Stretch Marks and Scars
Scar tissue are areas of fibrous tissue that replace normal skin after an injury or surgery. They form as part of the natural healing process but can vary in appearance, from raised and thick (hypertrophic or keloid scars) to flat and discoloured (atrophic scars). Stretch marks, or striae, are linear scars that occur when the skin is stretched rapidly due to various factors, leading to a breakdown of collagen and elastin .
