Early pregnancy forehead pimples are mostly acne, mainly due to abnormal androgen levels, exuberant sebum secretion, abnormal keratinization of cells around hair follicles and other etiological factors.
1. Abnormal androgen levels: Usually during pregnancy, it is easy to cause hormone imbalance, androgen levels are elevated or relatively elevated, thus affecting the function of sebaceous glands, sebum secretion is excessive, and acne is easily formed.
2. Excessive sebum secretion: Due to hot environment, spicy diet, late night, bad mental condition, etc., it is easy to stimulate the sebaceous glands to secrete excess sebum, which accumulates at the mouth of the hair follicles and forms acne.
3. Abnormal keratinization of perifollicular cells: Abnormal keratinization of perifollicular cells leads to the follicular opening becoming smaller, narrower, and blocked, and sebum is not easy to be discharged, thus remaining in the follicular opening, which is infected by germs and forms acne.
Acne on the forehead at the beginning of pregnancy is a common phenomenon, it is recommended that patients according to their own situation, if necessary, to the regular hospital consultation and treatment, usually pay attention to ensure that sleep, keep in a good mood, avoid staying up too late or too much pressure.
