Eli5..if cell turnover occurs every 28-50 days…why do scars/hyperpigmentation remain,

1.02K views

Particularly rolling acne scars and hyperpigmentation on the face.

I understand why deep scars/tattoos remain.

However, thought shallow scars and light sun spots would fad with a few months of cell turnover?

There are a lot of complex reasons and I’m sure someone will elaborate on them somewhere down the thread, but the easiest explanation is those cells replicate too.

All of the cells that make up your scars, freckles, birthmarks, etc. are also replicating exactly (more or less) how they are, which means that your weird mole is going to follow you around for your whole life, baring extraneous circumstances
