step routine to apply as follows:
- The Degreaser: prepare the nail surface by removing all traces of oils with the Degreaser, for better adhesion and longer tenue of your Green polish.
- The Green Base Coat: apply a layer of Green Base Coat, enriched with vitamins and hexanal, which protects and strengthens the nail and helps fix the color better.
- The Green™ Color: apply your Green™ polish and enjoy an ultra-pigmented color and extreme shine.
- The Top Coat: sensitive to natural UV, the Sunshine Top Coat speeds up drying time, extends the tenue of the polish, and gives it a gel effect.
- The Drying Drops: applied at the end of the manicure, these Drying Drops halve the drying time and deeply nourish the nail contour.

The limits of classic polish
However, polish without a UV lamp has its limits. No matter how carefully you prepare your nails before application and follow the Green™ System to the letter, it will last less long than a semi-permanent polish. A Green™ polish stays flawless for up to 7 days, provided you don’t put your hands through too much wear and tear.
Our tips to extend the tenue of this type of polish:
- Avoid exposing your nails to hot water for too long. Wear gloves when doing the dishes and take showers rather than baths.
- Avoid shocks and abrasive contacts; it’s not the time to start DIY or gardening.
- Keep hydrating and nourishing your nails by regularly applying a few drops of Green Oil.
After more than a week, the resistance of Green™ polish diminishes and it starts to chip. If needed, you can extend its life by touching up the most damaged areas. But ultimately, it’s better to remove your polish with a gentle, acetone-free remover and take care of your natural nails before applying a new polish color.

Prepare your nails well before applying a new Green™ color.
If you’re looking for a long-lasting nail polish, let yourself be tempted by the Green Flash™ experience!
Flash for long-lasting polish
Green Flash™, the 1st LED polish
Green Flash™ is THE next-generation polish that revolutionized the manicure world by offering a safe & clean alternative to classic semi-permanent polish. Like semi-permanent polish, Green Flash™ promises perfect tenue for up to 10 days and a gel-effect shine that we love. It is also applied in several layers of polish that must be cured under a suitable LED lamp. The difference is its vegan formula, free from allergenic molecules (such as methacrylate monomers including HEMA and di-HEMA) and up to 84% biosourced ingredients (cassava, cotton, sugarcane, corn, or wheat). Thanks to this innovation, Green Flash™ removes in 1 minute with a gentle remover, without needing to file, buff, or use an acetone remover that dries out the nail and its surrounding skin. In short, with Green Flash™, you get the pleasure of a beautiful manicure that lasts without risking the health of your hands.

- The Green Flash™ Color: apply your Green Flash™ color in 2 thin layers and cure after each layer under the LED lamp (2 minutes for a Slim 24W lamp, 1 minute for a Premium 36W lamp).
- The Top Coat: apply the Green Flash™ Top Coat (12-day tenue) or the Xtrem Flash™ Top Coat (21-day tenue) then cure under the LED lamp.

2 LED lamps for a Green Flash™ routine that fits you
Manucurist has developed 2 LED lamp models to best meet your needs. Both are equally effective and ensure a quality manicure, provided you respect the recommended drying times. If you exceed the indicated times, your polish may chip.
- The Slim 24W lamp is a foldable lamp that’s easy to travel with. It plugs in via USB or with a 5V/2A adapter. With this model, expect 2 minutes drying for the Base Coat, 2 minutes for each polish layer, and 3 minutes for the Top Coat. In total, your manicure takes about 30 minutes.
- The Premium 36W lamp is also foldable but slightly larger and more powerful than the Slim lamp, allowing faster curing, ideal for those in a hurry. With this model, expect 1 minute drying for the Base Coat, 1 minute for each color layer, and 2 minutes for the Top Coat. In total, your manicure takes about 20 minutes.
Manucurist LED lamps go everywhere with you for a Green Flash™ manicure wherever and whenever you want!
In summary, Green™ polish is an excellent option for those who like having a wide color choice and are beginners with nail polish. As for Green Flash™, it’s the ideal polish for those who want long tenue without wasting time or damaging their nails.
Frequently Asked Questions
Can you apply semi-permanent polish without a lamp?
It is not possible to apply semi-permanent polish without a UV or LED lamp. Indeed, to harden, this type of polish must be exposed to UV rays to trigger a polymerization process, essential to ensure the polish adheres well to the nail and lasts several weeks without chipping. If you want to avoid using a UV or LED lamp, you can opt for classic polishes that air-dry. They offer equivalent shine and gel effect but are less resistant and last less long.
Are UV lamps dangerous for health?
A recent study by the Academy of Medicine warned about the risks related to exposure to UV lamps used for drying semi-permanent polishes. This study noted cancer risks with frequent use, with UV lamps over 48W power and exposure times of 20 to 40 minutes per day. With a maximum power of 36W, exposure times of 5 to 9 minutes per manicure, and clearly displayed usage precautions, Manucurist LED lamps can be used safely. If you have sensitive skin, don’t hesitate to follow the Academy of Medicine’s recommendations by applying sunscreen on your hands 20 minutes before applying semi-permanent polish.
