Scars Range in Size and Overall Appearance
Thin, flat scars do not usually cause a lot of physical or emotional distress once they are healed. However, they can grow wider if they are located in areas where there is constant movement, such as your knee.
Unlike flat scars, keloid scars are puffy and stick out from the surrounding skin. In some cases, they cause itching and discomfort. Keloids are often difficult to treat with over-the-counter remedies.
These scars look similar to keloids and are typically raised and red. But unlike keloids, they do not spread outside of the injury site.
Severe burns not only take a long time to heal from. They can create permanent scars called contractures, in which substantial tissue loss has occurred.
