Dealing with a persistent facial rash can be very frustrating, but you are taking all the right steps. Since your skin is sensitive and your IgE levels are elevated, allergies or eczema may play a role. The pending ANA and LE tests are helpful tools to rule out autoimmune conditions. Because you have used topical steroids and antibiotics before, it is important to avoid restarting them without your doctor's guidance, as steroids can sometimes worsen facial rashes over time. For now, stick to a very gentle, fragrance-free cleanser and moisturizer. Please share your test results with your dermatologist so they can create a safe, targeted treatment plan for you.
