The study evaluates black ginseng extract's effects on collagen synthesis and UV-induced skin aging in fibroblasts, suggesting its skincare potential.
Chronic ultraviolet (UV) exposure disrupts dermal collagen homeostasis and accelerates skin aging. This study evaluated the protective effects of black ginseng extract (BGE) against UV-induced photoaging in human dermal fibroblasts. BGE restored collagen-related markers, including COL5A1 and COL7A1, improved fibroblast proliferative capacity, and reduced senescence-associated changes under UV stress. Data-independent acquisition (DIA) proteomics identified broad pathway modulation by BGE, involving extracellular matrix remodeling, chromatin organization, and stress-response processes. To validate genome maintenance-related signals highlighted by proteomics, qPCR showed that BGE increased telomere/replication-associated genes compared with the UV group, including POT1 (2.29-fold) and ORC1 (6.70-fold). In addition, comet assay imaging indicated reduced UV-associated DNA damage features following BGE treatment. Overall, these findings indicate that BGE mitigates UV-induced photoaging phenotypes in fibroblasts, with collagen-related recovery and multi-level protective responses, supporting its potential as a natural bioactive ingredient for anti-photoaging skincare applications.
