I tell all my patients who have had filler injections that swelling can last up to two weeks. I wish you the best of luck, Dr. Emer.
Each patient will have different patient experience depending on the patient's specific situation and the skill/technique of the injector. The swelling will range from minimal to significant that can last a couple of weeks. Consult with your injector as he or she knows the scope of the treatment and the specifics about you.
