Reviews from Professionals
"I’ve been using this a lot lately and honestly love how easy it is to work with. It levels really nicely without running. The finish stays super clear and smooth too!"
- Norah L., Mellow Bar Nail Professional
"What I appreciate most is the consistency. It’s not too thin, not too thick, and just really easy to work with. Self-levels well, cures clean, and doesn’t leave that sticky feeling."
Miyuki H., Tokyo Nail Artist
"After testing all three gels, I love how flexible the system is. I can switch between the Comfort Fit Base and 3-in-1 Base depending on the nail, and the wear has been solid with minimal chipping."
- Chris L., NYC Independent Nail Artist
