Chest acne refers to acne, which can be removed by general treatment, medication or physical means. 1. General treatment: In life, patients should develop good habits, eat less high sugar, high fat diet, avoid staying up late and excessive fatigue, remove makeup in time and choose to use the appropriate cleansing products, and do a good job of personal hygiene and clean care. 2. Medication: patients can also choose to use topical fusidic acid cream, azelaic acid gel for treatment under the guidance of a professional doctor, or by taking isotretinoin soft capsules and other systemic medications for treatment. 3. Physical therapy: Physical means such as photodynamic therapy or laser therapy can also be effective in removing the symptoms of chest acne, but it should be noted that there may be pain, scabs, erythema and hyperpigmentation and other adverse reactions. If the general treatment is not effective in improving the situation of chest acne, you need to be under the guidance of a professional doctor and individualized treatment, to avoid delaying the condition, leading to continued aggravation of the symptoms, resulting in serious adverse effects.
