Remember that black, blue or green used for eyeliner are very likely to migrate creating a bruised look around the eyes. There are now many more law suits for permanent make up by clients who are not happy. Asking them to sign a "disclaimer" does not work. YOU are the professional NOT the client! It is your PROFESSIONAL RESPONSIBILITY to know the correct shape and colour required for your clients. REMEMBER :- A DISCLAIMER IS NOT VALID IN THE LAW COURTS.
