Persistent acne requires scientific care methods, which can help you effectively manage and reduce acne occurrence. Maintain facial cleanliness: Clean your face with a gentle cleansing product morning and evening every day, and choose cleansing products that do not contain alcohol or fragrances. Avoid over-cleaning to prevent irritating the skin and increasing oil secretion. Use suitable skincare products: Choose skincare products that do not contain oils and are non-comedogenic. Avoid using heavy or irritating skincare products. Regular exfoliation: Use a gentle exfoliating product once or twice a week to help remove dead skin cells and prevent clogged pores. Sustain good living habits. Keep a balanced diet, reduce the intake of high-sugar and high-fat foods, eat more fruits and vegetables. Ensure an adequate sleep, reducing stress, as stress can affect the endocrine, leading to worsened acne. Avoid frequently touching the face: Hands carry many bacteria, touching the face frequently can bring bacteria to the face, causing more severe acne. Avoid squeezing pimples to prevent infection and scarring. Keep the skin moisturized: Use gentle, non-irritating moisturizing products to maintain the skin's moisture balance. Skin that is too dry or too oily will both exacerbate acne problems.
