if skin can regenerate and heal itself albeit slowly, why can’t stretch marks and scars go back to normal?
In: Biology
Scars are not exactly skin. After serious injury or burn, the wound is covered with blood clot, and starts to heal. Over time, wounded tissue morphs into collagen fibres – and it has different texture and density. By the way, if you heard about old wounds reopening that ships crews experienced in long voyages – this is because of scurvy. Malnutrition and lack of vitamins causes scurvy and one of the major effects of scurvy is that body can no longer produce collagen. As a result, a living body starts to disintegrate. Eat your vitamins, folks.
