Perfecting base that hides ridges and smooths uneven nails
A ridge-filling nail primer that doubles as a Biotin and Florium-fortified base coat. One coat instantly levels out unevenness to create a smooth canvas; a second layer further fills in deeper-set lines to conceal the look of bumps. Wear this treatment as a perfected, natural, satin-finish manicure, or use it as a durable base coat that prevents your favorite polish from chipping and peeling. Either way, your nails get immediate and long-term benefits with every use: why mind the gaps when there’s a solution for them?

I have prominent ridges. I have tried many ridge fillers over the years and most of them made my ridges even more visible or were too gummy and thick, and the nail polish never wanted to stick to them. This one is different. It really helps my ridges look less visible, without a thick build up, and nail polish adheres to it very nicely. In the photo here, I only used one coat of filler under two coats of nail polish. If the polish is more sheer, I like to use two thin coats of the filler.
I recently had acrylic nails removed after having them for only 10 days. My nails are ruined. Lumpy, bumpy a real mess just one coat and my nails looks great. I can use this until my new nails grow out.
Love the product and it works.
This might just be my holy grail base coat. It holds like nothing else I’ve tried. I’ve used this on 4 manicures now and for the most part it helps the polish lasts a solid week and a half before starting to noticeably crack or chip (the picture is from 10 days after painting). It’s also very good at filling ridges. One of my fingers has very large ridges that wreak havoc on sheer polish. Another ridge filling base coat took about 6 coats to fully smooth them out—this took 3 to get almost the same coverage. I highly recommend giving this a try.

I use this after using the gel strong nail hardener. It fills in the ridges on my thumb that I acquired years ago by closing the car door on my thumb. The Fortifying Ridge Filler also fills in the ridges from getting my nails done at the salon. I like the opaque white color because it brightens the part of my nails that have turned yellow from the tool the nail tech used to remove the dip nails. I also like the way it makes the surface of my nails smooth and not sticky.
