Discoloration or surface irregularities and other more subtle scars can be cosmetically improved by surgery or other treatments recommended by your plastic surgeon. These types of scars do not impair function or cause physical discomfort and include acne scars as well as scars resulting from minor injury and prior surgical incisions.
Hypertrophic scars are thick clusters of scar tissue that develop directly at a wound site. They are often raised, red and/or uncomfortable and may become wider over time. They can be hyperpigmented (darker in colour) or hypopigmented (lighter in colour).
Keloids are larger than hypertrophic scars. They can be painful or itchy and may even pucker. They extend beyond the edges of the original wound. Keloids can occur anywhere, but they develop more commonly where there is little underlying fatty tissue, such as on the face, neck, ears, chest or shoulders.
Contractures are scars that restrict movement due to skin and underlying tissue that pull together during healing. They can occur when there is a large amount of tissue loss, such as after a burn. Contractures also can form where a wound cross a joint, restricting movement of the fingers, elbows, knees or neck.
