acne scar on my cheek from pimple squeezing

I am 27 years old and I have many very noticeable acne scar on my cheek that resulted when I picked a large drying pimple on my cheek about a year ago. I would like to have an acne scar revision done and I would like to know if I can do it because I am 27 years old??
I have already got information about the cost, which is not costly at all, I am thinking of doing it at a Cosmetology & Plastic Surgery Hospital [link removed] they seem to be specialized in this domain and this is what drives my attention to them. I hope that everything will go on well.
