I have really thin eyebrows, and I want to get false eyebrows for myself, however, I have a sensitive skin, and therefore, I am a bit apprehensive about using them. Moreover, I have thought of buying false eyebrows from MAC but I donât know how to use it. I want to know if it would cause any problem to my real eyelashes at any point of time. Can somebody please advice about its using tips as well? Thanks.
