From what I understand you DO NOT need to have a level 3 beauty to study laser just the level 4 core of knowledge and high capital.
It does depend on laser though as tattoo removal laser,hair ,scarring e.t.c
For hair removal it is stricter than say tattoo as a therapist should also be trained in the use of the laser equipment for your treatment. The minimum requirements for the person in charge (owner) are that they hold a current Registration on Healthcare certificate, have training on the laser equipment, and have attended a laser safety study day.
The minimum training they should have received on the laser equipment should cover the hazards of using a particular machine, risk assessments, a certificate of competency and proof of their training. It is also strongly advised that they have training in basic CPR and first aid, and general health and safety awareness.
it is also required by law that practitioners who carry out laser hair removal procedures are insured. There are two different types of insurance needed: public liability/employer liability and professional indemnity insurance. They must also have current membership of an appropriate professional organisation.
