Stretch marks themselves are growth swelling marks, also called growth shrinkage marks. It is completely normal to have a distinct bump when you touch them with your hands. These stretch marks form because the body’s skin does not grow as fast as the body’s abdomen grows, resulting in splitting marks that can appear red or white. Most stretch marks do not hurt or itch, but if they appear too quickly they may be mildly itchy. The condition is a result of the tissue dividing process showing microcellular proliferation too slowly, which causes depressional changes, so it is completely normal to feel bumpy. If you want to remove stretch marks, you can choose to use topical medications or physical means to improve them. Topical medications can be applied with humanoid collagen repair silicone gel and treated with mucopolysaccharide polysulfate cream, but the effect is slow, and physical means can be treated with CO2 fractional laser.
