Are fillers supposed to leave lumps under the skin?

No, properly placed filler shouldn't leave visible lumps. Some swelling and firmness is normal and will resolve in 1-2 weeks after an injection. If lumps persist, the filler can be reversed with Hyaluronidase and a different technique can be used next time. Best, Dr. Emer

Thank you for your question. It is not uncommon to feel some lumps under the skin after filler injection. The lumps usually reabsorbed with time. You can gently massage them to help smooth them out. If the lumps do not resolve your can have them dissolved with hyaluronidase. Best of Luck!
