Hi, I have a chickenpox scar on my nose since i was 10, I'm 23 now. Been to a skin clinic to do something about the scar, it appears greyish black, done a biopsy test, and the hyperpigmentation is deep within the dermis. I have done 2 times of laser on it and applied hydroquinone for about a month. But it still remains unchanged, are there any other options? I'm getting very depressed about it
