What’s the difference between the new Vitaminized Base Coat Green Flash™ and the original Base Coat Green Flash™?

Thanks to an innovative molecular complex combining Hexanal, Vitamin C, and Vitamin E, the new Vitaminized Base Coat protects and fortify nails under color. The original Base Coat also provided protection but did not offer strengthening benefits.

How long does it take to cure my Green Flash™ polish?

The curing time depends on your lamp:

36W lamp (Pro Lamp): 1 minute for the base coat, 1 minute for each coat of color, 2 minutes for the top coat.
24W lamp (Slim Lamp): 2 minutes for the base coat, 2 minutes for each coat of color, 3 minutes for the top coat.

These times have already been programmed into your Manucurist lamp and it is important that you don't exceed them! Each coat should still be very slightly tacky at the end of each step so it adheres to the next.

I'm having trouble removing my Green Flash™ polish - is this normal?

Absolutely not!

Soak 10 small cotton pads (the size of your nails) in gentle, acetone-free nail polish remover, like our Green Flash™ Nail Polish Remover. Press a cotton pad onto each nail. Use our nail clips to hold them in place. Each nail should be completely covered by its soaked pad. Wait for 1-2 minutes without touching them. Remove them one by one and the nail polish should come off with them!

If there is still some base coat left, you can repeat the process for a few seconds.

My polish seems too thick - is this normal?

The thickness will depend on the amount of pigmentation in the polish.
If you prefer a more liquid consistency, our plant-based thinner will be your best friend!

Is the Green™ range compatible with the Green Flash™ range? And with products from other brands?

Unfortunately not, each formula is unique and made from different ingredients. Our Green Flash™ products should only be used with products from the same range to ensure the best results.

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.

Reviews

The Green Flash Vitaminized Base

"The Green Flash Vitaminized Base Coat is an excellent first step in a healthier gel manicure routine that delivers strong adhesion and nail protection while still being gentle and clean. It’s designed specifically to work with Green Flash™ polishes (so the colour and top coats adhere beautifully), and it combines strengthening and protective benefits thanks to its patented technology that includes hexanal for nail repair plus vitamins C and E for resilience and durability — which many users report result in noticeably harder, healthier‑feeling nails after a few manicures. What sets this base coat apart is its nail‑friendly formula: it’s high in plant‑based ingredients, vegan, and free from harsh chemicals often found in traditional gel bases. Many reviewers appreciate how it creates a smooth, glossy base that helps colour polish lay down evenly and increases the wear time of the mani. Some also note that it helps reduce breakage and peeling over time. "

Great base coat

"Really great base coat nail polish and works very well with the gel polishes"

— Michelle (4/5)

Works great.

"The product is very thin and cures quickly. Also does not damage my nails upon removal."

— Maria B. (4/5)

Very disappointed. Bottles of varnish

"Very disappointed. Bottles of varnish all very thick and glupey, couldn't get a super thin layer on a result and it just wouldn't dry under the lamp. I've gone back to my gel polish which is far easier to use and dry. I will not be purchasing anything again. I really wanted to like this, but it's not for me."

— Tara T. (1/5)

Sono prodotti fantastici, anche l’assistenza

"Sono prodotti fantastici, anche l’assistenza devo dire che è stata ottima, mi hanno immediatamente risolto un problema"

— Rosalba C. (5/5)

All products were good. My

"All products were good. My manicurist has left and I need more product. , But I need to find another girl!…do you know anyone in London SW3 2LE?"

— Vanessa B. (5/5)

Pessimo

"Personalmente riscontro che lo smalto non si asciughi bene nonostante da anni usi smalti semipermanenti, e sembra esattamente identico agli smalti normali (non semipermanenti). Inoltre non esiste rimborso né reso se si riscontrassero problematiche come le mie. Pessimo."

— Vittoria (1/5)

I use this base coat

"I use this base coat for pedicures. The pedicure last for weeks until I take it off. I love the fact you can put foot wear straight on after. I cheat with the travel lamp as I put both feet under at the same time making it even quicker"

— Deborah G. (5/5)

I got the whole set

"I got the whole set base coat, colours and top coat and LED Lamp. To fully cure base coat I do 2-3,min. The base coat feels sticky if only used for 1min cure time. The colours I do 3min and top coat 2min. So far my feet has lasted nearly 2 weeks and now I am testing it on my hands. The only downside is the lamp I feel like is bit too hot."
