Eating hot pot does not usually cause acne, but eating spicy and stimulating hot pot for a long time can increase the risk of acne. Pimples, also known as acne, are mostly caused by abnormally high androgen levels in the body, resulting in increased sebum secretion from the skin on the face, thus forming acne; secondly, abnormal keratinization of the cells around the skin on the face leads to the follicle opening becoming smaller and narrower, so that sebum can not be excreted, thus accumulating and forming pimples; or there is a localized infection and propagation of Propionibacterium acnes, which can also induce the appearance of acne. Generally speaking, simply eating hot pot occasionally does not cause acne, but patients who eat hot pot for a long time, especially spicy and stimulating as well as greasy hot pot, can aggravate the secretion of oil in the skin, coupled with the lack of attention to the cleansing of the skin on the face, it is easy to lead to the hair follicles of the face being clogged with sebum, which can induce or aggravate the condition of acne. Therefore, in daily life, we should pay attention to a light diet, avoid long-term intake of spicy and stimulating food, and pay attention to local skin cleaning, keep the skin fresh and hygienic, can play a role in preventing acne. Acne need to go to the hospital in time, do not self-medication, so as not to cause damage to the body.
