It's been about a year since I had laser hair removal, and I had it done at a plastic surgery/dermatology clinic!
I had it done in three areas: the arms, armpits, and philtrum. The growth rate has definitely slowed down, and the hair itself has become very thin, just like when it first grew, so it doesn't really bother me.
I was concerned that the philtrum would grow back thin even after I removed the hair, so I shaved it off with an eyebrow knife, but it was okay because the growth was definitely slow and thin.
