things like spicy food, coffee & alcohol make it worse. I've been drinking lemon juice, apple cidar vinegar & hot water every morning to try to control mine. Sometimes it works, other times it doesn't. I found only getting pg helped to clear it up. Drinking lots of water & putting cold packs on after exercise may also help. I'm also trying to go chemical free with skin care & makeup. I did see a dermatologist - she recommended Cetaphil (from the chemists). Healthy eating should help to clear it up too.
