Phytoestrogens as Natural Anti-Aging Solutions for Enhanced Collagen Synthesis in Skin.
Article in Journal of cosmetic dermatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe dermal extracellular matrix (ECM) is a dynamic scaffold composed mainly of proteins, with collagen as the key structural component providing resilience and support to the skin. Post-menopause, declining estrogen levels lead to a significant reduction in skin health, notably a 30% decrease in collagen types I and III within 5 years.
aimTo discover natural extracts that stimulate collagen production.
methodsWe utilized PathwayStudio to analyze protein-protein interactions and identify regulators of essential collagen types. Our study assessed Glycyrrhiza uralensis extract's ability to boost collagen production and enhance dermal density both in vitro and in vivo.
resultsPathwayStudio analysis highlighted phytoestrogens including glycyrrhizin, isoliquiritigenin, liquiritigenin, liquiritin, and glabrol, as potential candidates. Liquorice rhizome (G. uralensis), used in traditional Chinese medicine, is rich in phytoestrogens like liquiritigenin. The G. uralensis extract increased collagen I and III gene expression and pro-collagen I protein levels in human dermal fibroblasts and inhibited UVB and pollution-induced matrix metalloproteinase-1 (MMP1) production. In an in vivo study, a topical formulation containing the extract significantly improved dermal density after 56 days, measured by the DUB SkinScanner.
conclusionsThese findings suggest G. uralensis extract as a promising agent for enhancing collagen production and skin health, particularly in postmenopausal women. Further research is needed to explore its mechanisms and long-term effects.
