Is it permissible to drive a friend to a cosmetic clinic for procedures such as Botox, knowing that she is from another governorate and expects help, and that the questioner used to undergo these procedures herself but has repented from them?

Injections and other medical procedures used for body beautification are permissible if they are for removing harm or treating a disfiguring defect; otherwise, they are not. It is not permissible to remove wrinkles by surgery or injection unless it is a medical condition, provided there is no risk of harm. If your friend's intention is to remove harm or treat a disfiguring defect, there is no harm in assisting her. However, if her purpose is merely improvement and beautification, then it is not permissible to assist her.
