After voluma injections into my cheeks they turned bright red. Is this normal, or could it be an allergic reaction?

This can be from allergy, injection technique, or a combination.  If this has subsided it was likely only a local reaction from the treatment.  If this continues please see someone for an evaluation.  Best, Dr. Emer.

Thank you for your question.  It is normal to have a small amount of redness following injections of Voluma, but redness does not usually persist for two weeks.  It would be best to speak with your injector and discuss your concerns. They will need to know additional information regarding other symptoms you may have had: itching, hives, swelling, pain, etc. to truly know what may have taken place. I am happy to hear that it resolved spontaneously but because Voluma is made of hyaluronic acid (which is present in the body naturally) and because it can last upward of two years, it doesn't sound as if it had been a true allergic reaction, otherwise it should still be happening. Perhaps it was a reaction to a topical numbing medication?  

A reaction would be uncommon but the best thing is to immediately follow up with your injectinmg practitioner. Early redness may be temporary and the best thing is to apply intermittent cold packs until you are seen.

It is impossible without a photo to determine what the redness was immediately after the injection.  It sounds like it was a flushing reaction which can be associated with rosacea or the injection.  Please consult your treating physician upon injection.  Best, Dr. Green

This is a question that should be asked of your practitioner immediately when you notice the redness or anything that you feel is a potential problem.As it has subsided, you are probably okay, but I would suggest you call your physician and let them take a look.
