After reading your query it appears the possibility of "Seborrheic dermatitis”.
This is a condition in which there is flaky skin condition along with abnormal activity of oil glands. This is common manifestation on scalp a dandruff and on face as flakes over side of nose and over chin area.
For the betterment you can follow the suggestions as below:

in a vey thin layer over the affected area.
-You can do cold water compresses to reduce the intensity of itching.
