Our skin can easily be injured. By small cuts and scrapes, but also by burns, corrosions or surgery. Tiny superficial injuries heal completely, but deep or extensive wounds set off a complex healing process in the body - leaving scars behind. This tissue has lost its elasticity and is often lighter in colour.
Hair, sebaceous and sweat glands are missing. Treatment should start promptly, but something can also be done for old scars. For disfiguring and extensive scars surgery can help, while simpler alternatives are available in the form of medications and ointments.
When too much connective tissue forms, scars have a bulging appearance and extend beyond the healthy skin; these are hypertrophic scars. They develop more easily if the healing wound is often under tension. Some people may also have an inherited tendency to hypertrophic scars.
Here too, excess connective tissue is the cause of keloids. But these proliferate even further, extend beyond the edge of the scar and are hard and reddened. Keloid scars also cause itching, and are seen mainly in children, young women and dark skinned people.
