Hi Dear, Welcome to HCM. Understanding your concern. As per your query you have itching sensation on face while suffering from rosacea, Well rosacea is a common skin condition that causes redness in your face and often produces small, red, pus-filled bumps . There are hereditary , environmental factors and trigger factory that can cause rosacea temperature extremes , sunlight , stress, anger , corticosteroids, such as prednisone , drugs that dilate blood vessels . I would suggest you to avoid trigger factors if you know what start it , protect yourself from sun exposure , wash your face with cold water and take over the counter anti histamine like bendryl . You should not start medication after proper prescription. If condition doesn t get better then consult dermatologits for proper examination . Doctor may order skin test or elemination test . Doctor may prescribe steroid ointment , antibiotics or isotretinoin . Do not use any skin product except petroleum jelly . Hope your concern has been resolved. Get Well Soon. Best Wishes, Dr. Harry Maheshwari
