Good lord I need to move to the USA and get rich and famous for not being a laser butcher.
The pain, the bruising, the blisters and the scars are caused by people not understanding the process and misusing the equipment.
I never let a client leave with blisters, rarely get even small bruises, have never left a client with scared skin and get really good removal results.
Its time to do some learning people.
If you are offering laser and feel you may be causing pain or damage beyond whats necesary drop me a PM I will be happy to chat.
