Pimples are also known as acne. When red pimples appear, they can be removed using general treatment, medication, and physical therapy as necessary. 1. General treatment: keep the local skin clean and dry, avoid prolonged exposure to the sun, avoid staying up late, drinking alcohol, and eat a healthy diet, avoiding foods that are high in sugar, greasy, spicy and stimulating. 2. Medication: Adapalene gel, benzoyl peroxide, fusidic acid cream, etc. can be used as prescribed by the doctor for topical application, and in severe cases, minocycline, doxycycline, isotretinoin, etc. can be combined with oral medication. 3. Physical therapy: If necessary, red and blue light, photodynamic therapy, laser therapy and other physical therapy can also be taken. It is recommended that people with serious or recurring symptoms should go to the hospital in time and follow the doctor’s instructions to avoid delaying the condition.
