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.
