SNS is a powder technique instead of gel or acrylic. It is strong like acrylic and soft like gel, but it is your natural nail shape and length. There is no light needed and it dries super fast. I highly recommend it to everyone.
I'm loving SNS nails, have had mine on for about 5 weeks and have only had to paint twice and a bit of a file. Really good way to save money and look after your nails without too much effort and they don't break!
