Hi welcome to Health care magic forum.
Thanks for asking a question to H.C.M.F.
You are suffering with
acne, itching, no sebum or pus, fat in it.
Acne is an age related infection, in females may be the harmones play a role, sedantary life style, exposure to dust, using cosmatics by changing brands every time may be the causes.
I advise you to
consult a dermatologist for diagnosis and treatment.
Have more of the foods containing vitaminA and C, like carrot,tomato, fruits and juices.
Avoid more of spices,junk foods, and oily foods.
Wishing for a quick and complete recovery.
Best regards.
