Oral Intake of Enzymatically Decomposed AP Collagen Peptides Improves Skin Moisture and Ceramide and Natural Moisturizing Factor Contents in the Stratum Corneum

The stratum corneum (SC) is the outermost layer of the epidermis and plays an important role in maintaining skin moisture and protecting the skin from the external environment. Ceramide and natural moisturizing factor (NMF) are the major SC components that maintain skin moisture. In this study, we investigated whether the oral intake of enzymatically decomposed AP collagen peptides (APCPs) can improve skin moisture and barrier function by assessing changes in the ceramide and NMF contents in the SC after APCP ingestion with the aim to develop a skin functional food. Fifty participants orally ingested APCP (1000 mg) or placebo for 12 weeks, and then, skin hydration and skin texture were evaluated. SC samples were collected to analyze skin scaling, ceramide, and NMF contents. Participants in the APCP group exhibited improved skin moisture content by 7.33% (p = 0.031) and roughness by −4.09% (p = 0.036) when compared with those in the placebo group. NMF content; the amounts of amino acids (AA), including glycine and proline; and AA derivatives were significantly increased in the APCP group (31.98 μg/mg protein) compared to those in the placebo group (−16.01 μg/mg protein) (p = 0.006). The amounts of total ceramides and ceramide subclasses were significantly higher in the APCP group than in the placebo group (p = 0.014). In conclusion, our results demonstrate that APCP intake improves skin moisture and increase the ceramide and NMF contents in the SC, thereby enhancing the skin barrier function.

Photodynamic reparative skin regeneration using application of photosensitizer gel based on chlorin e6

The results of a study of the clinical effectiveness of the correction of involutional changes in the skin by the method of photodynamic therapy (PDT) with the use of a photosensitizer gel (PS), the active substance of which is the trismeglumine salt of chlorin e6, are presented. The data of fluorescence spectroscopy for monitoring the level of PS fluorescence in order to determine the optimal time of its exposure are demonstrated. The study of the optimal exposure time involved 80 patients with different skin phototypes. The study of the effectiveness of PDT involved 42 patients aged 44–68 years with signs of chrono- and photoaging. The PDT procedure was performed by irradiating the entire surface treated with the PS with a power density of 100 mW/cm2, a light dose of 120–140 J/cm2, a laser radiation wavelength of 660 nm, and a light beam area of 400–800 cm2. It was found that exposure to PS for 10–20 min gives the highest fluorescence and does not depend on the skin phototype. The clinical effect of PDT was achieved in 85.7% of patients; there were no negative subjective sensations. Moisture metrics increased on the skin of the face by 53%, reaching the control values in young healthy volunteers, on the skin of the hands - by 64%. Elastometry indicators on the skin of the face and hands increased by 19% and 16%, respectively. Thus, the PDT procedure with PS based on chlorin e6 is an effective method for correcting involutional changes in the skin, leads to a pronounced clinical effect, improves the parameters of skin moisture measurement and elastometry, and passes without undesirable local reactions. Optical coherence tomography showed an increase in collagen ordering.

The influence of hypothermia prevention by application of skin moisture absorbent on the value of body temperature, body weight and blood parameters in piglets

ABSTRACT Reducing the mortality rate is of a great economic importance for pig farming. Therefore, it is necessary to define the conditions in the farrowing unit based on the performance of the piglets, and specific hematological and biochemical parameters. Therefore, the aim of this paper is to examine the importance of using skin moisture absorbent and its influence in preventing hypothermia, which causes great economic losses in pig production. The experiment was set up on a commercial farm in Serbia and included 92 pigs divided into the experimental and control group. Body temperature values, body weight and blood parameters were monitored. The obtained values indicate that there is a significantly positive correlation of body temperature change and body weight values, and body temperature showed a significantly higher increase in the experimental group compared to the control group. The results obtained from hematological and biochemical parameters provide a clearer picture of the metabolic processes in piglets in the farrowing unit and can be used to further improve pig production and as a complement to genetic enhancement.

Study of Platelet Rich Plasma Injection versus Plasma Gel in Periorbital Rejuvenation

Background Aging of the skin consists of a combination of genetically predisposed factors (intrinsic aging) and environmental factors (photo aging). The resulting clinical manifestations include mottled pigmentation, wrinkles, and change of the superficial texture leading to coarseness of the skin Dermal components such as collagen and elastic fibers gradually decrease, skin loses its elasticity and shows wrinkles. Loss of skin moisture and subcutaneous fat accelerates the process. Objective To evaluate the efficacy, possible side effects, durability and study of platelet rich plasma injection versus Plasma gel injection in periorbital rejuvenation. Methods This comparative split face study included 40 females with periorbital wrinkles and/or dark circles recruited from the Dermatology outpatient clinic of Ain-Shams University Hospitals.Right periorbital wrinkles was injected by platelet rich plasma while left periorbital side was injected by plasma gel. Results Treatment with plasma gel resulted in significant improvement of periorbital wrinkles with minimal complications compared to platelet rich plasma. While, dark haloes and skin texture were minimally affected whether with plasma gel or PRP injection. Conclusion Plasma gel as well as platelet rich plasma injections may play role in treatment of periorbital wrinkles but mostly for short durations. Plasma gel injection is more effective in periorbital rejuvenation than PRP injection although it has relatively higher complications rate. Both plasma gel and PRP injections has only minimal role in treatment of periorbital dark hallows.

Anti-Aging Activities of Asparagus Gel Ethanol Extract in Cosmetic Gel Agent for Facial Skin

Asparagus is a vegetable that contains phenolic compounds with antioxidant properties that scavenges aging-triggering free radicals. This study aimed to investigate the components and anti-aging potentials of Ethanol Extract form Asparagus (EEA). The study was performed in February 2020 at the Pharmacy Laboratory, University of North Sumatera. The EEA was obtained through maceration using 96% ethanol. An antioxidant assay was performed and the total phenol and flavodoid content were determined using the spectroscopic method. Three gel formulas with different concentrations of EEA was prepared (F1: 1.5%, F2: 2.5%, and F3: 3.5%), and F0 was used as control. The parameters evaluated were moisture, oil content, texture, collagen, wrinkle, pigment, sensitivity, and pore. The result showed that asparagus had a moderate antioxidant activity (IC50: 118,992) with the total phenol and flavonoid contents of 15,9407 mg GAE/g and 3,2286 mg QE/g extract, respectively. The highest aging activities was seen in F3 (3.5%), followed by F2 (2.5%) and F1 (1.5%). The percentage of moisture, oil, texture, collagen, wrinkle, spot, sensitivity, and pore recovery were found to be 40.15%, 49.73%, 71.76%, 17.70%, 70.93%, 49.34%, 42.56% and 25.31%, respectively. Hence, it can be concluded that the EEA Gel at the highest concentration (3.5%) has a high content of phenol and flavonoid which can improve the skin moisture, oil content, texture, collagen, wrinkles, spots, sensitivity, and pores, which promotes anti-aging activities.

Hydrolyzed Collagen Combined with Djulis and Green Caviar Improve Skin Condition: A Randomized, Placebo-Controlled Trial

Aging is a natural process that will cause physiological changes in organs. The effects of djulis and green caviar in skincare are currently unclear. This study combined hydrolyzed collagen with djulis and green caviar to develop new functional formulas that improve skin parameters. Fifty subjects were randomly assigned and divided into a placebo group (n=25) and a collagen drink group (n=25), and gave 50 ml of collagen of a collagen drink or placebo drink daily for 28 days, and we examined skin moisture, elasticity, gloss, spot, wrinkle, roughness, smoothness, pore, collagen and erythema. We find that intake of collagen drinks group improved skin parameters at 14 days and 28 days compared with baseline (0 day). The collagen drinks group improved skin parameters at 28 days compared with the placebo group. This clinical study proved the combination of collagen with djulis and green caviar for the substantial improvements in moisture, elasticity, gloss, spot, wrinkle, roughness, smoothness, pore, collagen, and erythema in the skin.

Taxonomic profiling of skin microbiome and correlation with clinical skin parameters in healthy Koreans

The interest in skin microbiome differences by ethnicity, age, and gender is increasing. Compared to other ethnic groups, studies on the skin microbiome of Koreans remains insufficient; we investigated facial skin microbiome characteristics according to gender and age among Koreans. Fifty-one healthy participants were recruited, the facial skin characteristics of each donor were investigated, their skin bacterial DNA was isolated and metagenomic analysis was performed. The donors were divided into two groups for age and sex each to analyze their skin microbiomes. Moreover, we investigated the correlation between the skin microbiome and clinical characteristics. The alpha diversity of the skin microbiome was significantly higher in the elderly, and beta diversity was significantly different according to age. The comparative skin microbials showed that the genus Lawsonella was more abundant in the younger age group, and Enhydrobacter was predominant in the older age group. Staphylococcus and Corynebacterium were more abundant in males, while Lactobacillus was more abundant in females. Lawsonella had a negative correlation with skin moisture and brown spots. Staphylococcus and Corynebacterium both had negative correlations with the number of UV spots and positive correlations with transepidermal water loss (TEWL). Furthermore, Staphylococcus aureus had a negative correlation with skin moisture parameters.
