Overview
Scar
What are Scars?
Scars form as part of the natural healing process after the skin has been cut or damaged. The skin repairs itself by growing new tissue to close the wound and fill in any gaps caused by the injury. This new tissue, known as scar tissue, is primarily composed of a protein called collagen. Scars can vary in appearance, size, and severity, ranging from large and painful to barely visible. Certain individuals, particularly those with darker skin or red hair, are more prone to developing keloid scars, which are raised and extend beyond the original injury site.
Types of Scars
Scars can develop in different forms and locations on the body. The common types of scars include:
- Contracture Scars: Typically develop after a burn, causing the skin to tighten and potentially impair movement.
- Depressed (Atrophic) Scars: Sunken scars often resulting from chickenpox or acne, appearing as small indentations.
- Flat Scars: Initially raised but flatten over time, often pink or red, and may change color as they heal.
- Keloids: Raised, overgrown scar tissue that extends beyond the injured area, potentially affecting movement.
- Raised (Hypertrophic) Scars: Raised but do not extend beyond the original wound, often shrinking over time.
- Stretch Marks: Caused by rapid skin stretching or shrinking, commonly occurring during pregnancy, puberty, or significant weight changes.
