yea I can relate...If the temperature changes drastically from cold to hot or if I'm in a hot room, my cheeks go red and flush (I can definilty feel them burning). Or if i think about it too much i become embarrassed and they go redder. It only happens on my cheeks however. Yours could be pre-rosacea...I'm just a blusher naturally I guess. I'd change this problem before i'd change having acne, thats how much I hate it. But sometimes I can control it (epecially when i'm cold, i'm guarenteed not to blush).
This is what you can do:
1. You can go to a derm. and see if they think IPL's would work for you. This is "intense pulsed light", which helps rosacea sufferers (it kills the dilated blood vessels and capillaries). I've had six done, and it smoothed my skin and helped a little with perm. redness and flushing but the bad part about it is that its no cure. My redness came back because the capillaries grow back and the price is very expensive ($300-$500 a treatment).
2. You can go to your regular doctor and get a perscription for meds that are for people with high-blood pressure such as Propanolol, Nadolol (which i use, only really in stressful situations). These help stop the blood from rushing to your face.
3. You can try to train yourself not to go red (which is really hard and most times i can never do it..lol)
4. Try to conceal it with makeup
5. Drink plenty of cold water to keep yourself cool.
Hope this helps
