What is going on with my skin (and how do I stop it)?

[ChristmasWithBellsOn]

I have reasonably clear skin, slightly greasy, slightly enlarged pores, but not too bad.

But each time I go out in the cold, then come home to the warm, this happens... Serious blotchiness.

It only lasts the evening, I'm not even overly bothered by it, but it's weird.

The same sometimes happens if I have a hotter than normal shower.

If my skin looks shiny, it's because I've just applied night cream to try to temp it back to normal.

Hi OP, we're just bumping this one for you in the hope that someone will be able to help.

It looks like rosacea. I get it a little, you can get different creams that help it.
I think it helps if you treat it like sensitive skin and just keep well moisturised and use very genital cleansers etc.
Others may have better advice though.

Could it be rosacea, OP? I think that can be triggered by change of temperature (as well as by various other things). I've only just realised that I've probably got it. It's not as pronounced as yours, and it's there a bit all the time, but it gets much redder if I get hot or after alcohol and certain foods.

Cross-posted. I've just signed up for a trial of dermatica products, but I've seen other people recommend CeraVe too, which is available on Amazon.

Looks like you've aggravated the skin barrier and triggered rosacea.
As pp, Cerave is good, as is La Roche Posay Toleriane and I think they do one for rosacea (Roseliac, or something like that)
