April 2020 in “Oxidative Medicine and Cellular Longevity” This study provides evidence that Fernblock® upregulates antioxidant pathways in cultured keratinocytes, potentially protecting against damage from fine pollutant particles.
April 2026 in “Journal of Cosmetic Dermatology” This study found that exosomes derived from human umbilical cord mesenchymal stem cells helped preserve melanocyte function and mitigate stress-induced hair depigmentation in mice by activating the Nrf2-ARE antioxidant pathway under acute neurogenic oxidative stress.
October 2025 in “Phytomedicine” This study demonstrates that Bazi Bushen capsules may have therapeutic potential against skin photoaging in mice by enhancing NRF2 expression and targeting the KEAP1-NRF2 pathway.
