A lot of small pimples on the forehead are considered the most likely cause of acne, the cause of the disease is not yet clear, usually associated with excessive sebum secretion, follicle sebaceous gland duct abnormal keratinization, bacterial infection and other factors.
1. Excessive sebum secretion: Excessive sebum secretion is the pathological basis for the development of this disease. Abnormal secretion of androgens in the body can lead to exuberant sebaceous gland function and increase sebum secretion.
2. Abnormal keratinization of follicular sebaceous gland ducts: At the opening of the follicular sebaceous gland ducts, the abnormal proliferation of keratinized cells can lead to narrowing of the hair follicles, or even blockage, which is not conducive to sebaceous gland secretion and excretion, and thus triggers acne.
3. Bacterial infection: the follicular sebaceous gland ducts are over-keratinized, causing local blockage. If the follicular sebaceous glands and their surrounding tissues are infected with Propionibacterium acnes, it will activate the body’s immune system, inducing an inflammatory response, thus causing acne.
It is recommended that patients with forehead acne go to a regular hospital in time, under the guidance of the doctor according to the cause of timely treatment, so that the condition is delayed, resulting in serious consequences.
