Can I use witch hazel on my nose one week post rhinoplasty to clear up blackheads and blocked pores?

I had rhinoplasty 11 days ago, the skin on my nose is in a bad state with a lot of blackheads, some whiteheads and goes between very oily to very dry each day, I was told that witch hazel is great to use for clearing up skin problems, can I use this on my nose or is it too harsh? If I can do I just apply it straight to my nose or should I wash with soap and water first then apply and leave it on? Thank you for your advice.
