Hello. Thank you for your question.
In general, I counsel patients about things they can do to avoid redness, skin sensitivity, flushing, and dry skin that don't involve medications. For milder cases, this can be sufficiency
First, patients should avoid spicy foods, alcohol, stress, sunlight, and extreme temperatures as these make flushing worse.
In regards to skin care, patients should keep their skin moisturized with emolients. These are available over the counter (i.e. Eucerin, etc).
