According to Dr. Donald Graham: Scar formation is a normal part of the healing process for the skin. It is caused by injuries, diseases, skin conditions, and surgery. Although scars are permanent, they can improve and fade over a two-year period depending on the severity of the injury, size of the wound, and location on the body. They are unlikely to fade further after this point. Some people are also predisposed to developing severe scars, with age, heredity, and ethnicity all influencing scar formation.

Applying antibacterial ointments or petroleum jelly to keep the skin moist, changing bandages daily to keep the area clean, avoiding scab picking, and limiting sun exposure to the injured area are all common recommendations for minimizing scar formation. Despite these precautions, scarring is frequently unpredictable and can take many forms, including flat, stretched, depressed, and raised. Scarring can be aggravating and have a negative impact on one's quality of life.

A number of treatment options are available to help improve the appearance of scars and reduce associated discomfort. Scars should also be treated for pain, itching, restriction of movement, and psychosocial distress. The type of scar will also influence the treatment recommended by your plastic surgeon or dermatologist.
