Red upper arms

[Rox19]

Hello
I have pale skin and the tops of my arms always seem to be red. Whether I am hot cold drinking or not etc
It has been like this ever since I can remember, I'm now 31 but wondering if it's ketosis Polaris.
Has anyone else had this and is there a cream that will get rid of it?

Just dreading summer and the usual comments on it.

Thanks x

I have it. I've only just discovered that it is a 'thing' and it has a name (thanks to MN). I'm using an acid toner and Flexitol heel balm (again thanks to MN). 5 days in I see an improvement already.
