if skin can regenerate and heal itself albeit slowly, why can’t stretch marks and scars go back to normal?
In: Biology
When your skin regenerates over time it’s replacing cells with other cells in a working network.
When there is a cut or tear in the skin, it goes into “PATCH THE HOLE MODE” and stuffs the opening with a diffrent type of cell to close it ASAP. Because lots of nasty stuff can get in via an opening. That stuff it uses to plug the hole is diffrent from normal skin, it doesn’t sweat or grow hair either for the same reason.
