Is rosacea an allergy?
Although rosacea is not an allergy, various factors can aggravate its course. Spicy foods, alcohol and hot beverages are known to trigger flushing episodes. People with rosacea are often irritated by cosmetic products and soaps. Certain medications, for example, amiodarone, topical steroids, nicotinic acid and B vitamins, can induce flares of rosacea.
