Hypertrophic scars are red raised lumps on the skin that are confined to the boundaries of the original wound. Although some are permanent, they can almost disappear after a few years.9

Keloid scars are large scars that constantly grow and often form into large, tumorous, benign growths and are most common in dark-skinned people. They can be caused by surgery; injuries; skin issues, such as acne; or body piercings, particularly on the ear lobes. A favorite site for keloids is the shoulders and the chest.9

Pitted scars are sunken recesses in the skin caused when underlying structures supporting the skin, such as fat or muscle, are lost, and are most commonly associated with acne and chicken pox.9

The average age of onset for keloids has been estimated to be approximately 22 years for both women and men. Specific body areas that are more prone to scars include areas with sebaceous glands that secrete oil or areas of high skin tension. They include the shoulders, chest, neck, upper back, ears and upper arms.10

Stretch marks, or striae, are also scars that can take many forms. They occur more frequently in females during adolescence and weight gain.
