Blackheads are considered to be caused by dietary factors, environmental factors, endocrine disorders and other reasons.
1. Dietary factors: If you have an irregular diet or often eat greasy, sugary food, it will lead to exuberant sebaceous gland secretion, which will cause excessive oil secretion and block the local pores, so that the patient will have the symptom of blackheads.
2. Environmental factors: If you often apply oily foundation cream, foundation liquid, and long time in the high temperature environment, foundation cream, foundation liquid is easy to block the pores, so as to form the local blackhead symptoms.
3. Endocrine disorders: when entering puberty, or after ovulation, the level of androgens in the body will gradually rise, thus stimulating the sebaceous glands to secrete large amounts of oil, when the oil mixed with the shedding of epidermis clogging the pores, blackheads will be formed.
When blackheads appear locally, you can cooperate with your doctor to give targeted treatment to avoid adverse reactions after the disease.
