What are the causes of scars?
The different types of facial scars have the following causes:
- Keloids are raised, shiny, hairless skin lesions that may be darker than the surrounding skin or reddish-purple. They occur when the body produces too much collagen to heal a wound, causing abnormal growth of skin cells and tissues. The healed wound becomes raised and the scar may extend beyond the edge of the wound. It can be annoying or painful if rubbed.
- Hypertrophic scars often occur 1-2 months after a skin injury or acne breakout. They occur when the body produces too much collagen, causing a raised scar that looks like a keloid, but is not larger than the edge of the original wound. Another important difference between hypertrophic scars and keloids is that hypertrophic scars usually disappear after treatment, while keloids are more likely to recur after treatment.
- Atrophic Acne Scar is a dimple or sunken skin that makes the face look rough and uneven. It is caused by the body not being able to create enough collagen and tissue after losing it from acne or a wound. Acne scars are usually found after having severe acne or inflamed acne. In addition, squeezing acne often increases the risk of acne scars .
- Scar contractures are often caused by burns or scalds, which cause the skin to tighten and pull. If scar contractures are severe, they can affect muscle and nerve function, and can cause the skin or organs to twist or deform.
