– Why does skin repair on your face when you get a scab, but not when you get acne?

In: Biology

I hope someone can explain this. My understanding is: It depends how deep it goes. If you take out the last few at the bottom of you skin, then they can’t grow back. That makes a scar.

Oh, it’s *trying* to heal. But acne isn’t one owie a year, it scabs over and it’s done… acne is an ongoing process where every goddamn time an individual wound starts healing, something else causes yet another wound (often in the same place). Some pores do make it to the scab stage and return to normal eventually— but others are stuck in a permanent cycle of partial healing and yet more destruction.

Acne occurs from the lower layers of your skin up, and consists of more than just the visible pimple. These lower layers of skin do not heal like the top layers. They form scar tissue.

A cut is usually on the top layers of your skin. Assuming the cut wasn’t very deep, only the top layers of your skin will be affected. They will heal completely, leaving no scar tissue.

Note that blood vessels are not under *all* the layers of your skin. capillaries extend quite deep into the skin (ie, come quite close to the surface). you can cut a capillary without going deep. Think of a shaving cut.
