Good, but not quite navy blue
"It’s a pretty blue, but not what I thought it would be. In person it has a slightly more purply tone to it. The formula was good to work with, not super thin but not thick and goopy"

"I just made another review and I didn’t realize it was another company that I had received an email from From asking how the customer service was. I actually haven’t heard back from you yet. I love love love your nail polish! It’s literally one of my favorite things! I have been discouraged, however with my last few orders. All three of my last orders have been missing product. When they arrive at my door, the packages are open and several items have been missing. I’m wondering if the package isn’t getting closed properly when shipped? It looks like the adhesive is not that good on the envelope."

Our Frequently Asked Questions from our customers and community!
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, colour 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!
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):
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™ colour 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 colour and top coat from another gel/regular nail polish brand will not work.

Bio-sourced ingredients: up to 84%, vegan and non-toxic (for real)!
Lasts up to 12 days: according to a survey, our customers like having the option to remove at home and change colors after 12 days, rather than letting nails grow out for 1 month while waiting to go back to the beautician!
The Green Flash™ formula meets European standards and does not contain any sensitising substances like the methyl acrylate monomers, HEMA, acrylate, titanium or nickel found in the formulas of many traditional gel polishes. It is also certified gluten-free and safe for people with gluten intolerance and celiac disease, as are our Green™, Active™ and nail care ranges. Most customers who are allergic to regular gel polish are not allergic to Green Flash™ polish. However, as allergic reactions are not specifically linked to chemical ingredients, they can sometimes occur with plant-based ingredients. We recommend you speak to a healthcare professional if you are unsure.
The Xtrem Flash™ top coat has been formulated in strict compliance with European cosmetic regulations, among the most demanding in the world. As with any gel, reactions may still occur in individuals who are already sensitised, most often due to poorly cured residue or product coming into contact with the skin. To minimise this risk as much as possible, we support our customers with a precise application protocol: apply thin layers, remove any excess from the cuticles before curing, and cure the thumbs separately to prevent the product from shifting. This guidance ensures a smooth and confident experience when using our top coat.
For more information, see our blog on allergies.
Each lamp can have a different wattage and specific curing time for optimum results.
Our Green Flash polishes have been tested with our lamps to guarantee long, beautiful wear.
Recommended curing times depend on your lamp model:
We have not determined the appropriate curing time for lamps of other wattages, so we cannot guarantee results with these lamps.
It is essential to adhere to the recommended catalysis times to achieve the desired result!
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!
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.
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.
Our Green Flash™ polish is recommended for ages 16+.
Your health is at the heart of our priorities! Although our products are up to 84% bio-sourced, they have not been specifically tested on pregnant or breastfeeding women. As a precaution, we recommend discussing it with your healthcare professional, who will be able to guide you according to your situation
