Layers of the Skin

Layers of the Skin

Stretch marks are a form of skin scarring which happens mainly during the time of fast growth and the stretching of a person’s skin. Common periods in one’s life are puberty and pregnancy. Hormonal changes go along with pregnancy and puberty and these changes take big influence in the development of stretch marks during these periods. So a change in our hormone system is the main cause for stretch marks.

Where do Stretch Marks Appear

Stretch marks are found anywhere on the body where a certain amount of fat is stored. Hips, abdomen, breasts or the upper part of the arms are common places for the development of stretch marks.

Signs and Symptoms of Stretch Marks

People recognize the development at first as a thin purple or darker red line which slowly fades out and leaves a narrow channel which feels soft when touching the affected area.

Causes of Stretch Marks

Caused are those lines by tearing the dermis. The Dermis is the middle layer of your skin and connects the subcutaneous tissue and the epidermis (the outer layer of the skin). When the dermis gets torn it can diminish which causes the epidermis to occupy that spare and the first symptoms of stretch marks will be visible. The most important components of the dermis are collagen and elastin.

Collagen is a protein which can be found all over the human body and is the most important component for connective tissues.  For that reason almost all skin-care creams include collagen as their main ingredient.
