More whiteheads on the face, i.e. more whiteheads acne, are mainly related to increased androgen levels, increased sebum secretion, and abnormal skin keratinization. 1. Increased androgen levels. When the level of androgens in the body increases, it will stimulate the sebaceous glands to secrete sebum and promote the production of free fatty acids in the skin cells. At this time, the hair follicles and cortical ducts will be over-keratinized, which will lead to clogging of the pores, and the accumulation of sebum in the pores will lead to the formation of whiteheads and pimples. 2. Increased sebum secretion. When the sebum secretion of the skin increases, it will absorb the oxygen in the air to form a viscous liquid which is not easy to be discharged, and will lead to the formation of whiteheads after clogging the pores. 3. Abnormal skin keratinization. Abnormal keratinization of the sebaceous gland ducts and hair follicles can also lead to the formation of whiteheads when the pores are clogged. The formation of whiteheads is also related to bad habits, improper facial cleansing, etc. If the skin has more whiteheads and pimples, pustules, pus blisters and other changes, it is necessary to consult a doctor for standardized treatment in a timely manner.
