Hello:
I don’t know if you had a rhinoplasty, whether it was a prosthesis or an injection. But no matter what it is, it is normal to emit oil. Because of the intervention of foreign objects, the skin itself is engaged in a battle of resistance. During this process, cells will die, and oil is also a product. If it is a prosthesis, you can go to a beauty salon for proper oil control and hydration after about four weeks. Tell your beautician to pay attention to your nose. If it is the latter, there should be a finalization process after two weeks, and you should ask your doctor when you can do skin care. You can't apply it with water at ordinary times. You should buy oil-absorbing paper and absorb it n times a day. Do not eat spicy or greasy food. Try to have a light diet.
Wish you good health
