A formal presentation should be given, explaining what your training and experience is. I suggest that you organize a portfolio with all the available information and photographs of the procedures you have done previously, choosing cases representative of each procedure that you perform. This will make your consultation easier and give your client the confidence they need.
Once the initial approximation is done, the corresponding forms should be filled out, asking for all identification data, medical history, allergies, ESPECIALLY SOME OF THE COMPONENTS OF THE PIGMENTS, anesthetics or healing cream that you use, etc. in order to identify any condition that contraindicates the procedure. It is advisable to offer an allergy test, which if he or she accepts it, must be done 15 days prior to the procedure and paid by the client as something additional to the procedure itself (I will explain in detail in a later blog).
Explain to your client what the procedure is, what the risks are and what kind of materials you use. I advise you also take the time to explain the whole process of healing and when the client will see the final result.
