Acne may be related to excessive sebum secretion and propagation of Propionibacterium acnes, etc. From the perspective of Western medicine, there is no study that shows a relationship between acne and heavy dampness. The pathogenesis of acne has not yet been fully elucidated. Studies have shown that heredity, excessive sebum secretion, keratinization of follicular sebaceous gland ducts, propagation of Propionibacterium acnes, and immunity are all factors that may be related to acne. Dampness belongs to the concept of Traditional Chinese Medicine (TCM), and there is no clear correlation between acne and dampness from the Western medical point of view. Apart from the above factors, acne can also be affected by endocrine, emotional and dietary factors. If you have acne on your face, it is advisable to visit a hospital as soon as possible.
