Skin allergy treatment may depend on the type of allergy you have and what’s causing your reaction. The dermatologist may recommend topical ointments to ease the redness and itching and antihistamines to reduce swelling and inflammation. With advances in medicine, our dermatologists can now offer medications specifically designed to treat moderate and severe cases of atopic dermatitis. The doctor may conduct allergy testing to identify the allergen if you’re not able to pinpoint the specific cause. Once you know what your allergen is, avoid contact or ingestion to prevent further breakouts. The dermatologist may also recommend you take measures to protect your skin from the sun, especially during a reaction, to reduce further irritation.
