1. Trauma to the Skin: During surgery, trauma to the skin can activate sebaceous glands, leading to increased oil production to keep the skin moisturized.
2. Use of Adhesives and Dressings: The use of adhesives, dressings, and other materials during the recovery period can block skin pores and contribute to increased oil production.
3. Stress and Hormonal Changes: Stress and hormonal fluctuations associated with surgery and recovery can impact sebaceous gland activity.
4. Swelling and Inflammation: Swelling and inflammation during the healing process can also affect changes in skin texture.

Managing Oily Skin:

1. Use a Mild Cleanser: Wash your face twice daily with a mild, hypoallergenic cleanser.
2. Use a Toner or Astringent: Apply a toner or astringent to control oil and keep pores clear.
3. Use a Lightweight Moisturizer: Use a lightweight moisturizer to keep your skin hydrated without clogging pores.
4. Avoid Heavy Makeup: Refrain from using heavy makeup that may further block pores and exacerbate oiliness.

Having purple skin after rhinoplasty is generally common during the healing process.
