It hasn’t been a year since my double eyelid surgery, but something like a round lump? pimple.. appeared on my eye It showed up not long after surgery and it won’t go away, ha It’s a side effect, right? It was a revision surgery too There’s really nothing that changed, and only side effects showed up I’m so stressed I did it because they said it was famous
