A randomized controlled trial has found that narrowband and broadband ultraviolet B (UVB) phototherapy offer similar efficacy in treating atopic dermatitis, though narrowband UVB may be better tolerated. The study, published in the Journal of the American Academy of Dermatology, compared the two treatments in patients with moderate to severe atopic dermatitis.
Researchers reported that both types of UVB phototherapy led to significant improvements in eczema severity scores, with no statistically significant difference between the two. However, narrowband UVB was associated with fewer side effects, such as erythema and burning, making it a potentially more tolerable option for patients.
The findings suggest that clinicians can consider either narrowband or broadband UVB phototherapy for atopic dermatitis, depending on patient tolerance and treatment goals. Further research is needed to confirm long-term outcomes and optimal treatment protocols.
