I have rarely seen patients who experience skin problems for longer than 4 months after rhinoplasty. I also agree that the immediate and short term problems that we see are generally due to swelling, and occlusion caused by the tape used on the skin after surgery.
My advice to most of my patients, especially those with oily or acne prone skin, is to have a facial to clear the pores of the nose one to two weeks prior to surgery. T
This has also helped in improving our rate of satisfaction with the scars that are occasionally placed at the junction of the nostril and the cheek to reduce or narrow the nostrils. In fact, I rarely preform a reduction of this area without a preceding facial.
Remember that your skin will be very sensitive to the sun, and may even be more sensitive to skin products or make-up that can clog the pores after surgery. This may last for several months, so it is certainly advisable to use a light non-comedogenic sunblock for several months.
I hope this helps you in your recovery.
