Abstract
The photoprotective skincare segment is in high demand to meet consumer concerns on UV-induced skin damage, with a recent trend towards sunscreen alternatives with a natural origin. In this study, the use of natural ingredients, either from terrestrial or marine origin, in a panel of 444 sunscreen commercial formulations (2021) was analyzed. Ingredients from terrestrial organisms represent the large majority found in the analyzed sunscreen formulations (48%), whereas marine ingredients are present only in 13% of the analyzed products. A deeper analysis regarding the most prevalent families of ingredients from terrestrial and marine organisms used as top ingredients is also presented, as well as their mechanisms of action. This study provides an up-to-date overview of the sunscreen market regarding the use of natural ingredients, which is of relevance for scientists involved in the development of new sunscreens to identify opportunities for innovation.

Abstract
Objective: Exposure to ultraviolet (UV) light from the sun is known to accelerate the skin aging process and leads to significant alterations in skin biomechanics; however, the molecular mechanisms by which chronic UVB affects biomechanical properties of the skin have not been well described. Approach: A murine model for chronic UVB exposure was used to examine changes in epidermal barrier function, skin biomechanics, and miRNA expression as a result of UVB. Results: UVB irradiation caused skin to be weaker, less elastic, stiffer, and less pliable. Notably, these changes were not reversed after a 5-week period of recovery. Following UVB exposure, dermal collagen fibrils were significantly smaller in diameter and expression of the miR-34 family was significantly increased. Innovation: To our knowledge, this is the first study to concurrently examine alterations in skin function, miRNA expression, and tissue biomechanics in response to chronic UVB exposure. Conclusion: The data suggest that UVB alters miR-34 family expression in skin, in addition to dysregulating collagen structure with subsequent reductions in strength and elasticity. miRNAs may play a pivotal role in regulating extracellular matrix deposition and skin biomechanics following chronic UVB exposure, and thus may be a possible target for therapeutic development. However, additional studies are needed to directly probe the link between UVB exposure, miRNA production, and skin biomechanics.

Abstract
Ultraviolet (UV) irradiation is a potent inducer for skin photoaging. This paper investigated the anti-photoaging effects of the acetylated and amidated hexapeptide (AAH), originally identified from Spirulina platensis, in (Ultraviolet B) UVB-irradiated Human immortalized keratinocytes (Hacats) and mice. The results demonstrated that AAH had much lower toxicity on Hacats than the positive matrixyl (81.52% vs. 5.32%). Moreover, AAH reduced MDA content by 49%; increased SOD, CAT, and GSH-Px activities by 103%, 49%, and 116%, respectively; decreased MMP-1 and MMP-3 expressions by 27% and 29%, respectively, compared to UVB-irradiated mice. Employing isobaric tags for relative and absolute quantitation (iTRAQ)-based proteomics, 60 differential proteins were identified, and major metabolic pathways were determined. Network analysis indicated that these differential proteins were mapped into an interaction network composed of two core sub-networks. Collectively, AAH is protective against UVB-induced skin photoaging and has potential application in skin care cosmetics.

Abstract
Epigenetic repressor polycomb group (PcG) proteins are thought to serve a role in a number of cellular processes, including carcinogenesis, senescence, apoptosis and DNA repair. In the present study, long-wave ultraviolet A (UVA) was used to irradiate human skin fibroblasts (HSFs) and embryonic skin fibroblasts (ESFs) in order to simulate photoaging of the skin. The results of cell proliferation, apoptosis, hyaluronic acid (HA) content and reverse transcription-quantitative polymerase chain reaction assays revealed that the expression levels of genes encoding key PcG proteins (BMI-1 and EZH2) were altered. In addition, the expression levels of these genes were associated with the expression of enzymes that regulate HA synthesis. Furthermore, the expression levels of PcG proteins differed between HSFs and ESFs, suggesting that PcG proteins serve a role in altering HA synthesis during the UVA-induced fibroblast aging process. This signaling pathway may represent a novel molecular mechanism regulating the photoaging of the skin. The findings of the present study provide important insights into the underlying mechanisms of photoaging of the human skin. Further studies are required to clarify the molecular mechanisms underling skin aging and to identify targets for the clinical treatment of photoaging.

Abstract
Cellular senescence is now recognized as one of the nine hallmarks of ageing. Recent data show the involvement of senescent cells in tissue ageing and some age-related diseases. Skin represents an ideal model for the study of ageing. Indeed, skin ageing varies between individuals depending on their chronological age but also on their exposure to various exogenous factors (mainly ultraviolet rays). If senescence traits can be detected with ageing in the skin, the senescent phenotype varies among the various skin cell types. Moreover, the origin of cellular senescence in the skin is still unknown, and multiple origins are possible. This reflects the mosaic of skin ageing. Senescent cells can interfere with their microenvironment, either via the direct secretion of factors (the senescence-associated secretory phenotype) or via other methods of communication, such as extracellular vesicles. Knowledge regarding the impact of cellular senescence on skin ageing could be integrated into dermatology research, especially to limit the appearance of senescent cells after photo(chemo)therapy or in age-related skin diseases. Therapeutic approaches include the clearance of senescent cells via the use of senolytics or via the cooperation with the immune system.

Abstract
CONTEXT Schisandra chinensis (Turcz.) Baill. (Schisandraceae) fruit extract (SFE) has been reported to induce non-specific tissue protection against inflammation in vivo. However, the effects of SFE on Propionibacterium acnes-stimulated acne and UVB-irradiated photoageing have yet to be investigated. OBJECTIVE To systematically investigate the effects of SFE against P. acnes and photoageing in vitro. MATERIALS AND METHODS Qualitative and quantitative analyses of SFE were performed by HPLC. SFE concentrations from 2.5 to 50 μg/mL were tested. Specifically, ELISA was used to examine the levels of pro-inflammatory cytokines in THP-1 cells as well as of collagen I and matrix metalloproteinases-1 in HDF cells. The anti-bacterial effect of SFE was determined using the microdilution broth method. Glutathione and malondialdehyde levels were examined using the colorimetric and TBA methods, respectively. The degree of ageing was determined by cytochemical staining. RESULTS SFE significantly inhibited P. acnes growth (MIC 0.5 mg/mL) and 50 μg/mL of SFE suppressed the production of interleukin-1β, interleukin-8 and tumour necrosis factor α, by 59.67%, 62.69% and 68.30%, respectively, in P. acnes-stimulated THP-1 cells. Additionally, 10 μg/mL of SFE suppressed photoageing in UVB-exposed fibroblasts by decreasing metalloproteinase levels by 88.4%, inducing collagen by 58.4% and activating the anti-oxidant defence system, by limiting lipid peroxidation by 51.1% and increasing glutathione production by 34.1% (2.5 μg/mL SFE). DISCUSSION AND CONCLUSION These results indicated that SFE could significantly ameliorate the inflammatory state in P. acnes-stimulated THP-1 and UVB-irradiated HDF cells, suggesting its potential as a novel agent for acne therapy and photoageing prevention.

Abstract
Microsorum grossum (Polypodiaceae), locally called metuapua'a, is one of the most frequently used fern species in Polynesian traditional medicine. Fronds or rhizomes of this species are common ingredients of popular medicine recipes to cure various ailments. M. grossum frond and rhizome extracts contain, as their main bioactive components, phytoecdysteroids such as 20-hydroxyecdysone, known to have many interesting biological activities and considered to be adaptogenic compounds [1]. The skin-active effect of M. grossum extract was investigated in two ways on human dermal fibroblasts: a transcriptomic study with c-DNA array for gene expression modulation and a Stress Induced Premature Senescence (SIPS) test. The total extract of M. grossum up-regulates Heme Oxygenase 1 (HO1), an enzyme which protects cells from oxidative stress and which is responsible for skin photoimmunoprotection. The present paper also reports that premature senescence of human skin induced by repeated UV irradiations can be prevented by an ecdysteroid fraction of M. grossum. Our data indicate that extracts of M. grossum could protect skin against oxidative stresses and suggest that they could be used as innovative active cosmetic ingredients.

Abstract
Objective This study was aimed to evaluate the anti-photoaging effects of baicalin on Ultraviolet B (UVB)-induced photoaging in the dorsal skin of hairless mice and premature senescence in human dermal fibroblasts. Methods We established in vivo and in vitro photoaging models by repeated exposures to UVB irradiation. By HE staining, masson staining, immunohistostaing and real-time RT-PCR, we analyzed epidermal thickness, collagen expression and the mRNA and protein levels of type I collagen, type III collagen, interstitial collagenase (MMP-1 and MMP-3) in UVB exposed dorsal mice skin. The aging condition in human dermal fibroblasts was determined by senescence-associated β-galactosidase (SA-β-gal) staining. Cell viability was determined using the Cell Counting Kit-8 (CCK-8). The G1 phase cell growth arrest was analyzed by flow cytometry. The senescence-related protein levels of p16INK-4a, p21WAF-1, and p53 and protein levels of phosphorylated histone H2AX were estimated by Western blotting. Results Topically application of baicalin treatment reduced UVB-induced epidermal thickening of mouse skin and also result in an increase in the production of collagen I and III, and a decrease in the expression of MMP-1 and MMP-3. Compared with the UVB-irradiated group, we found that the irradiated fibroblasts additionally treated with baicalin demonstrated a decrease in the expression of SA-β-gal, a increase in the cell viability, a decrease in the G1 phase cell proportion, a downregulation in the level of senescence-associated and γ-H2AX proteins. However, Baicalin had no difference in the normal fibroblasts without UVB irradiation and long-term Baicalin incubation of UVB-SIPS fibroblasts gave no effects on the cell proliferation. Conclusions Taken together, these results suggest that baicalin significantly antagonizes photoaging induced by UVB in vivo and in vitro, indicating the potential of baicalin application for anti-photoaging treatment.

Abstract
This study was aimed to evaluate the anti-photoaging effects of Botulinum Toxin Type A (BoNTA) in Ultraviolet B-induced premature senescence (UVB-SIPS) of human dermal fibroblasts (HDFs) in vitro and the underlying mechanism. We established a stress-induced premature senescence model by repeated subcytotoxic exposures to Ultraviolet B (UVB) irradiation. The aging condition was determined by cytochemical staining of senescence-associated β-galactosidase (SA-β-gal). The tumor suppressor and senescence-associated protein levels of p16(INK-4a), p21(WAF-1), and p53 were estimated by Western blotting. The G1 phase cell growth arrest was analyzed by flow cytometry. The mRNA expressions of p16, p21, p53, COL1a1, COL3a1, MMP1, and MMP3 were determined by real-time PCR. The level of Col-1, Col-3, MMP-1, and MMP-3 were determined by ELISA. Compared with the UVB-irradiated group, we found that the irradiated fibroblasts additionally treated with BoNTA demonstrated a decrease in the expression of SA-β-gal, a decrease in the level of tumor suppressor and senescence-associated proteins, a decrease in the G1 phase cell proportion, an increase in the production of Col-1 and Col-3, and a decrease in the secretion of MMP-1 and MMP-3, in a dose-dependent manner. Taken together, these results indicate that BoNTA significantly antagonizes premature senescence induced by UVB in HDFs in vitro, therefore potential of intradermal BoNTA injection as anti-photoaging treatment still remains a question.

Abstract
Previous studies showed that several miRNAs can regulate pathways involved in UVB-induced premature senescence and response to ultraviolet irradiation. It has also been reported that miR-34c-5p may be involved in senescence-related mechanisms. We propose that miR-34c-5p may play a crucial role in senescence of normal human primary dermal fibroblasts. Here, we explored the roles of miR-34c-5p in UVB-induced premature senescence on dermal fibroblasts. MiR-34c-5p expression was increased in dermal fibroblasts after repeated subcytotoxic UVB treatments. Underexpression of miR-34c-5p in dermal fibroblasts led to a marked delay of many senescent phenotypes induced by repeated UVB treatments. Furthermore, underexpression of miR-34c-5p in dermal fibroblasts can antagonize the alteration of G1-arrested fibroblasts. Moreover, E2F3, which can inactivate p53 pathway and play a role in cell cycle progression, is a down-stream target of miR-34c-5p. Forced down-expression of miR-34c-5p decreased the expression of UVB-SIPS induced P21 and P53 at both mRNA and protein levels. Our data demonstrated that down-regulation of miR-34c-5p can protect human primary dermal fibroblasts from UVB-induced premature senescence via regulations of some senescence-related molecules.

Abstract
Skin is a model of choice in studies on aging. Indeed, skin aging can be modulated by internal and external factors, reflecting its complexity. Two types of skin aging have been identified: intrinsic, mainly genetically determined and extrinsic—also called "photo-aging"—resulting on the impact of environmental stress and more precisely of UV rays. Simplified in vitro models, based on cellular senescence, have been developed to study the relationship between UV and aging. These models vary on the cell type (fibroblasts or keratinocytes, normal or immortalized) and the type of UV used (UVA or UVB).

Abstract
We tested the activity of the marine nutraceutical CL-1222 added with a coenzyme Q10 (CoQ10)-lutein-selenium component (Celergen(®), Laboratoires-Dom, Switzerland) to protect human fibroblasts against ultraviolet A (UVA)-induced photoaging. Cells obtained from 22- to 39-year-old healthy donors were pretreated with CL-1222 before UV irradiation, as compared with same quantity of the CoQ10-lutein-selenium component. As compared to untreated control, UVA-irradiated samples exhibited a significant increase of secreted matrix metalloproteinase-1 (MMP-1) (p<0.001) with over four-fold MMP-1 upregulation (p<0.001). Samples treated with CL-1222, but not with the CoQ10-lutein-selenium component, showed a significant decrease of MMP-1 secretion (p<0.01) and expression decrease (>60%, p<0.01) with >54% elastase activity inhibition (p<0.01). This preliminary study shows that such marine nutraceuticals can significantly protect against UV-irradiation irrespective of the CoQ10-lutein-selenium component with a specific protective gene expression modulation amenable to novel clinical applications.

Abstract
We examined the intradermal delivery of a hydrophilic polyphenol chlorogenic acid by in vitro study using excised guinea pig dorsal skin and Yucatan micropig skin. Skin accumulation as well as the solubility of chlorogenic acid in aqueous vehicles was much greater than for other polyphenols such as quercetin and genistein. However, since enhancement of skin delivery seemed to be necessary to exhibit its protective effects against oxidative damage of skin, we examined the effects of microemulsions as vehicles. Using microemulsions consisting of 150 mM NaCl solution, isopropyl myristate, polyoxyethylene sorbitan monooleate (Tween 80) and ethanol, skin accumulation as well as solubility of chlorogenic acid further increased. Enhancement effect of an oil-in-water (o/w-type) microemulsion was greater than that of a water-in-oil (w/o-type) microemulsion possibly due to the greater increase in solubility. This finding was quite different from previous findings on relatively hydrophobic polyphenols such as quercetin and genistein. Pretreatment of guinea pig dorsal skin with chlorogenic acid containing microemulsion gel prevented erythema formation induced by UV irradiation. These findings indicate the potential use of hydrophilic chlorogenic acid with o/w-type microemulsion as a vehicle to protect skin against UV-induced oxidative damage.

Abstract
To improve the efficiency of the intradermal delivery of genistein and other two isoflavones (daidzein and biochanin A), we tried to clarify the usefulness of microemulsion by in vitro study on excised guinea pig dorsal skin and Yucatan micropig skin. Using microemulsion consisting of isopropyl myristate (IPM), 150 mM NaCl solution, Tween 80 and ethanol as a vehicle, the solubility of all the isoflavones markedly increased and significant amounts of isoflavones were delivered to the skin. The effect of water-in-oil (w/o)-type microemulsion D was larger than that of oil-in-water (o/w)-type microemulsion A. Among three isoflavones tested, the increase of genistein was most marked on both solubility and skin accumulation. Genistein retained in the skin significantly inhibited lipid peroxidation in vitro dose-dependently. Furthermore, pretreatment of guinea pig dorsal skin with genistein containing gel-like microemulsion D prevented UV irradiation-induced erythema formation. These findings indicate the potential use of w/o-type microemulsion for the delivery of genistein to protect skin against UV-induced oxidative damage.

Abstract
BACKGROUND Genistein, as an active compound of dietary antioxidants, has shown considerable promise as an effective agent against aging process. However, the effect of genistein on skin photoaging and the associated mechanism remain unclear. OBJECTIVE To delineate the effect of genistein on UVB-induced senescence in human dermal fibroblasts (HDFs) with emphasis on the mechanism of oxidative pathway regulated by p66Shc involved in the events. METHODS HDFs were induced to premature senescence by repetitive subcytotoxic doses of UVB irradiation. Cellular apoptosis and DNA cell cycle were analyzed using flow cytometry. Intracellular levels of superoxide dismutase (SOD) and malondialdehyde (MDA) were detected by ELISA. Mutation levels of two large deletions of mitochondrial DNA, 4977bp and 3895bp deletion, were determined by quantitative PCR. Western blot was applied to detect the expression and activation of p66Shc (the 66-kilodalton isoform of the growth factor adapter Shc) and FKHRL1 (a forkhead protein that is intimately linked with intracellular oxidation). RESULTS Strong activity of senescence-associated beta-galactosidase (SA-beta-gal), high percent of cell apoptosis as well as cell cycle arrest in G0/G1 phase, and increased intracellular oxidative stress were observed in HDFs irradiated by UVB. Genistein exerted dramatically protective effects on HDFs in a dose-dependent manner. Elevated copy numbers of large deletions in mitochondrial DNA were also inhibited by genistein. Down-regulation of total and phosphorylated p66Shc on Ser36, as well as FKHRL1 and its phosphorylation on Thr32, were observed after genistein treatment. CONCLUSION The results indicate that genistein protects UVB-induced senescence-like characteristics in HDFs via maintenance of antioxidant enzyme activities and modulation of mitochondrial oxidative stress through down-regulation of a p66Shc-dependent signaling pathway, which may provide potential prevention against skin aging and even photoaging.
