Botox and Sculptra can, and often is, injected during the same treatment session. They are injected in different anatomic planes, and do not interact with each other.
I believe you are asking if Botox and Sculptra can be performed during the same visit to your dermatologist. The answer is yes. I often treat the patient with fillers such as Sculptra and Juvederm followed by Botox. Occasionally Sculptra can cause immediate swelling and at times this makes it difficult to injext Botox/Dysport properly. If there is a lot of swelling I urge my patients to come back a few days later.
