Striae (also called 'welts' or 'stretch marks') are linear parallel lines of the epidermis and dermis. These lines ('scars') in the skin are atrophic. An atrophic 'scar' occurs when the healing process is disrupted and insufficient new connecting fibers are formed. In principle, they may feel flat and smooth and be pink in color. After months or years, the pink color disappears and they turn white.
Treatment of stretch marks
To reduce stretch marks, it is important to check what the expectation pattern is. Just like scars, stretch marks cannot disappear completely. The treatment itself is aimed at making the color differences less noticeable and also strengthening the connective tissue. In the case of skin therapeutic treatments, these must be carried out several times, or in a course of treatment.
