What can I do to stop the burning and peeling!!!!

Hi everybody, I only just signed up so here's my problem

Im twelve years old I will be 13 on June 18. I've had acne since last year and the doctor prescribed Differin Gel last monday, it was fine the first few days but my skin now becomes really tight and dry and peels when I put it on, I was wondering can I put vaseline or moisturiser on before or after the gel to loosten up my face and stop the hurting when I speak and stuff!

Thanks!!
