Essie Ridge Filling Base Coat
Ridge filling base coat: Give nails with ridges or discoloration a smooth, even base for color application. Leaves nails looking more youthful and smoother, as if resurfaced.
I love this ridge-filling basecoat. It self-levels, evens out imperfections and ridges, makes discoloration less apparent, and is overall a great foundation for nail polish. I even wear it often by itself. And I love that I can buy it from Sleek Nail for such an affordable price. Definitely worth more, to me anyway, because it's a great all-purpose basecoat that doesn't peel or chip easily, but having it for this price at Sleek Nail is so nice. I do my own acrylics (not a nail tech, just an amateur), and I prefer using a hand file instead of buying and using a drill, so sometimes my filing of the acrylic after it hardens isn't as perfect as it would be with a drill by a professional, and this basecoat makes it look like I was perfect with my acrylic application. If you're looking for a great, easy-to-apply basecoat that makes your nails look gorgeous even on its own, try this one.
My nails had developed some ridges that ruined the look of a manicure. Smoothing then made them too thin, leading to breakage. Found this and have been a fan for several years now.
