With the advancement of biotechnology in the marine industry, an increasing utilization of marine ingredients in skincare products has been observed in recent years. Encapsulating Artemia franciscana extract and its derivatives in a novel phospholipid vesicle called hyalurosome presents innovative strategies for drug delivery systems and anti-aging products. In this study, we developed nano hyalurosomes containing Artemia franciscana active components. Partially purification of proteins in the Artemia franciscana extract was performed using ion exchange chromatography, specifically targeting Hsp40 and Artemin. The physicochemical properties of the hyalurosomes were characterized, revealing nanoparticle sizes ranging from 100 to 130 nm, zeta potential between −57 and −41.2 mV. The biological compatibility of the fabricated hyalurosomes was tested in vitro on mice fibroblast cells. Results indicated that formulations containing hyalurosomes exhibited no cytotoxicity. In-vivo studies employing H&E and Mason’s trichrome staining demonstrated an increase in the dermal layer of the skin on male mice and collagen production following treatment with different formulations containing hyalurosomes. Therefore, these formulations are considered promising candidates for anti-aging effects. Stability study at 4 °C for 60 days validated by FE-SEM imaging. In conclusion, hyalurosomes fabricated with Artemia franciscana extract and its diverse active molecules successfully achieved enhanced loading and penetration into the deeper layers of the skin, and it can be a suitable candidate for the treatment of skin aging and rejuvenation.

Abstract

Main conclusion This review highlights the potential of aromatic plants as natural antioxidants in cosmeceuticals to combat skin aging and promote health and rejuvenation.

Abstract Aromatic plant extracts, essential oils, or their phytoconstituents have a long history of use in skincare, dating back centuries. Currently, these plant-based sources are extensively researched and utilized in the cosmeceutical industry to formulate products that enhance skin health and promote a youthful appearance. These plants’ diverse bioactivities and sensory properties make them ideal ingredients for developing anti-aging agents recommended for maintaining healthy skin through self-care routines, offering a natural alternative to synthetic products. Reactive oxygen species (ROS) accumulation in the dermis, attributed to intrinsic and extrinsic aging factors, particularly prolonged sun exposure, is identified as the primary cause of skin aging. Plant extracts enriched with antioxidant compounds including favonoids, phenolics, tannins, stilbenes, terpenes, and steroids, are fundamental to counteract ROS-induced oxidative stress. Noteworthy effects observed from the use of these natural sources include photoprotective, senolytic, anti-infammatory, anti-wrinkle, anti-acne, and antityrosinase activities, encompassing benefits like photoprotection, wound healing, skin whitening, anti-pigmentation, tissue regeneration, among others. This review highlights several globally distributed aromatic plant species renowned for their benefits for skin, including Foeniculum vulgare Mill. (Apiaceae), Calendula ofcinalis L. and Matricaria chamomilla L. (Asteraceae), Thymus vulgaris L. (Lamiaceae), Litsea cubeba (Lour.) Pers. (Lauraceae), Althaea ofcinalis L. (Malvaceae), Malaleuca alternifolia (Maiden y Betche) Cheel (Myrtaceae), Cymbopogon citratus (DC.) Stapf (Poaceae), Rubus idaeus L. (Rosaceae), and Citrus sinensis L. Osbeck (Rutaceae), emphasizing their potential in skincare formulations and their role in promoting health and rejuvenation.

Abstract

Skin represents the main barrier against the external environment, but also plays a role in human relations, as one of the prime determinants of beauty, resulting in a high consumer demand for skincare-related pharmaceutical products. Given the importance of skin aging in both medical and social spheres, the present research aims to characterize microscopic changes in human skin composition due to intrinsic aging (as opposed to aging infuenced by external factors) via histological analysis of a photoprotected body region. Samples from 25 autopsies were taken from the periumbilical area and classifed into four age groups: group 1 (0–12 years), group 2 (13–25 years), group 3 (26–54 years), and group 4 (≥55 years). Diferent traditional histological (hematoxylin–eosin, Masson’s trichrome, orcein, toluidine, Alcian blue, and Feulgen reaction) and immunohistochemical (CK20, CD1a, Ki67, and CD31) stains were performed. A total of 1879 images photographed with a Leica DM3000 optical microscope were morphometrically analyzed using Image ProPlus 7.0 for further statistical analysis with GraphPad 9.0. Our results showed a reduction in epidermis thickness, interdigitation and mitotic indexes, while melanocyte count was raised. Papillary but not reticular dermis showed increased thickness with aging. Specifcally, in the papillary layer mast cells and glycosaminoglycans were expanded, whereas the reticular dermis displayed a diminution in glycosaminoglycans and elastic fbers. Moreover, total cellularity and vascularization of both dermises were diminished with aging. This morphometric analysis of photoprotected areas reveals that intrinsic aging signifcantly infuences human skin composition. This study paves the way for further research into the molecular basis underpinning these alterations, and into potential antiaging strategies.

Purpose: To report the outcomes of a novel microwave heating device (Blepha EyeBag®) used serially for the treatment of meibomian gland dysfunction (MGD).

Patients and Methods: This prospective single center study was conducted at University Magna Graecia of Catanzaro. Patients were instructed to apply the compress twice daily for 15 days and once per day every two days, as reported in the package insert. Outcome measures were i) ocular surface disease index (OSDI) score, ii) tear meniscus height (TMH), iii) non-invasive keratograph break-up time (NIKBUT) (first and average), iv) meiboscore, v) bulbar redness. Evaluations were performed at baseline (T0) after 15 days (T1) and after 45 days of therapy (T2).

Results: Overall, 19 patients with MGD (8 males, 11 females; mean age 64.58 ± 9.72 years) were included. The mean value of OSDI score showed a significant decrease from 28.16 ± 17.46 at T0 to 13.69 ± 7.62 at T2 (p=0.008). The mean value of NIKBUT first significantly increased from 6.67 ± 3.51 seconds (s) at T0 to 10.46 ± 4.64 at T2 (p=0.0121); in parallel, the mean value of NIKBUT average increased significantly from 11.09 ± 4.15 s at T0 to 14.95 ± 4.85 at T2 (p=0.0049). No significant differences were detected at each time point for bulbar redness, meiboscore and TMH. Throughout the entire study, no adverse events were recorded.

Conclusion: The microwave-heated eye bag treatment is both safe and effective for treatment of MGD, being able to significantly ameliorate both patient-reported symptoms and tear film stability.
