Abstract: Pearl oysters have been extensively utilized in pearl production; however, most pearl oyster shells are discarded as industrial waste. In a previous study, we demonstrated that the intraperitoneal administration of pearl oyster shell-derived nacre extract (NE) prevented d-galactose-induced brain and skin aging. In this study, we examined the anti-aging effects of orally administered NE in senescence-accelerated mice (SAMP8). Feeding SAMP8 mice NE prevented the development of aging-related characteristics, such as coarse and dull hair, which are commonly observed in aged mice. Additionally, the NE mitigated muscle aging in SAMP8 mice, such as a decline in grip strength. Histological analysis of skeletal muscle revealed that the NE suppressed the expression of aging markers, cyclin-dependent kinase inhibitor 2A (p16) and cyclin-dependent kinase inhibitor 1 (p21), and increased the expression of sirtuin1 and peroxisome proliferator-activated receptor gamma coactivator 1 (PGC1)- α, which are involved in muscle synthesis. These findings suggest that the oral administration of NE suppresses skeletal muscle aging. Moreover, NE administration suppressed skin aging, including a decline in water content. Interestingly, oral administration of NE significantly extended the lifespan of SAMP8 mice, suggesting that its effectiveness as an anti-aging agent of various tissues including skeletal muscle, skin, and adipose tissue.

Abstract: For centuries, mushrooms have been used as a component of skincare formulations. Environmental stresses and a modern lifestyle expose the skin to accelerated aging. To slow down this process, natural anti-aging skincare ingredients are being sought. In this review, 52 scientific publications about the effects of chemical compounds extracted from the fruiting bodies of macrofungi on skin cells were selected. The effects of extracts from nine species that are tested for anti-aging effects have been described. According to available literature data, macrofungi contain many polysaccharides, phenolic compounds, polysaccharide peptides, free amino acids, sterols, proteins, glycosides, triterpenes, alkaloids, which can have an anti-aging effect on the skin by acting as antioxidants, photoprotective, skin whitening, moisturizing, anti-inflammatory and stabilizing collagen, elastin and hyaluronic acid levels in the skin.

Purpose: The study aimed to investigate in vitro anti-aging activities of 29 Dendrobium spp. and develop and characterize microemulsions (MEs) for topical application.

Methods: Antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), H2O2 scavenging, and ferric reducing antioxidant power (FRAP) assays. The anti-collagenase (MMP-1 and MMP-2) and anti-elastase activities were also evaluated.

Cytotoxicity and human intracellular reactive oxygen species (ROS) levels were determined using resazurin reduction and 2′,7′- dichlorofluorescin diacetate (DCFDA) assays, respectively. D. kentrophyllum extract-loaded microemulsion (DKME) was then prepared and optimized. The stability of DKME was studied using a heating-cooling cycle.

Results: D. kentrophyllum appeared to be the best candidate anti-aging agent because of its antioxidant, anti-collagenase, and antielastase activities. The extract was safe for human skin cells at a concentration of 6.25–100 μg/mL. It also decreased the intracellular ROS-induced ultraviolet B (UVB) irradiation compared to that in the control. DKME comprising Tween 80:ethanol (5:1), water, and isononyl isononanoate showed a suitable appearance, droplet size, polydisperse index, zeta potential, pH, and viscosity. This formulation demonstrated desirable physical and chemical stability, with non-cytotoxic effects.

Conclusion: DKME is considered a promising anti-aging product. However, an in vivo study of this optimized formulation might be evaluated in further study for anti-aging purposes.

Abstract: Isoflavones are found in numerous plant species within the Leguminosae family; however, soy isoflavones are particularly significant in practice and have been extensively studied in recent years. The health-promoting potential of orally administered soy isoflavones is widely documented in the scientific literature, and many review articles have been developed to highlight their significance. However, it should be noted that soy-isoflavone-rich extracts and isolated soy isoflavones, such as genistein and daidzein, are also often applied topically as ingredients in many formulations, including face creams, tonics, and emulsions. New delivery systems are continuously being developed to enhance the skin permeability of isoflavones, thus improving their efficacy. In this context, their direct activity on skin cells is an important aspect of scientific research. The anti-inflammatory, protective, and antioxidant properties of isoflavones and soy extracts make them promising cosmetic ingredients with anti-aging potential because inflammation and the accumulation of reactive oxygen species (ROS) can lead to structural and functional changes in skin cells, accelerating the aging process. This review provides an overview of research on the impact of the application of soy isoflavone extract and soy-derived isoflavones on skin cells, with a focus on the documented molecular mechanisms underlying their effects. This study aims to offer essential insights to aid in the development of functional cosmetics and future clinical applications.

Abstract: Panax ginseng (Korean ginseng) is renowned for its health-promoting properties, attributed to its bioactive compounds, including saponins, polyphenols, and polysaccharides, which possess both antioxidant and anti-aging activities. This study investigated the anti-aging and antiinflammatory effects of compounds isolated from the hot water extract of fresh P. ginseng roots, evaluating their resistance to TNF-α/IFN-γ-induced skin cell damage. Among 14 compounds, ginsenoside Rf (compound 2) showed significant multi-target effects. In NHDFs, ginsenoside Rf and others effectively reduced intracellular ROS, demonstrating strong antioxidant properties. Additionally, they inhibited MMP-1 expression, a key enzyme in collagen degradation, and promoted pro-collagen Type I synthesis, countering the negative effects of TNF-α and supporting skin health. Further analysis showed that ginsenoside Rf reduced the secretion of inflammatory cytokines like IL-1β and IL-6, exhibiting anti-inflammatory effects. It also promoted the expression of crucial skin barrier proteins, including LOR, AQP3, FLG, and KRT1 in TNF-α/IFN-γ-stimulated NHEKs, enhancing skin hydration and structural integrity. These results suggest that compounds from P. ginseng roots, especially ginsenoside Rf, hold promise as skincare agents targeting skin aging and inflammation. Future research should further explore their mechanisms and optimize their applications in dermatological treatments.
