Acne scars are characterized by permanent damage left after inflammation, hyperpigmentation left behind by the damage during the repair process, slow fading, and in some cases, permanent acne scars. Acne scars are usually scar tissue left behind after acne heals and can be hyperpigmented. Some acne scars will fade over time or even metabolize and disappear, while others will leave permanent scars under the skin. It is recommended that patients do not pick with their hands during the growth of acne, and eat a light diet and have a regular routine to avoid leaving acne scars. If acne marks have formed, consider visiting a hospital dermatologist. If the acne scars are permanent, you can consider using medical aesthetic means to repair or make-up to cover them. If the patient’s acne scars are severe, or affect their appearance and continue to be unhealthy, they should go to the hospital for treatment in a timely manner.
