Great two in one product

I love that this product works as both a base coat and a hardener. It applies easily and dries fairly fast. Can be used alone or layered under other polishes.

Best hardener ever

I noticed immediately the stronger feel to my nails. They are pretty short from growing out poly gel and I have been treating the cuticles with nail food (so I don’t know how much that has contributed to my healthier nails) but this product made an obvious feel stronger feel and my nails are actually growing out. With the use of the ridge filler, polish and top coat, my manicure has lasted an entire week, all nails. A miracle for me since my manicures usually last two days. Good product.

Amazing base for color polish!

Firm foundation is a great product to use alone to strengthen or nails or works amazingly as a base for color polish.

I have brittle nails so I have to use a treatment as a base rather than a normal base. Before firm foundation got released I would use first aid kiss and that works great to strengthen my nails but was not so great as a base for color polish. I used firm foundation under my color polish and you can’t even tell! The color went on perfect. I highly recommend firm foundation as a base.
