I have a chicken pox scar ob my uppee right cheek. It is circular in shape and pretty dented. I can covee it with concealer but I'm concerned with the dent. If I go for acar removal surgery, how likely for the surgery to worsen my scar given the location or to not correct it at all? If I do get one and it got worse/not get corrected, how soon can I have another revision? Will another revision be a wise option in case that happens?
