Susan Feghali, manager of Splashclinic in Penrith, said at least two people a week come to her for help for botched procedures elsewhere.

``People come to us because the treatment hasn't worked properly or because they have more serious problems such as burns,'' she said.

The warning follows calls earlier this year from state MP Michael Richardson (Castle Hill, Liberal) for state regulation of the use of IPL and laser machines.

At present, only Western Australia and Tasmania have laws which regulate the industry.

Queensland regulates lasers but not IPL.

Ms Feghali said the industry should be better regulated so that training is compulsory and that clients need to be more responsible about their own treatment.

``Untrained therapists do not understand the settings of the lasers, nor how skin types may respond,'' she said.

``We try to educate people on what the risks are and what they need to do afterwards. It is not something to be taken lightly.

``In many cases the treatment is fine but the client doesn't always follow instructions or may lie in the sun straight after treatment.''

Ms Fegahali said anyone seeking laser therapy should first consult a therapist to assess their suitability.
