I can't wait to give this a try! :-) Since I love all of the other Le Mini Macaron products I have purchased, I am confident that I'll love this as well! :-)

Wonderful Product

I knew I would not be disappointed trying this product. I’ve been using le mini macaron products for years now I’m adding super nail hardener to my collection. I love the fact that all products I’ve used from le mini macaron have a large percentage of natural ingredients. The best nail products for my money. Thank you

This is wonderful and I'm happy to know you keep enjoying our products, Laura! Thank you for this comment ❤️

Love for the in between manis

I have weak nails and I’m hesitant to wear gel all the time; add the food industry job and my hands take a beating. This little rockstar helps keep my nails looking good regardless of what they need to do.

Love It!

I’m on my second bottle! The first bottle was a gift from my daughter-in-law. Finally my nails are growing without chipping or peeling!


I've only used it once, but seems good.
