What causes acne on the skin?« Back to Questions List

The underlying causes of skin acne are excessive sebum production, elevated androgen levels, abnormal keratinization of cells around hair follicles, and proliferation of Propionibacterium acnes, as well as inflammatory reactions, all of which are the underlying causes of acne.

First, acne usually develops during adolescence, and after adolescence the condition tends to remit naturally, and in some cases it can last into adulthood. There are some habits that can trigger or aggravate acne, such as staying up late, overwork, stress, tension, anxiety, etc., which can trigger an increase in sebum secretion and thus produce acne.

Second, eating high-calorie foods such as animal fats, sugar, cocoa, and milk, as well as stimulant foods, can also trigger the onset and worsening of acne.

Third, in women, it may be due to the use of powders such as BB creams, the use of skin care products containing oily ingredients, or the lack of thorough makeup removal, all of which can aggravate acne.
