Acne mostly occurs on the face, varying from mild to severe. Generally, there are some red, painful papules, and some may have white pustular papules. In such cases, try not to squeeze them. For some people with poor skin, acne scars or pits may form in the later stages, making treatment more troublesome. After the onset of acne, it is crucial to seek proper treatment at a dermatology department of a formal hospital. Oral and topical anti-inflammatory medications along with agents that clear internal heat should be used. Local treatment may involve red and blue light therapy. If there are indeed many pustules, a comedone extractor can be used to clean them appropriately. After recovery, it is important to avoid spicy and irritating foods, avoid staying up late, exercise regularly, and enhance immunity. (Specific medications should be taken under the guidance of a physician.)
