food

Irritating foods such as high fat, high sugar, acid and spicy food may aggravate acne. Although some reports disapprove of this view, some patients' deterioration is related to food.

Endocrine (hormonal) effects

In addition to androgen, the increase of lutein in women before menstruation, that is, about two weeks from ovulation to the next physiological period, may lead to the aggravation of acne.

Acne Bacillus

Propionibacterium acnes itself is not pathogenic, but it can promote keratinization of pore openings, lead to pore blockage and induce acne.

No acne on your face doesn't mean you don't have pimples. It will exist in the skin on weekdays. When sebum is blocked and accumulated in hair follicles, Acne bacilli will grow and multiply rapidly, causing inflammation in hair follicles and their surroundings.
