I go there often, but it's always crowded. If you go before 4 PM on weekdays, you don't have to wait long. The last time I went, I saw three people shouting at the counter while waiting, so I decided never to go during rush hour on Fridays or weekends. The doctors change every day, probably because they are trainees, so the injection doesn't just slide right in. It's actually quite painful. It feels like it's being injected deep under the skin, so I always cry while getting it. If you look closely, there is a blue bruise near my eye. It disappears quickly, but my skin looks really nice in exactly three days. It's in perfect condition, so it's great to go out. I highly recommend it!!!
