Facial extraction and Isotretinoin

Patient: I am currently taking isotretinoin for my severe acne problem. I wanted to ask whether if it is okay for me to do facial (with blackheads and pimples extraction) at those beauty salons? I found somewhere on the Net that one should avoid any activities which can lead to scarring if one is taking the medication. Kindly clarify me regarding this matter.Yours sincerely,Monica.
