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.  

 Hi, ask the MD that augmented your lips what dermal filler was used.  Any HA filler can be dissolved using injections of hyaluronidase.  Collagen can't be dissolved, nor can some of the other (obviously permanent ones) dermal fillers like Radiesse (which is too thick for lip augmentation in my humble opinion).
 I have performed many lip augmentation procedures using dermal fillers or lip implants for over 30 years. Following my beauty principles, the upper lip should be approximately 75 % the size of the lower lip for the lips to appear balanced. The lips can be augmented using a dermal filler or a Permalip implant.
 Dermal filers and lip implants offer a much more reliable volume for augmentation of the lips than permanent fillers or fat injections which are associated with increased, unwanted, side effects.
Hope this helps.
