Dry, flaky skin after rhinoplasty?

I had a rhinoplasty about 2 weeks ago. The skin on tip and the sides of my nose are flaky and dry. I have used several moisturizers but nothing has helped so far. I have been washing my face with lukewarm water, gently with a wet washcloth but the tip of my nose is very sensitive. Any advice? I want to wear makeup, but everything seems to be clinging onto the dry skin patches on my nose, making everything look worse than it is.
