I can see in this video: http://www.youtube.com/watch?v=wFt7gZJPKvk that she is receiving severals shots in the same skin-area. Is better to receive a lot of shots in the same skin-area? Mote shots in the same part of the skin = better?
Only one shot is enough? or always are needed more shots in the same area? how many shots in the same area for better results?
thanx!!!
