Stretch marks are a kind of marks on the skin, which look like irregular lines, caused by the breakdown of the collagen, elastin and reticulin fibers that make up the dermis.
In the beginning, when they appear, they appear as reddish or violet color marks and with the passage of time they acquire a pearly whitish tone and a texture different from the rest of the skin, this being the phase in which it is much more complicated to eliminate them completely.
Although they can appear in various parts of the body, there are areas that are more vulnerable to stretch the elastic fibers of the skin than others, and these are the breasts, abdomen, hips, buttocks, thighs, knees and arms.
