I got an allergyㅠㅠ

I came back to my parents' house and got Rejuran at a nearby dermatologist. But I got an allergy. My skin wasn't that bad to begin with, but it got better and I got a skin booster, but my skin got really bad because of the allergy. It's so sad.

I'm taking allergy medication, but I haven't seen any improvement yet. Has anyone else experienced allergies after using Skin Booster like I did? I searched a lot on blogs and YouTube, and there were a few cases like mine. They said it wasn't a problem with the hospital, but rather that their skin didn't match Rejuran or their condition wasn't good. I guess there's no such thing as a procedure with absolutely no side effects.

If there are any seniors who have had allergies after cosmetic procedures, I'm curious about how long it took for them to go away and how they were treated😭
