3 weeks after Sculptra my face is huge and so puffy I can hardly open my eyes. I'm scared and distraught. (photos)

Swelling isn't normal after scuptra, at least not amounts that persist.  Please see your physician or an expert for an evaluation.  Best, Dr. Emer

This is absolutely not normal and needs immediate attention. I would first consider an infection as the cause of this. I recommend against any dental procedures for about 2 weeks after any filler injections because the bacteria from the mouth can spread to the face. Do you have any source for an infection? This needs antibiotics and steroids probably. Don't sit on this.

It is a little unusual to see a delayed onset allergic reaction to any product, injectible or otherwise, as most allergic reactions occur immediately after exposure, so may or may not be related.  If it seems to be getting worse, you really should schedule an appointment with your injection provider and your primary MD as well to ensure you are not having an allergic reaction to the product and if not, what you ARE reacting too. Something is obviously causing your symptoms and often this can be treated with a short course of oral steroids.  If you start to have more severe symptoms such as tongue swelling, difficulty breathing, etc. you should go to the Emergency Room.  Good luck!

You may be having an allergic, adverse reaction or infection from your injections. This is extremely rare. Seek medical advice asap and consider steroids, anti-histamines and/ or antibiotics for treatment. This does not appear to be consistent with a normal, average injection recovery. Of course, you may have an underlying medical condition, totally unrelated to your injection. Your internist should work up the problem and refer you to the appropriate specialist for treatment. 

Seems you need steroid Rx and possible antibiotic Rx also. But only in person examination allows a determination of the issues.
