A 20-year-old Brazilian student developed an allergy that caused her face to swell up severely after a severe allergic reaction to a product designed to dissolve lip fillers. She had a terrifying reaction after hyaluronidase was injected into her lip earlier this month.

A psychology student posted footage of the horrific incident on TikTok In a clip that garnered 1.5 million views, Isis needed to melt her filler after one side of her lip appeared fuller.

She told local media, “At first we tried to shape it, because hyaluronic acid in the early days can form, but there was an excessive build-up of the product and it didn’t work, then we also tried perforations to put pressure on it, but it didn’t work and then the last time I went, we applied hyaluronidase, which I later learned has a very strong allergenic potential.”
