Eczema cream put to the light test: will it cause skin reactions?
NCT ID NCT04361136
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage trial tested whether delgocitinib cream, a potential eczema treatment, makes skin more sensitive to light. Thirty-five healthy adults received a single application of the cream and a placebo on different skin spots, then were exposed to UV light. Researchers checked for redness, blisters, or other reactions to see if the cream could cause phototoxicity.
