Hi i'm using brisa and having a problem with lifting at the sides were the tip is attached but no lifting around the cuticle so i'm sure its not my prep. i really can't figure out why? I use the clear tips and am wondering if the opaque tips would be better as i feel the clear tips are thinner. could it be the application is too thin but then wouldn't they crack? I'm doing three layers. one last question which i'm confused about is the primer do you apply it only on the natural nail plate or do you also go over the tip? Please if anyone can help i would really appreciate it!!! Thanks
