The Ordinary lash serum caused a stye

I’m so disappointed omg, I’ve been using the lash serum for 5 days every morning and night, I was already seeing improvement but I just noticed I got a small stye on my top lash line and I’ve been using a warm tea bag to try and get rid of it. I guess I’m gonna have to stop using the serum, I’m so sad about it. I even heard that some people’s lashes FALL OUT after discontinuing it, is there anything I can do to prevent that or regrow them if it happens cause istg I’ll be so pissed. 🥲 has this happened to anyone else?
