Good evening, I am newly qualified nail technician and beauty therapist. I am REALLY struggling with my uv gel application. As I'm applying it, it keeps running. I have tried a couple of different brands, (NSI, purity pink by pure nails) they are both builder heels, with no improvement. I've tried not putting too much on and building it in layers but it's still running, I've tried flash curing it, still runs. If anyone can recommend a thick consistency gel? Can ANYONE HELP PLEASE PLEASE, thank you.
