It is not unusual to get some swelling after a Sculptra treatment and sometimes it can be more swollen on one side than the other. Normally, after a few days to a week or so, the swelling will subside and both sides will appear more even. The appearance that you have at five days after the treatment will definitely not be the appearance that you have later, as it takes several weeks for the final result to be seen.
After treatment with Sculptra, it is normal to have a certain degree of swelling associated with the procedure itself that will last from hours to days. It's a good idea to massage the treated areas in a circular motion several times a day during the early post-procedure period to ensure uniform distribution of the product. It takes weeks for the effect of collagen production to show permanent changes in your facial volume. The swelling you are experiencing now is likely temporary, but if it persists more than a week, follow up with your doctor.
