In an in vitro study, we have also shown that resveratrol treatment
blocked UVB-mediated activation of NF-jB pathway in the
normal human epidermal keratinocytes (NHEK), in a dose- as well
as time-dependent fashion. In a study done by Liu et al., it was
shown that resveratrol protects human HaCaT keratinocytes from
UVA-induced oxidative stress damage by downregulating Keap1
expression
