I too have had radiesse injections in the past and never had an issue. on July 12th of this year, i had it injected using a "new method" of injecting, but with the same product. This method is done for nasolabial lines but instead of injecting in the obvious area, tape was placed across my cheeks and he pulled the skin tight toward my temple area and then injected into my head. first words out of his mouth were, oops, we got a blood vessel. What the hell? let me just tell you that it caused severe swelling, bruising, my skin peeled, and then my hair fell out in that area. Some is growing back, but there is an area about the size of a lemon that is still smooth. No hair there, and the skin is numb, but if i push on it, it is extremely painful. Headaches, vertigo, and sinus infectionSSSS, ever since this happened. They are telling me I have alopecia. Are you kidding me????????
