I had IPL hair removal done to my underarms and I am so glad that I did! I had very course hair with quick growth and was sick of shaving as I would often develop ingrown hairs.
After my first session (which did sting) I was red for a couple of hours but it went away. The results after a couple of weeks was great! I had significantly less hair growth and no ingrowns.
I have gone back 6 times and now only have to go back for 4month maintainences. I am no longer embarrassed to lift up my arms, my armpits are smooth and hairfree :)
