Stretch marks

Stretch marks vary in color and appearance. They can be classified under two types:

• Red stretch marks (striae rubra) form because of the stretching of the dermal layer of the skin, allowing the blood vessels in the layer below to show through.
• White stretch marks (striae alba) appear where the blood vessels have receded, showing the fat beneath the dermal layer. This explains their silvery white appearance.

Stretch marks they are usually seen in regions of the body that are known to be very susceptible to rapid increase in girth. The dermal layer of the skin is stretched out, making it appear cracked and torn. Stretch marks are usually caused by fluctuations in weight. This is why stretch marks appear during pregnancy. They are also seen in people who work out, because of the development of muscle mass and become apparent in dieters who have lost a lot of weight.
