Erasing of stretch marks is a subject of significant concern for several women, especially those who have had children and are striving to regain their shapely figure and radiant skin tone. The team at Celtrixa stretch marks have done intensive research and tests to examine the cause for stretch marks, especially in pregnant women. The underlying tissues in the skin become stretched more than normal when a woman is carrying a baby, and this can sometimes by overwhelming on the skin. This is why stretch marks will form on the belly mainly, but women may also notice them on the breasts, since these organs grow significantly during pregnancy. Research shows that quite a few women actually start developing stretch marks well before pregnancy, during their puberty which perhaps expounds during pregnancy.
