24 hours. I think that was my previous record for maintaining shiny, newly polished nails. I tried Gelish, Shellac and OPI gel manicures and while they did last longer, I worried about the UV exposure (who needs scary, wrinkled hands!) Enter Signature Nail Systems. My manicurist talked me into trying the powdered colors and now I'm 100% hooked. My last "set" lasted 3 weeks and soak-off removal didn't leave them damaged or shabby! Hooray! Probably my most favorite beauty find of the year (so far...) Try "Puppies Breath" for a pretty nude-pink. Click for SNS salon finder.
