FAQs

Les questions les plus fréquemment posées par nos utilisatrices et notre communauté !

I've never used gel polish before - is it tricky?

Anyone can apply Green Flash™, including complete beginners!

If you know how to use regular nail polish you can use Green Flash™: you apply the base coat, color and top coat in exactly the same way. The only difference is that you cure your nails under the lamp!

If you know how to use gel polish, there are a few points to note. Applying Green Flash™ is more like applying regular nail polish: there's no need to remove oil first and the polish is not buildable like gel polish, so you need to get it right from the start.

We recommend that you treat it like regular nail polish that has to be dried under a lamp!

Is Green Flash™ compatible with other brands?

Unfortunately not, each formula is unique and made from different ingredients. Our Green Flash™ products should always be used with other Green Flash™ products to ensure the best results. You will need (at least):

  • One Green Flash™ base coat
  • One Green Flash™ color
  • One Green Flash™ top coat
  • An LED lamp with an output of at least 24W

For effective removal, we highly recommend using Green Flash™ plant-based Nail Polish Remover and the accompanying nail clips.

Points to note:
Using a Green Flash™ color with a base coat and top coat from another gel/regular nail polish brand will not work.
Using a Green Flash™ base coat with a color and top coat from another gel/regular nail polish brand will not work.

What is the difference between a traditional gel polish and Green Flash™?

The "peel-off" removal: it can be removed at home without acetone, rubbing or filing it off!

It dries instantly: using an LED lamp with an output of at least 24W at a frequency that is less harmful to nails than UV lamps!

Up to 84% plant-based ingredients that are also vegan and non-toxic (really)!

Lasts up to 12 days: according to a survey, our customers like having the option of removing their polish at home and changing their color after 12 days, rather than letting their nails grow for a month and then returning to the salon!

What is the difference between a regular nail polish and Green Flash™?

The "peel-off" removal: it can be removed at home without acetone, rubbing or filing it off!

Dries instantly under an LED lamp: no more smears while it dries!

Up to 84% plant-based ingredients that are also vegan and non-toxic (really)!

Staying power for 12 days!

Can using Green Flash™ cause allergies?

Green Flash™ meets European standards and does not contain any sensitising substances like the monomers and methyl acrylate found in many traditional gel polishes. Many customers have testified that they have been able to use our products safely, even if they were allergic to other types of gel polish. However, allergic reactions are not specifically related to chemical ingredients, so we cannot guarantee that you won't have a reaction to another ingredient, even a natural one. If this does happen, please feel free to contact us 🌸

You'll find more information in our blog about allergies.

How old do you have to be to use Green Flash™ gel polish?

Our Green Flash™ polish is recommended for ages 16+.

Can I use a Green™ treatment base coat under a Green Flash™ polish?

Unfortunately not, our Green™ treatment base coats are only compatible with products from our Green™ range. You have to use a Green Flash™ base coat for a Green Flash™ manicure. But you can apply a treatment base coat between Green Flash™ manicures to give your nails a little extra TLC!

How can I stop brush marks from appearing in my Green Flash™ polish?

To stop brush marks from appearing in your Green Flash™ polish, you need to apply it in very thin coats using no more than 3 brushstrokes! To get the right amount of product on your brush, scrape the brush stick against the inside neck of the bottle to remove any excess.
Then wipe it from one side of the brush. You should be left with a small drop on the tip of the brush! Use one drop of polish for each finger.

How can I give my Green Flash™ manicure a shine boost after a few days?

If you are wearing Green Flash™ polish, you can apply a coat of our Color Refresher on top of it after a few days. You don't need to cure it, as it air-dries.

How long does gel polish last and how can I make it last longer?

Under normal conditions, a Green Flash™ manicure lasts up to 21 days with Xtrem Flash™ Top Coat, depending on your nail prep and daily activities (water exposure, cleaning, sports, manual work…). If your polish lifts too quickly, it’s usually due to one of the following: application on cuticles or skin (causes lifting at the edges) insufficient nail cleansing layers applied too thick in complete curing or an unsuitable LED lamp Best practices to maximize wear: properly cleanse the nail before application apply thin, even layers avoid getting polish on the skin limit impact and wear gloves for household tasks (especially during the first 24 hours) limit impact and wear gloves for household tasks (especially during the first 24 hours)

How do I remove my gel polish without damaging my nails?

With Green Flash™, removal is quick, easy and gentle on your nails.Soak a cotton pad with Green Flash™ gentle remover, place it on the nail using a removal clip, and leave on for a few minutes.The polish will lift off naturally. If needed, gently remove any residue with a wooden stick.No need to rub, file or peel: the formula is designed for easy at-home removal.Finish with a cuticle oil to nourish and enhance your nails.Tip: highly pigmented shades may require a slightly longer removal time.

How do I apply my gel polish at home?

For a clean, glossy, long-lasting result, it all comes down to proper nail prep and thin layers.

Prep your nails: file to your desired shape, gently push back cuticles, lightly buff the surface, then cleanse.

Apply a thin layer of Green Flash™ Base Coat and cure under a LED lamp.

Apply your powder pink color in 1 to 2 thin coats (2 thin coats give a more even finish), curing between each layer.

Finish with Green Flash™ Top Coat for up to 12 days of wear, or Xtrem Flash™ Top Coat for up to 21 days and a plump gel-like shine. Cure, then apply cuticle oil.

Tip: remove any excess polish before curing for perfectly clean edges.

"I have never done an at home gel manicure set. This is so easy and so pretty. I type all day long and usually even gel will chip. I’m only a few days in, but I absolutely love it. I didn’t really like how the first color I tried was turning out. I decided to switch colors. I couldn’t believe how unbelievably easy this gel was to remove."
