Topical sprout extract and UV erythema
Does applying sprout extract to skin change the redness response after UV exposure?
Human and animal · topical skin experiments

Key findings
Mean reduction in erythema response
In humans, post-UV erythema was 37.7% lower on average (p=0.025). Individual reductions ranged widely from 8.37% to 78.1%.
Response of cellular defense pathways
Responses of phase 2 protective enzymes in skin were examined to propose a cellular defense mechanism against UV damage.
Topical application trial
Results from applying extract directly to skin.
Study design
A sulforaphane-rich extract was applied to the skin of six healthy adults before exposure to several UV intensities. Animal experiments on skin inflammation and protective enzymes were also conducted.
