what causes a scar to form
Though scar tissue is made up of the same substance as undamaged skin, it looks different because of the way the fibers in the tissue are arranged. Scars form every time the skin is damaged beyond its first layer, whether that damage comes from a cut, burn, or a skin condition like acne or a fungal infection.
CAUSES & TYPES OF SCARRING. It is estimated that, on average, an individual has three scars on their body. Most scars can be attributed to everyday cuts, grazes and minor burns (34%). The remaining causes of scars include hospital surgery (20%), trauma (15%), elective surgery (15%), cosmetic surgery (10%) and mole removal (6%).
