Hi! From the photos, that white flaky/crusty buildup on and around your nose looks like classic seborrheic dermatitis — common in oily areas like the sides of the nose. It’s often triggered by skin yeast (Malassezia), excess oil, dry weather, or stress.
Quick help while you get checked:
- Gentle cleanse (no harsh scrubs)
- Moisturize with something simple like ceramide cream
- Try diluted ketoconazole shampoo as a short face wash or 1% hydrocortisone cream for a few days
I’m not a doctor — this isn’t medical advice. See a dermatologist soon for proper diagnosis and treatment if it keeps coming back. Feel better!
