well sometimes i go like an hour without thinking about it relying on eucerin and the steroid cream i put on the night before i am able to have some comfort, i honestly do not think about it until i touch my face and can feel the heat coming off or when it starts to tingle, now just because my skin is hot and its tingling does not always mean i am flushed it just makes me feel like i am. The worst part is when you are walking around and feel an urge to find a mirror just to verify that you are or are not flushed.
