Sculptra is a dermal stimulator and in my opinion is best used on places where more fullness is needed such as the cheeks and temples. I have had sculptra placed in my face and even in the best hands it can cause tiny hard bumps. For this reason, I am very cautious with the product and use it only in specific areas of the face. If it is placed along the lower jaw bone you can tiny hard pea sized bumps which takes years to go away. Choose only a very experienced injector.
