How can I restore my foreskin while I'm still growing?

Hello, I'm a bit concerned about restoring my foreskin, and reverting back to the way nature intended, but the problem is I began puberty late around my junior year in high school and I'm 17 now, and growth is possibly is still going on as far as my reproductive area is concerned.Any insight on how this may affect me, because I'm considering purchasing one of those foreskin restoration products, thanks in advance.
