Pay attention to observation: first of all, you can observe the situation of acne. Some scars will gradually fade and flatten over time, and will not affect the body function. If acne does not cause any discomfort or affect your daily life, you can choose to accept its existence.

Keep clean: It is important to keep the wound clean and dry. Wash the wound gently with mild soap and water, and then pat it dry with a clean towel.

Use skin care products: Try using some skin care products to help reduce the appearance of acne. For example, apply vitamin E oil, aloe vera gel or professional products to help scar repair. These products may help to soften scar tissue and promote the growth of new cells.

Massage: Gently massaging the acne area also helps to improve blood circulation and tissue repair. You can gently massage the acne area with your fingertips for a few minutes every day.

Medical intervention: If acne causes obvious troubles to your appearance or function, consider consulting a doctor or dermatologist. They may suggest some professional treatments, such as laser therapy, minimally invasive surgery or injection of scar tissue dissolving agent.
