Nobody likes stretch marks on their skin, be it red or white. They are harmless scarring marks on the skin that develop mainly when the body gains weight. They usually occur during pregnancy on the belly and commonly on the areas of body like breasts, thighs, buttocks and arms.
Another reason of these marks is bodybuilding and hormonal changes. With increased weight, the skin stretches rapidly causing a tear in the dermis, the middle layer of the skin. These marks appear reddish or purplish in the beginning when the skin stretched.
The red stretch marks
Red-coloured stretch marks are those fresh marks that you notice in the beginning. These marks show the blood vessels through, hence the red colour appears on the skin. If you take early precaution at this stage, these marks can heal fast by restoring collagen through various topical creams.
The white stretch marks
These marks are considered to be the most stubborn marks on the skin. Such scars have been on your body for a long time. These white stretch marks are not new and can't be healed with topical creams. They appear tiny on the skin. This is one of the reasons that there hasn't been any 'perfect cure' for white stretch marks till now.
