Sebum production and the skin type · seborrhoeic dermatitis and inflammatory causes · hormonal causes of adult-onset oiliness
Dr. Yongbo Jia is Deputy Director of the Plastic Surgery & Aesthetics Medical Center and head of its dermatology service at Chongqing West District Hospital, and he is the physician responsible for this site. A vice chief physician and licensed aesthetic attending, he graduated from Chengdu University of Traditional Chinese Medicine and trained in dermatology at the Institute of Dermatology, Chinese Academy of Medical Sciences, and at Chongqing Hospital of Traditional Chinese Medicine.
On this site his part is the distinction between a skin type and a condition. He assesses where the oil sits and when it appears, reads the routine for the rebound that over-cleansing produces, looks specifically for the flaking, redness and itching that point to seborrhoeic dermatitis rather than to ordinary sebum, and arranges a hormonal investigation when the history justifies one. He treats the answer — including the answer that a normal skin type should be left alone — and he declines to escalate a routine into prescription treatment before the simple steps have had a fair trial. His stated discipline is to correct the routine before adding anything to it.

A skin type is not a disease
Oily skin is inherited, it is not caused by dirt, and it does not have to be treated. The work of an assessment is to establish whether what you have is a skin type, a routine that is making it worse, or a condition such as seborrhoeic dermatitis that imitates one. Those three are answered differently, and only one of them usually needs a prescription.
