Red acne marks usually disappear on their own. Acne marks are caused by skin infections caused by the acne itself, or by excessive squeezing over a long period of time, resulting in damage to the skin’s surface tissue and hyperpigmentation. Pimple marks usually start out as light red or red and gradually turn black or dark brown as time goes on. As the skin itself has a certain metabolic ability, it has the ability to repair its own pigmentation, and red acne marks can generally fade and disappear with time. If you want to speed up the recovery process of red acne marks, you can usually eat more fruits rich in vitamin C, such as oranges, kiwi, etc. You can also go to the hospital dermatology department and have the doctor prescribe relevant repair creams to promote the disappearance of red acne marks. During the recovery period of acne marks, patients should pay attention to sun protection when they go out, such as playing umbrella, wearing sun hat, using sunscreen, etc.
