When your body changes its shape stretch marks is something common. They usually occur during your pregnancy period. Commonly on your belly and on some body parts like breasts, thighs or buttocks etc. With weight changes, bodybuilding or hormonal changes. The skin stretches rapidly causing a tear in the dermis, the middle layer of the skin. This condition begins with an appearance of reddish or purplish marks. The marks appear as a band of parallel lines with different colours and texture. Mostly they are of two colour red and white. Now let us look at the difference between both of them:
The red stretch marks Red-coloured stretch marks are the ones that are just popping on your skin. These marks are fresh and only the beginning of the marks. Such scarring shows the blood vessels through, hence the colour red pops. At this stage, the marks can heal fast by restoring collagen through various topical creams.
The white stretch marks White scars have been on your body for a long time. These white or silverish coloured marks are the older ones. They cannot be treated with topical creams. The white marks are the most stubborn scarring on the skin, as they are tiny tears on the skin. This is one the reasons that there hasn't been any 'perfect cure' for white stretch marks till now.
