Fat grafting 2 weeks ago: Long time Retin-A user.

I am a long time user of retin A, I use it mainly to control my acne and clogged pores. 12 days out from fat transfer to the face and I see my pores getting clogged again, shd I go back to retin A? Would it increase swelling and would too much prolonged swelling jeopardize the end results of fat transfer? If I squeeze pimples and blackheads would it also affect fat take? Thanks!
