It was my first time getting it, but I understood the unpleasant pain in the reviews. First, when the needle goes in, it feels a little prickly like getting a vaccination, but the injection of the drug feels strange. I can feel water filling my face in real time, and it hurts like a bruise for about 10 minutes after the procedure. But the swelling went down faster than I thought. After 3 hours, I was able to go about my daily life.
