How to remove collagen injection? (Photos)

Thank you for your question. Collagen is typically easily fully absorbed or resolved. You should broach this topic with your injector/board certified facial plastic surgeon. More information would be helpful. If you are early in your recovery, then you should remain patient and follow your post op care instructions.
Best wishes,

There's usually not a need to remove collagen as it readily dissolves and is not generally considered a long lasting filler. If it has been a long time since your injection - then you may have been injected with some other unknown product. You need to speak with your injector and find out what exactly was used. Best wishes, Dr. Aldo

Thank you for sharing your question and photographs.  Depending on the timing of your collagen injections it should have been fully absorbed or dissolved.  I would discuss your current results with your injector to know exactly what was placed in your lip.  If another material, such as silicone, was placed you may require surgery to remove the lump.
