Your first step towards balancing your skin is to avoid or minimize sensitizing factors - things that trigger and aggravate sensitivity.
However, in case with coffee, quite the opposite effect is achieved by topical application of caffeine. It produces anti-inflammatory effect and was found to actually relieve skin redness.
Drink more water, eat more fruit and vegetables – vitamins and fiber will help to keep your skin healthy. There is no need to go into extremes, but if your sensitivity is really bad, you may consider excluding histamine containing foods: such as bananas, spinach, peas, cheese, shellfish, tinned tuna, chocolate, wine, cheese, citrus fruits, strawberries, tomatoes etc. Histamine containing foods trigger allergic reactions.
