ABSTRACT

Aging is a natural process that occurs in all living organisms. Particularly, the skin embodies aging since it serves as a barrier between the body and its surroundings. Previously, we reported the wound healing effect of Launaea procumbens and identified compounds therein. The study aims to explore the skin anti-aging properties of the plant extract. To that effect, the antioxidant potential of L. procumbens methanolic extract (LPM) was assessed using two complementary DPPH and FRAP assays. The enzyme inhibitory effect of the extract on collagenase, elastase, hyaluronidase, and tyrosinase was evaluated to assess the direct skin anti-aging effects. Similarly, the anti-inflammatory activity was evaluated to explore the indirect anti-aging effects via the assessment of extract inhibitory effects on cyclooxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX). In addition, ADMET and molecular docking studies were performed to explore the interaction mechanisms of identified compounds in LPM with target enzymes. LPM demonstrated significant antioxidant activity in DPPH (IC50 = 29.08 µg/mL) and FRAP (1214.67 µM FeSO4/g extract) assays. Plant extract showed significant inhibition of collagenase, elastase, hyaluronidase, and tyrosinase (IC50 = 52.68, 43.76, 31.031, and 37.13 µg/mL, respectively). The extract demonstrated significant COX-2 and 5-LOX inhibition capacity with IC50 values of 8.635 and 10.851 µg/mL, respectively. The molecular docking study revealed the high potential of the identified compounds to bind to the active sites of enzymes crucially involved in the skin aging process. ADMET analysis of the compounds revealed their good absorption, distribution, and metabolism profiles, and they were found to be safe as well. Study findings suggest L. procumbens as a promising source for the development of natural skin anti-aging and anti oxidant compounds. This, in turn, may facilitate its incorporation into cosmetic formulations after further investigation.

ABSTRACT

Background: The 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.

Aim: To discover natural extracts that stimulate collagen production.

Methods: We 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.

Results: PathwayStudio 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 56days, measured by the DUB SkinScanner.

Conclusions: These 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.
