Rash/Pimples - Weather/Diet/Geography factors?

I moved Peru to Spain in Spring and over the last few months have started to have an outbreak of small spots across my face.It seems to be getting worse as winter is coming and flares up (cheeks-temples become red - spots are more defined) when I come in from the cold,however I was living in a part of Peru with similar cold so I'm not sure if this is the cause. I don't use make up and have been laying off any facial creams, but it doesn't seem to have solved anything. Any thoughts or advice?
