Depends, the first time you wax you normally get a little rash for a little while - few days. Just where the hair/skin aint used to it. After that its cool when you wax it after.
I remeber once when a girl I was seeing done her eye brows for the first time (rather than plucking) it looked like I had been abusing her lol
Do your chest next time and see how it goes, then take it elsewhere
