FAQs

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

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.

Do I have to use a Base Coat?

Our Base Coat protects your nails and helps our Green Flash™ polish to last longer. It will ensure staying power and shine for up to 12 days.

When should I apply my Base Coat?

The Base Coat is the first step in a Green Flash™ manicure. It is applied to bare, prepped nails, i.e. the oil has been already been removed with Green Flash™ Nail Oil Remover or Nail Polish Remover. You then have to cure it under a lamp.

Does the Base Coat care for and protect my nails?

Our new Green Flash™ Vitamin-Enriched Base Coat strengthens and protects your nails under their colour thanks to its patented KeraHCE+ formula that combines hexanal with vitamins C and E. It helps your Green Flash™ polish to adhere for long-lasting, ultra-pigmented colour and a mirror shine for up to 12 days.

Why does Green Flash™ Base Coat never fully dry?

It is normal that our Base Coat does not dry completely the first time you cure it under the lamp! It is designed to only partially dry so that your colour adheres better.

Will Green Flash™ Base Coat work with a gel nail polish from another brand?

Green Flash™ Base Coat has a plant-based formula that is only compatible with Green Flash™ polish.

What’s the difference between Xtrem Flash™ Top Coat and Green Flash™ Top Coat?

Green Flash™ Top Coat is a gentle, naturally derived formula that delivers a glossy natural finish, up to 12 days of wear, and removes in just 1 minute with Green Flash™ acetone-free Remover.
Xtrem Flash™ Top Coat is a gel finish that lasts up to 21 days, with intense, plumped shine. It removes in 10 minutes with Green Flash™ Remover. Xtrem Flash™ is the perfect choice for anyone looking for a long-lasting, professional gel effect without filing or acetone during removal.

Reviews

Très décue

"Je suis déçue par ce produit. J'étais très contente au départ de trouver des vernis qui tiennent et avec une compo clean. Et finalement, en plus de jaunir et ternir les ongles, cette base contient du BHT déjà perturbateur endocrinien, toxique et en plus extrêmement nocif pour l'environnement. Pour une marque''green'' je suis très déçue..."
