How many laser-shots in the same area are needed?

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!!!

It’s not necessary to hit the same area more than once, but overlapping should be done to avoid patchiness.

overlapping = more risk to the skin? or burns?

thanx!

pd: im going to use laser in my beard so do you reccomend me to talk with the doctor and tell him to shot in the same area a lot of times to avoid patchiness??

Overlapping is standard procedure to avoid missing spots. Some spot sizes are round, for example, making it a bit difficult to cover every inch of the body area without overlapping.

I recommend you ask to overlap by a bit so that every inch of the area is covered.
