Product to renew skin?

Hello there, my plastic surgeon after a nose job he gave me some sessions where he applied a very strong product in my nose to regenerate the skin, the product was so strong that for one week the skin gets literally burned and then it falls leaving the new skin. I don't live in that country anymore and he wont gave me the product name, apparently can be only used by doctors. Anyhow I am looking for a product that I can buy (preferably in the internet) that will do the same or some what the same. Any suggestions? thank you in advance.
