Well, sun can activate rosacea , but rosacea usually "attacks" nose, chin, sometimes eyelids and sometimes cheeks , but i am almost sure that you don't have it - I don't know why

, just intuition I guess ; ) ! You might be just extra sensitive to the sun, and stress definitely causes our capillaries to widen and we get "nice glow"

)), heat has same effect

. You are just a "blushing bride" baby -doll ; ), that is cute !!!!! Do you know that some people (like me) blush on different parts of a body in those situations ???? I blush on my neck and chest area - imagine that embarrassment !!! Once doctor called his colleagues to "see rare example", I was at OBGYN, office,mind you !!! Doctors are sometimes really idiots!
