Summary Solar urticaria (SU) is an uncommon photodermatosis that presents with sensitivity to ultraviolet (UV) or visible light which triggers urticarial lesions. Treatment of SU is a challenge and usually involves antihistamines and photoprotection as a first‐line treatment. Phototherapy regimens are recommended if these first‐line treatments fail to control the disease. Induction of tolerance by phototherapy (UV hardening) has been commonly described as a treatment modality. UVA1 has deeper penetration to the dermis than UVA or NB‐UVB; its use in SU has not been previously reported. We present 3 patients with SU who were successfully treated with UVA1.
