I am a working woman and like to cosmetic tattoo eyebrows. As I have very thin eyebrows I donât like using eye liner and thatâs why I always feel my make up incomplete. One day I went to a store and there I saw cosmetic tattoo eyebrows. And I got an idea that in place of eye liner and all I can try out the natural looking cosmetic tattoo eyebrows. So I want to know that what are they made up of and how long they stay on eyes?
