Why Scars Occur?
Scars may form from many different reasons, including as a result of infections, surgery, injuries, or inflammation of tissue.
Scars, the result of the body’s natural healing process after injury or skin conditions, are areas of fibrous tissue that replace normal skin. They are composed of collagen, similar to the tissue they replace, but their composition differs from normal tissue.
Types of Scars and Their Characteristics
Hypertrophic and Keloid Scarring
Hypertrophic scars occur when excess collagen production leads to a raised or thickened scar compared to the surrounding skin. Keloid scars, a type of hypertrophic scar, extend beyond the wound area and are common in dark-skinned individuals. They can be triggered by surgery, accidents, acne, or body piercings, sometimes causing itching or pain. Treatment options for both hypertrophic and keloid scars include silicone sheeting application, corticosteroid injections, and laser treatments to improve their appearance and alleviate associated symptoms.
Atrophic scars create sunken recesses in the skin, often resulting from conditions like acne or chickenpox. These types of scars, including facial scars, can be addressed using topical cosmeceutical creams, collagen induction therapy, or laser skin resurfacing. These approaches stimulate collagen regeneration, leading to improved appearance of atrophic scars.
