Abstract
In this study, the formation of protein microspheres through lysosomal enzyme-assisted biomineralized crystallization was demonstrated. Spherical micro-sized hybrid CaCO3 constructs were synthesized and characterized using field-emission scanning electron microscopy equipped with energy-dispersive X-ray spectroscopy, X-ray diffraction, Fourier-transform infrared spectroscopy, and particle size analysis. Additionally, parameters such as the Brunauer-Emmett-Teller surface area and single-point total pore volume, and adsorption/desorption analysis were used to investigate the mesoporous properties, which are advantageous for lysosomal enzyme (LE) loading. A LE can be used as an organic template, not only as a morphological controller but also for entrapping LE during the crystallization pathway. The hybrid protein microspheres accommodated 2.3 mg of LE with a 57% encapsulation efficiency and 5.1 wt% loading. The peroxidase activity of the microspheres was calculated and found to be approximately 0.0238 mM-1 min-1. pH-responsive release of the LE from CaCO3 was observed, suggesting potential biomedical and cosmetic applications in acidic environments. The hybrid LE microsphere treatment significantly alleviated melanin production in a dose-dependent manner and further downregulated the mRNA expression of MITF, tyrosinase, TYRP-1, and TYRP-2. These results indicate skin-whitening effects by inhibiting melanin without inducing cytotoxicity. The data provide the first evidence of the potential use of a LE for obtaining hybrid minerals and the effectiveness of biomineralization-based sustainable delivery of enzyme-based vehicles based on organelle-extract-assisted biomineralization.

Repetitive Bathing and Skin Poultice with Hydrogen-Rich Water Improve Wrinkles and Blotches Together with Modulation of Skin Oiliness and Moisture. HYDROGEN 2022.

Abstract
Hydrogen-rich warm water (HW) has not been verified yet for skin anti-aging effects. Daily 10 min HW (dissolved hydrogen: 338–682 μg/mL, 41 °C) bathing and skin poultice with HW-impregnated towels for 11–61 days were demonstrated to improve wrinkle degrees (29 skin-loci) from 3.14 ± 0.52 to 1.52 ± 0.74 (p < 0.001) and blotch degrees (23 loci) from 3.48 ± 0.67 to 1.74 ± 0.86 (p < 0.001) in five healthy subjects (49–66 years old), by densito-/planimetrically evaluating with an Image-J software, and ranked into six hierarchies (0, 1–5). Meanwhile, skin oiliness was evaluated to increase for the oil-poor skins, but inversely decrease for excessively oily skins, suggesting the HW’s function as skin-oiliness modulation, with an appreciably negative correlation in prior oiliness contents versus change after HW application (r = −0.345, 23 loci). Skin moisture increased upon HW application, with a negative correlation (r = −0.090, 23 loci) in prior moisture contents versus post-HW-application moisture-changing rates, meaning that HW application compensated moisture for water-deficient skins (27.5–40% moisture), but not for wet skins (>41% moisture). Thus, the HW bath together with HW poultice exerted beneficial effects on skin appearances such as wrinkles, blotches and moisture/oiliness, some of which might ensue from enhanced antioxidant ability in blood, as was previously demonstrated for the HW bath.

Abstract
Skin disorders showing abnormal pigmentation are often difficult to manage because of their uncertain etiology or pathogenesis. Abnormal pigmentation is a common symptom accompanying aging skin. The association between skin aging and skin pigmentation abnormalities can be attributed to certain inherited disorders characterized by premature aging and abnormal pigmentation in the skin and some therapeutic modalities effective for both. Several molecular mechanisms, including oxidative stress, mitochondrial DNA mutations, DNA damage, telomere shortening, hormonal changes, and autophagy impairment, have been identified as involved in skin aging. Although each of these skin aging-related mechanisms are interconnected, this review examined the role of each mechanism in skin hyperpigmentation or hypopigmentation to propose the possible association between skin aging and pigmentation abnormalities.

Abstract
Melanin metabolism disorders may cause severe impacts on the psychological and social activities of patients. Different from the other two steps of melanin metabolism, namely synthesis and transport, little has been known about the mechanism of melanin degradation. Isoimperatorin (ISO) suppressed the activity of tyrosinase, an essential enzyme in melanin biosynthesis, hence, we investigated the effects and mechanism of ISO in melanin reduction. ISO stimulation significantly reduces the melanin contents and PMEL 17 protein levels; meanwhile, the activity and the protein levels of two critical lysosomal enzymes, Cathepsin B and Cathepsin D, can be significantly increased by ISO treatment. MiR-3619 inhibited the expression of CSTB and CSTD, therefore affecting ISO-induced degradation of melanin. In summary, ISO reduces the melanin content via miR-3619/CSTB and miR-3619/CSTD axes. ISO could be a potent skin-whitening agent, which needs further in vivo and clinical investigation.

Abstract
All eukaryotes have lysosomes which contain hydrolytic enzymes such as protease to degrade waste materials and cellular fragments. As a cellular organelle, lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself. Conversely, melanin has photochemical functions to protect tissue from the harmful effects of ultraviolet rays. However, too much of melanin leads to problems such as hyperpigmentation, requiring materials to maintain and control the amount of melanin. In this study, we found evidence of correlation between lysosome and melanin in a new eco-friendly material, MelanoDerm, a reconstituted 3D human skin model containing normal melanocytes and keratinocytes. Melanin content assay and cell viability were measured, using 2% kojic acid as positive control, while MelanoDerm was exposed to various concentrations of lysosome. Our results indicate that lysosome may be a useful cosmetic agent for the treatment of hyperpigmentation.

Thai herbal antipyretic 22 formula (APF22) inhibits UVA-mediated melanogenesis through activation of Nrf2-regulated antioxidant defense. Phytother Res 2018; 32:1546-1554.

Abstract
Thai herbal antipyretic 22 formula (APF22), a polyherbal formula, has been traditionally used to treat dermatologic problems including hyperpigmentation. Exposure of the skin to ultraviolet A (UVA) causes abnormal melanin production induced by photooxidative stress. This study thus aimed to investigate the protective effects of APF22 extracts and phenolic compounds, ferulic acid (FA), and gallic acid (GA; used as positive control and reference compounds), on melanogenesis through modulation of nuclear factor E2-related factor 2 (Nrf2) signaling and antioxidant defenses in mouse melanoma (B16F10) cells exposed to UVA. Our results revealed that the APF22 extracts, FA, and GA reduced melanin synthesis as well as activity and protein levels of tyrosinase in UVA-irradiated B16F10 cells. Moreover, APF22 extracts and both FA and GA were able to activate Nrf2-antioxidant response element signaling and promote antioxidant defenses including glutathione, catalase, glutathione peroxidase, and the glutathione-S-transferase at both mRNA and enzyme activity levels in irradiated cells. In conclusion, APF22 extracts suppressed UVA-mediated melanogenesis in B16F10 cells possibly via redox mechanisms involving activation of Nrf2 signaling and upregulation of antioxidant defenses. Moreover, pharmacological action of the APF22 extracts may be attributed to the phenolic compounds, FA, and GA, probably serving as the APF22's active compounds.
