Common scar types include: ● Hypertrophic scars - These scars are raised and appear red or pink. Hypertrophic scars occur due to an overproduction of collagen during the healing process. ● Atrophic scars - Atrophic scars are sunken into the skin. They can be caused by conditions like acne and chickenpox. ● Keloid scars - Similar to hypertrophic scars, keloid scars are raised and extend beyond the original wound site. These can be itchy, and painful, and continue to grow even after the wound has healed. ● Contracture scars - This type of scar occurs when the skin tightens and restricts movement due to a significant loss of tissue, such as from burns. These scars can affect the underlying muscles and tendons. ● Stretch marks - Although not considered traditional scars, stretch marks are a form of skin scarring that occurs due to rapid stretching of the skin, commonly seen during pregnancy, puberty, and weight gain.
