"Super produit qui permet un séchage rapide en laissant le contour de l'ongle hydraté et permet d’atténuer l’odeur des vernis à ongles"
— Anne G. (5/5)
"I've been using this again for the last couple of months. I'm sure it's helping but my nails are so weak and damaged from nail bars I can't expect miracles and realised my nails probably needs to grow out Atleast 3-4mm to show the healthier, stronger nail. I've been using polygel wraps, but these are unsuccessful due to the bendyness of my nails so I am swapping to The Manacurist Green flash LED range to treat my nails and protect them. I will give my nails a weekly treatment of SOS and keratin and night masque treatment before reapplying the polish using the vitamin base. Hoping in 3-6m9ntus my nails show distinct improvement. I trust the manacurist range and have used it on and off over the last year."

"La base semble efficace : en 1 utilisation, j’ai trouvé que mes ongles étaient plus solides, durcis. Je parle de l’état de mes ongles après avoir enlevé le vernis soin SOS au bout d’une semaine."
— Camille B. (5/5)
"This is one of those products you didn't know you needed until you try it. It took me about 3-4 uses of Base S. O. S. and my nails are now visibly healthier and they feel significantly more strong/firm. I have been able to actually grow them out to a few millimeters with this miracle product. Base S. O. S. I use both as a base under the green polish and by itself, about twice every 10 days. I will continue to use as long as it exists!"

"Mi trovo molto bene con questa base. In effetti rinforza le unghie e mi sta aiutando molto a farle ricrescere sane dopo una manicure sbagliata."

"Bien j’achète tout vos produits mais j’ai du racheter un top coat alors que le mien etait que a moitié car il s’épaissit et difficile a mettre"
— Carine J. (5/5)
"Ottimo si stende facilmente, dona lucentezza all'unghia e la rende più resistente."
— Palmina P. (5/5)
"I love this basecoat! It leaves a gorgeous shine and it stays on for so long. Normally anything peels off within days for me but this stays on quite well (ofc it helps that it's transparent). I also feel like my nails feel stronger and healthier from the first day that I've been using it. It's also great in combination with nailpolish, but I do notice some chipping then. But it's defenitely my go-to when I want healthy shiny natural looking nails!"
— Eva S. (5/5)
"Didn’t expect this result! I had heard that a glass buffer is ideal for peeling nails, but I didn’t expect such a result! I used it, applied a layer of Base SOS, and they look better than ever."

Our Frequently Asked Questions from our customers and community!
Treatment base coats can be used as a base coat as part of your Green™ manicure.
However, they cannot be used instead of a Green Flash™ base coat, which needs to dry under the lamp.
A single coat is enough.
When using a treatment base coat, there's no need to remove the previous coat.
For maximum staying power, we recommend that you only use Green Flash™ Base Coat.
All treatment bases remove like our polishes, with our Dissolving Oil or our Green Flash™ remover.
Every nail type is different! Complete our online nail analysis to help you select the most suitable nail care products.
We can then offer you a nail care programme tailored to your needs!
The S.O.S Base Coat is designed for brittle nails weakened by external aggressors, e.g. frequent use of gel nail polish, excessive drilling or filing, overexposure to chemicals, etc. The Force Base Coat is for soft nails that tend to flex or bend easily.

Our nail care formulas are green and clean: they are up to 99% plant-based, i.e. made from biomass ingredients like aloe vera, lemon, ginseng, pomegranate and grape. However, women should avoid all types of nail polish when they are pregnant or breastfeeding. We recommend you speak to a healthcare professional if you are unsure.
Our nail care formulas meet European standards and do not contain any sensitising substances. They are also certified gluten-free and safe for people with gluten intolerance or celiac disease, as are our Green Flash™, Green™ and Active™ ranges. Most customers who are allergic to regular nail care products are not allergic to the Manucurist nail care range. 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.
For more information, see our blog on allergies.
