They’re available in different strengths, with the potency levels ranging from very potent (Class 1) to least potent (Class 7).Immunosuppressants — like their name suggests — suppress the immune system more broadly, tamping down the inflammation that triggers symptoms like itching and irritation.Phototherapy, or light therapy, uses different wavelengths of UV light to treat atopic dermatitis.
