What causes deep scars?
Deep scars can develop as a result of several skin disorders and conditions, including acne and dermatitis. Other causes of deep scars include an injury caused by blunt trauma that ruptures underlying tissue layers, such as a burn or mastectomy operation.
Types of Scars
There are two types of deep scars, hypertrophic and keloid scars.
- Hypertrophic scars are caused by the excessive production of collagen in the skin. This results in raised or thickened scar tissue that can be felt under the skin. Hypertrophic scars usually fade over time.
- Keloid scars are caused by excess growth of the dermis, which is the middle layer of the skin. Keloid scars can also be felt under the skin and cause discomfort or itching. Keloid scars may remain for many years after an injury heals and can grow as large as four inches in diameter.
Surface scarring is the most common type of scarring. It may appear raised or flat, red or white, and can be small or large. Surface scars are usually soft, feel like normal skin, and can become smooth over time.
Deep scarring is a major concern for many men and women. Deep scarring can result from surgery, especially with underlying acne or inflammation. It also may be caused by severe overuse of corticosteroid creams or using irritating products on damaged, sensitive skin.
