UVA1 Phototherapy in a national reference center:A 10-year systematical analysis

Introduction

UV A1 phototherapy (340–400 nm) has proven safe and effective for various skin conditions. However, limited published data make it challenging to establish individualized treatment protocols for many of these disorders. This study retrospectively analyzed the efficacy and tolerability of medium-dose UV A1 phototherapy (40-60 J/cm²) for various dermatological conditions.
