Skin allergy is a very common skin disease, mainly caused by exposure to certain allergens, resulting in corresponding skin symptoms. After suffering from skin allergies, it is definitely not advisable to drink alcohol. Alcohol is considered an irritant food, which may worsen the symptoms of skin allergies. In addition to not drinking alcohol, other spicy and irritating foods should also be avoided, such as not smoking and not eating stimulating foods like onions, ginger, and garlic.
