Stretch Marks
Causes
Stretch marks are a form of scarring. When the skin is overstretched and collagen production is disrupted, a type of scar forms. They are generally associated with pregnancy, obesity, puberty, and intense physical activity.
Stretch marks first appear as reddish or purple lines, but tend to gradually fade to a lighter colour. They can appear anywhere on the body, especially in areas where larger amounts of fat is stored, such as abdomen (especially near the belly button), breasts, upper arms, underarms, thighs (both inner and outer), hips, and buttocks.
Most people find the appearance of stretch marks unpleasant. Many try creams, lotions, and other products to prevent or cure stretch marks. Unfortunately, most are unlikely to help
