Lauren Smalley, who suffers from body dysmorphic disorder and began using lip filler in her teenage years, has been left severely damaged after overexposure to a chemical contained in it.
The chemical, Bio-Alcamid, apparently caused tumours called granulomas to form on her face.
When she was hospitalised with suspected septicaemia, a surgeon had to completely remove the product from her top lip.
Talking to The Sun, Smalley said: "Bio-Alcamid has left me dreadfully scarred and I feel deformed now.
"I'd like to tell anyone who is considering using lip fillers to be careful."
Having had six fat grafts for her damaged top lip, she plans to continue lip reconstruction.
