Picture of Stretch Marks: White Striae, Axilla
Stretch marks (striae distensae), are lines on the skin due to the tearing of tissue under the skin's surface. The tears occur due to rapid growth or over-stretching. Stretch marks are very common; 70% of adolescent girls and 40% of boys have stretch marks. Stretch marks are also common in pregnant women, body builders, and those who are obese.
Stretch marks are pink or purple in color, but tend to fade to a paler white over time. They are typically several centimeters long. Treatments for stretch marks including creams, moisturing oils, chemical peels, and skin needling range from minimally helpful to ineffective. Makeup may help conceal the appearance of stretch marks.
