if you want to do your own gel nails [SEP] you will need a nail gel lamp to cure the gel from my experience with different lamps leave your nails in the curing lamp for the maximum time this is quite handy and easy to use follow all instructions and you should get great results hint when you go to start your nails put a coat of elmers glue around your skin around the nail and it will keep the gel base and top coat from sticking to your skin
