The cosmetic sector is a multibillion-dollar industry that requires constant attention being paid to innovative product development and engagement. Notably, its market value is projected to exceed 750 billion U.S. dollars by 2025, and it is expanding as novel, climate-friendly, green, and sustainable components from natural sources are incorporated. This review is written based on the numerous reports on the potential applications of food-derived peptides while focusing on their possible uses in the formulation of cosmeceutical and skincare products. First, the production methods of bioactive peptides linked to cosmeceutical uses are described. Then, we discuss the obtainment and characterization of different anti-inflammatory, antimicrobial, antioxidant, anti-aging, and other pleiotropic peptides with their specific mechanisms, from various food sources. The review concludes with salient considerations of the cost of production and pilot scale operation, stability, compatibility, user safety, site-specificity, and delivery methods, when designing or developing biopeptide-based cosmeceutical products.

BACKGROUND: Heat shock protein 70 (HSP70) exhibits protective effects against ultraviolet (UV)-induced premature skin aging. A standardized extract of Asparagus officinalis stem (EAS) is produced as a novel and unique functional food that induces HSP70 cellular expression. To elucidate the anti-photoaging potencies of EAS, we examined its effects on HSP70 expression levels in UV-B-irradiated normal human dermal fibroblasts (NHDFs). METHODS: NHDFs were treated with 1 mg/mL of EAS or dextrin (vehicle control) prior to UV-B irradiation (20 mJ/cm). After culturing NHDFs for different time periods, HSP70 mRNA and protein levels were analyzed using real-time polymerase chain reaction and western blotting, respectively. RESULTS: UV-B-irradiated NHDFs showed reduced HSP70 mRNA levels after 1-6 h of culture, which were recovered after 24 h of culture. Treatment with EAS alone for 24 h increased HSP70 mRNA levels in the NHDFs, but the increase was not reflected in its protein levels. On the other hand, pretreatment with EAS abolished the UV-B irradiation-induced reduction in HSP70 expression at both mRNA and protein levels. These results suggest that EAS is capable to preserve HSP70 quantity in UV-B-irradiated NHDFs. CONCLUSIONS EAS exhibits anti-photoaging potencies by preventing the reduction in HSP70 expression in UV-irradiated dermal fibroblasts.

BACKGROUND/AIMS: Several factors contribute to the greater propensity for adverse drug reactions (ADRs) in the elderly, including the use of multiple drugs and pharmacokinetic and pharmacodynamic alterations due to aging. We evaluated the characteristics of ADRs in elderly versus younger adults. METHODS: ADRs were collected from a spontaneous reporting system at Seoul National University Hospital from February 2010 to September 2013. We analyzed causative drugs, clinical manifestations, and the severity of ADRs. RESULTS: In total, 15,541 ADRs were reported in patients 18 years of age or older. Common causative drug categories included nervous system, anti-neoplastics, and anti-infectives. The prevalence of ADRs due to respiratory drugs and cardiovascular drugs was higher in the elderly group (≥ 60 years) than in other groups. The most common clinical types were gastrointestinal and skin and appendage issues. The elderly group had a tendency to show a higher proportion of psychiatric, cardiovascular, hematological, and genitourinary symptoms. The proportions of severe ADRs were higher in the elderly groups and in male patients. CONCLUSIONS: Elderly patients were susceptible to ADRs related to respiratory and cardiovascular drugs. Psychiatric, cardiovascular, hematological, and genitourinary disorders account for a higher proportion of ADR symptoms in the elderly than in other age groups. Further efforts to understand, manage, and prevent ADRs in the elderly are required.

OBJECTIVETo explore the effect of microneedle combined with Lauromacrogol on skin capillary network.

METHODS24 male Leghone (1.5-2.0 kg in weight) were randomly divided into three groups as group A (microneedle combined with Lauromacrogol), B (microneedle combined with physiological saline) , and C(control). The cockscombs were treated. The specimens were taken on the 7th, 14th, 21th , and 28th day postoperatively. HE staining, immunohistochemical staining and special staining were performed for study of the number of capillary and collagen I/III , as well as elastic fibers.

RESULTSThe color of cockscombs in group A became lightening after treatment. The number of capillary decreased as showing by HE staining. The collagen I and III in group B was significantly different from that in group A and C (P < 0.05). Special staining showed proliferation of elastic fibers in group B.

CONCLUSIONSIt indicates that microneedle combined with Lauromacrogol could effectively reduce the capillary in cockscomb without any tissue fibrosis. Microneedle can stimulate the proliferation of elastic fiber, so as to improve the skin ageing process.

The Rejuran(R) is a new filler product made from purified polynucleotides. Here we present data from an animal study and a clinical trial to examine the durability, efficacy and safety of the Rejuran(R) on crow's feet. For the animal study, 25 mice were divided into three groups: Group 1 received phosphate buffered saline (PBS); Group 2 were treated with Yvoire(R); and Group 3 were treated with Rejuran(R). The durability and efficacy of each treatment were assessed by microscopy and staining. In the clinical trial, 72 patients were randomized to receive Rejuran(R) treatment for crow's feet on one side and Yvoire-Hydro(R) on the contralateral side, at a ratio of 1:1. Repeated treatments were performed every two weeks for a total of three times, over a total of 12 weeks' observation. All injections and observations of efficacy and safety were performed by the same two investigators. In the animal study, the Rejuran(R) group showed similar durability and inflammatory response to the Yvoire(R) group. Upon efficacy assessment, the Rejuran(R) group showed the greatest elasticity and collagen composition, and a significant difference in skin surface roughness and wrinkle depth. In the clinical trial, the primary and secondary objective efficacy outcome measure showed no statistical significance between the two groups, and in safety outcomes there were no unexpected adverse effects. Our data suggest that the Rejuran(R), as a new regenerative filler, can be useful to reduce wrinkles, by showing evidence for its efficacy and safety.

OBJECTIVETo study the effect of laminarin polysaccharide (LP) on the activity of matrix metalloproteinase of photoaging skins.

METHODKunming SPF mice were prepared with back hair shaved, and randomly divided into the control group, the model group, the LP low does group (LP-L, 1 mg x kg(-1)), the LP high dose group (LP-H, 5 mg x kg(-1)) and the Vit E (100 mg x kg(-1)) group. They were abdominally injected with drugs twice on a daily basis. Except for the control group, all groups were exposed to ultraviolet rays for 1 hour every day, five times on a weekly basis, with accumulated exposure dose of UVB being 21.60 J x cm(-2) and accumulated exposure dose of UVA being 84.02 J x cm(-2). Eight weeks later, exposed back skins were collected to detect thickness of dermis by HE stain, content of hydroxyproline (Hyp) by chemical colorimetry, and serum MMP-1 and TIMP-1 content by ELISA. In addition, matrix metalloproteinase-1 (MMP-1) mRNA and relative content of tissue inhibitor of metalloproteinase-1 (TIMP1) mRNA was analyzed with Real-time PCR.

RESULTCompared with the model group, the LP-H group could significantly increase the thickness of dermis, skin Hyp content and serum TIMP-1 level, and decrease relative content of MMP-1 mRNA in skin and MMP-1 content in serum.

CONCLUSIONLP can regulate the metabolism of collagen photoaging skins by adjusting the activity of matrix metalloproteinase.

It has been proposed that the pro-inflammatory catalytic activity of cyclooxygenase-2 (COX-2) plays a key role in the aging process. However, it remains unclear whether the COX-2 activity is a causal factor for aging and whether COX-2 inhibitors could prevent aging. We here examined the effect of COX-2 inhibitors on aging in the intrinsic skin aging model of hairless mice. We observed that among two selective COX-2 inhibitors and one non-selective COX inhibitor studied, only NS-398 inhibited skin aging, while celecoxib and aspirin accelerated skin aging. In addition, NS-398 reduced the expression of p53 and p16, whereas celecoxib and aspirin enhanced their expression. We also found that the aging-modulating effect of the inhibitors is closely associated with the expression of type I procollagen and caveolin-1. These results suggest that pro-inflammatory catalytic activity of COX-2 is not a causal factor for aging at least in skin and that COX-2 inhibitors might modulate skin aging by regulating the expression of type I procollagen and caveolin-1.

Cordycepin (3'-deoxyadenosine) has been shown to exhibit many pharmacological activities, including anti-cancer, anti-inflammatory, and anti-infection activities. However, the anti-skin photoaging effects of cordycepin have not yet been reported. In the present study, we investigated the inhibitory effects of cordycepin on matrix metalloproteinase-1 (MMP-1) and -3 expressions of the human dermal fibroblast cells. Western blot analysis and real-time PCR revealed cordycepin inhibited UVB-induced MMP-1 and -3 expressions in a dose-dependent manner. UVB strongly activated NF-kappa B activity, which was determined by I kappa B alpha degradation, nuclear localization of p50 and p65 subunit, and NF-kappa B binding activity. However, UVB-induced NF-kappa B activation and MMP expression were completely blocked by cordycepin pretreatment. These findings suggest that cordycepin could prevent UVB-induced MMPs expressions through inhibition of NF-kappa B activation. In conclusion, cordycepin might be used as a potential agent for the prevention and treatment of skin photoaging.
