About a year ago, I had forehead filler done at Refill Up. I had the filler done at another hospital, but as soon as I got it done, it kept getting lumpy, so I got a refund within a week and had it done again at this hospital at the recommendation of an acquaintance (they say it was a place that spread word of mouth among stewardesses). The other hospital had forehead filler 100%. It was 10,000 won, but the refill was 700,000 won, and the remaining 300,000 won was used for thread lifting. I'm still satisfied now
