I ran before I could walk, and I have suffered for it, I only did enhancements on myself at the time but because I had not had the proper training monomer was getting all over my fingers, they would itch like mad with little blisters skin peeling off I was suffering from over exposure, I still suffer from it now and alway's will, I have since then been properly trained and at least once a year I do course to keep up with growing trends, over exposure is a terrible thing to have I now wear gloves when doing clients nails and when I do my own I have to be extra vigilant, anyone who is not qualified by professional training is exposing clients to this awfull exposure, thought I would just mention this part as no-one else covered it.
