October 2007 in “Proceedings of the National Academy of Sciences of the United States of America” This study found that sulforaphane-rich broccoli sprout extracts reduced UV-induced erythema by 37.7% in humans, suggesting a protective strategy against UVR damage.
August 2026 in “Molecules” This study found that Eucommia ulmoides bark extract shows potential antioxidant and hair follicle-support properties in vitro and in vivo, but further validation is needed to confirm these effects.
November 2022 in “Journal of Investigative Dermatology” This study found that apocynin restored collagen production, reduced DNA damage and senescence, and protected skin stem cells from aging in UVB-exposed human keratinocytes.
July 2022 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that apocynin restored COL17A1 expression in human keratinocytes and reduced UVB-induced cellular senescence, DNA damage, and cell cycle arrest.
