I was fine for five years with teosyal with another beautician. Why did this happen?

I changed who does my fillers and had someone new, they used teosyal kiss. Wen I had them done I had swelling, nothing unusual to wat I was used to. Then after 4 days one side swelled more and so did above my lip and face, the swelling was getting worse and the main lump of the swelling went hard and painful . Day 8 I was given steroids by a doctor the beautician worked for and he also injected a large amount of hyaluronic acid and it sorted the problem. i ws told I cant use Teyestol anymore.
