Patients with acne can drink milk. Milk contains high protein, calcium, iron, and zinc, which have certain therapeutic effects on acne. Drinking milk does not exacerbate or cause a recurrence of acne. Acne is related to vigorous secretion of sebaceous glands or local skin infection by Propionibacterium acnes. Once the disease occurs, it must be treated according to standards. Avoid spicy and irritating foods, do not stay up late, and you can take oral and topical anti-inflammatory drugs. Combining red and blue light treatments can hasten recovery. Try not to use cosmetics indiscriminately, especially those that are greasy and likely to clog pores. During treatment, try not to scratch or pop pimples, as this can lead to pigmentation or scarring. (Specific medication should be conducted under the guidance of a physician.)
