eli5: retinol for skin care increases cell turnover, but doesn’t increase cell cancer risk? ELI5!

If cell turnover is increased, I’d assume these types of products encourage cell apoptosis. I’d assume this is why I’ve read that, clinically, it may be able to ‘fight cancer’. 

But if cell turnover is increased, doesn’t this mean there’s more chances for a cell to exist which is cancerous? 

E.g. (albeit a poor example)

Normal cell turnover = 3 cells live and die per unit (“x”) amount of time. Meaning that per “x” unit of time, 3 cells existed. 

Retinol turnover = 3 cells live per x/2 amount of time, meaning that per “x” unit of time, 6 cells existed. 

So this is 6 chances for a cancerous cell to exist, rather than the original 3, for the same (given) amount of time? 

I’ve tried researching but it’s a scary topic and hard to ask this specific question! 

Thank you for any explanations!

While it’s true higher rate of cell turnover will increase the rate of deleterious mutations, vast majority of skin cancer is highly linked with UV exposure. Retinol is only used on a small part of the skin(ie face) so in theory while it may increase the rate of cancer by a tiny amount, without extra sun damage the risk is negligible.
