O.S. Base Coat Nail Strengthener Gel Base Coat | Repairing nail treatment with vitamins C & B5 for very damaged nails. Vegan, up to 78% plant-based, Made in France, 15 ml

I have multiple nail issues and had used a plethora of expensive varnish type nail strengtheners. There are only two that really worked; Nailtiques Formula 2 and Manicurist SOS base coat. They are both good quality and effective, though they work in a different way. The primary difference is their key active ingredients: Nailtiques Formula 2 is a protein-based treatment that bonds nail layers with hydrolyzed keratin and gelatin, while Manicurist SOS Base is a vitamin- and AHA-enriched formula that works to moisturise and gently exfoliate the nail surface. Both are designed to address damaged and weak nails. The choice between the two depends on the specific nail concern. Nailtiques Formula 2 is best for nails that are fundamentally soft, peeling, or splitting, providing a strong protein structure to bond the nail layers. Manicurist SOS Base is ideal for brittle, very damaged nails that require intensive vitamin enrichment and hydration to recover from external stressors like harsh chemicals or frequent gel manicures. I found both products helped my nail health and appearance, producing fairly similar visual effects. As mentioned the SOS base coat is a varnish type of a strengthener and it can be used on its own or as a base coat under a nail polish. Used on its own, the product provides excellent protection for the nails. The SOS Base coat is colourless and, to me, it smells just like any other nail varnish. It is supposed to be applied twice weekly, however I apply it every other day. Once applied, it dries quickly, does not chip away and lasts for at least a week. Always apply one coat only; the first time you apply it do not do two coats, as it will take some time for the varnish to fully dry, and it could smudge. One coat per application is enough. Post application, the nails feel smooth and look nice and shiny. The appearance improves with additional applications which further cover up any visible imperfections such as nail ridges. After removing it, the nails feel stronger and look brighter and smoother. I really like it and cannot think of anything, even slightly, negative to point out with regards to this base coat. When it comes to results, the 2 subtle differences between the Nailtiques and Manicurist that I noticed, is that Manicurist SOS helped heal a stubborn, long term vertical split, whilst the Nailtique appears to have resulted in a slightly faster nail growth. Compared to Nailtiques, Manicurist SOS Base coat is significantly cheaper, and it lasts longer, since it is recommended for use only twice a week, whilst the Nailtiques Formula 2 is supposed to be used daily. With this in mind, in addition to what it actually does I'd say that Manicurist SOS Base nail strengthener is good value for money, and have no hesitation in recommending it.

Thank goodness I was recommended this product. It has saved my nails. I use it alone and as a base coat. It's been a month since I began using it and I am filing my nails back now instead of them breaking and peeling. It's so much more than a base coat. I will be buying some of their polish and top coat next now it has my nails back to health and looking lush.

Can be used on its own or as base for a colorful manicure. This is the only brand I know that does not damage nails. The polish prevents nail from chipping. Worth the price!

Very good but alas nothing seems to help my very thin splitting nails

My nails are thin after too much gel. This has really helped strengthen again and it’s a lovely natural but classy colour. Dries quickly

I've been using his for a while now. I tend to apply 2 coats and it is starts peeling off, then apply again. It lasts about a week, then I remove it and start again with 2 coats. It is clear and shiny. Very nice. Better than other brands I've tried in the past. I also use the green flash polish, so this is a nice break from it ever now and again. My nails break a lot and this is helping.

It does not adhere to the nails; it peels off within a day, despite having a strong smell that is hard to tolerate with the window closed.

This is a good, if somewhat pricey product. However, you get what you pay for and it's worth it for strong nails. Mine are a nightmare after too many gel nail applications/removals. It does the job of making your nails stronger. I use two coats under nail varnish. It's easy to apply, nice texture, dries quite quickly. Very pleased and would recommend.

Produit très satisfaisant ! Améliore l’état des ongles et leur apporte une jolie brillance.

Der beste Nagelhärter, den ich bislang hatte.

Llevo usando Manucurist Green base S.O.S. apenas una semana y ya, desde la primera aplicación, he notado mejoría en la debilidad de mis uñas. Espero que con la regularidad del uso y más tiempo, sus efectos sean aún más evidentes. Es fácil de aplicar, seca rápido y deja un brillo natural en la uña. El envío fue perfecto y puntual.

My Amazon purchase history says I bought this in February. It is now May and I use this stuff at least once every two weeks. I am not even 1/4 of the way through the bottle. It is worth your money, it will last you a while (probably). Here are the things it has done for me: 1: Strengthened my papery nails. They are now hard and do not break anywhere near as easily. 2: Made my nails grow faster. 3: Made my manicures last longer. That is all it really needs to do for me; it is nail polish, not insulin. Things it did not do: 1. Smooth any pitting or ridging that I have on some of my nails. I think you can only fix that with vitamins. Will I buy this again? Yes. This will be a permanent item. I need it now.
