Eco-Friendly Sustainable Nanocarriers to Treat Oxidative Stresses and Skin Aging-Related Ailments, Valorization of a By-Product

The peel from Citrus-sinensis L. is a medicinally significant food waste, and its extract (O-Ext) could be significant against oxidative stresses and skin aging, However, the penetration barriers, instability in formulation, undefined toxicities, and enzymatic activities make the O-Ext difficult to formulate and commercialize. The goal of this study was to evaluate O-Ext against oxidative stress, prepare O-Ext-loaded nano-lipid carriers (O-NLCs), and load them into topical O/W-emulsion (O-NLC-E) to improve O-Ext permeation and its in vivo antiaging effects. TPC, TFC, DPPH activity, and mineral/metal contents of O-Ext were determined via atomic-absorption spectroscopy. For bioactive compounds profiling, GC-MS analysis was carried out. O-NLCs were prepared and tested for physicochemical attributes, while HaCaT and fibroblast cells were used to study permeation and cytotoxicity. The kinetic characteristics of ex vivo permeation through rat skin were established, following the Higuchi model. Following written consent, safety investigations were conducted on human volunteers for three months, where optimized O-NLC-E and B-NLC-E were regularly applied on cheeks. Non-invasive procedures were used to assess the volunteer's skin erythema, TEWL, sebum level, melanin, hydration, pH, elasticity, and pore sizes after specified intervals. The results demonstrated that applying O-NLC-E formulation to the skin of volunteers directed significant antiaging benefits. The study offers nanotechnology-based sustainability approach against skin ageing.

Potential Anti-aging Components From Moringa oleifera Leaves Explored by Affinity Ultrafiltration With Multiple Drug Targets

Moringa oleifera (M. oleifera), widely used in tropical and subtropical regions, has been reported to possess good anti-aging benefits on skincare. However, the potential bioactive components responsible for its anti-aging effects, including anti-collagenase, anti-elastase, and anti-hyaluronidase activities, have not been clarified so far. In this study, M. oleifera leaf extracts were first conducted for anti-elastase and anti-collagenase activities in vitro by spectrophotometric and fluorometric assays, and the results revealed that they possessed good activities against skin aging-related enzymes. Then, multi-target bio-affinity ultrafiltration coupled to high-performance liquid chromatography-mass spectrometry (AUF-HPLC-MS) was applied to quickly screen anti-elastase, anti-collagenase, and anti-hyaluronidase ligands in M. oleifera leaf extracts. Meanwhile, 10, 8, and 14 phytochemicals were screened out as the potential anti-elastase, anti-collagenase, and anti-hyaluronidase ligands, respectively. Further confirmation of these potential bioactive components with anti-aging target enzymes was also implemented by molecule docking analysis. In conclusion, these results suggest that the M. oleifera leaves might be a very promising natural source of anti-aging agent for skincare, which can be further explored in the cosmetics and cosmeceutical industries combating aging and skin wrinkling.

Effect of scratching and friction on human skin in vivo

OBJECTIVE

To investigate effect of scratching and friction on human skin function and functional differences between scratching and friction.

METHOD

Forty healthy volunteers were enrolled. Scratching and friction behavior was modeled by scalpel and sandpaper simulation to forearm for 80 times, respectively. Noninvasive bioengineering devices were used to measure basic skin physiological parameters and exfoliated stratum corneum collected and protein quantified. Parameters were recorded at baseline (BL) and after every 20 times interventions (20, 40, 60, and 80 times).

RESULTS

Compared to BL, transepidermal water loss (TEWL) value increased significantly at both scratched and friction sites (P < .001) with a significant higher value for friction (P < .001). There was no significant difference in stratum corneum hydration (SCH) value postscratching (P > .05), while it decreased first and then increased significantly at friction site (P < .001). Roughness values (contract (CONT), variety (VAR), and scaliness (SEsc)) were raised significantly at both sites (P < .001). Net change in CONT and SEsc values of friction was higher than scratched sites (P > .05). There was no significant difference in blood flow after both scratching and friction (P > .05). Quantity of keratinocyte protein from friction sites was statistically higher than scratching after 80 times interventions (P < .05).

CONCLUSION

Both noninvasive detections and protein quantification indicated more damage from friction, which may have significance for behavior guidance of patients with pruritus and implication for further investigation.

Noninvasive evaluation of the influence of aucubin-containing cosmetic macroemulsion on selected skin parameters

BACKGROUND

Objective evaluation of skin condition on the basis of noninvasive methods has become obligatory and may be a good strategy for verifying the efficiency of new cosmetic active ingredients.

AIM

The aim of this study was to assess the influence of aucubin-containing cosmetic macroemulsion on skin parameters using the skin testing equipment.

PATIENTS/METHODS

The study was carried out on the group of 25 female volunteers of the mean age 27 ± 2 years. The skin parameters were measured using the following devices: Tewameter^® TM 300 (transepidermal water loss, TEWL), Corneometer^® CM 825 (skin hydration), Cutometer^® MPA 580 (skin elasticity), Visioscan^® VC 98 (skin topography), and Visioline^® VL 650 (skin macrorelief). All measurements were performed on the inner part of the left forearm.

RESULTS

The skin parameters measured revealed the beneficial influence of aucubin on TEWL and skin hydration level. The application of aucubin-enriched cream caused more significant improvements of all determined SELS parameters, in comparison with cream without it. An analogous tendency was noticed in the case of skin macrorelief parameters; the addiction of the active ingredient led to a decrease in the value of total wrinkle area and diminished the mean length and depth of single wrinkles.

CONCLUSIONS

Noninvasive methods of skin testing have provided a possibility of objective evaluation of the action of new active ingredients in cosmetic formulations. The study has proved the positive influence of aucubin on effectiveness of cosmetic macroemulsions, diminishing TEWL, increasing skin hydration level, and improving the values of SELS and skin macrorelief parameters.

A review of properties, nutritional and pharmaceutical applications of Moringa oleifera: integrative approach on conventional and traditional Asian medicine

Moringa oleifera L. from the Moringaceae family is a perennial tree widely cultivated in many tropic regions and easily grown even in adverse conditions. M. oleifera is also known as the miracle tree, which for centuries has been indicated for traditional medicine. With no reports of side effects, in doses achievable by ingestion, different parts of M. oleifera is used to treat several conditions, such as malnutrition, diabetes, blindness, anemia, hypertension, stress, depression, skin, arthritis, joints and kidney stones disorders. This plant also showed capacity of helping in maintenance of the cardiovascular system health, blood-glucose levels and providing anti-oxidant, anti-inflammatory and anti-cancer activity as well as the regulation of urinary tract and lactation in nursing women. The seed and leaves powder has water purification properties through flocculation. It also supplements the food in the human diet and in the fortification of livestock feed, especially in developing countries. So, M. oleifera properties have also been applied to cosmetic and byproducts industries due to the high nutritive and protective properties of its seed oil. According to the holistic or traditional medicine, M. oleifera has very relevant therapeutic properties and applications depending on the constitution, somatic and psychological needs of patients. It is usually referred as a natural product that can treat different physical and psychological health aspects, offering an energetic action and structural rebuilder of the body and promoting emotions of highly positive attitudes towards life. The high and specific immunological potential of M. oleifera leads us to suggest an in-depth study to assess the hypothesis of conferring a supportive effect against Covid-19 disease.

Assessment of non-invasive techniques and herbal-based products on dermatological physiology and intercellular lipid properties

Skin is the largest external organ of the human body. It acts as a barrier to protect the human body from environmental pollution, mechanical stress, and excessive water loss. The defensive function resides primarily on top of the epidermis layer commonly known as stratum corneum (SC). Human SC consists of three major lipids, namely ceramide, free fatty acid, and cholesterol that comprise approximately 50%, 25%, and 25% of the total lipid mass, respectively. The optimal composition of SC lipids is the vital epidermal barrier function of the skin. On the other hand, skin barrier serves to limit passive water loss from the body, reduces chemical absorption from the environment, and prevents microbial infection. In contrast, epidermal lipids are important to maintain the cell structure, growth and differentiation, cohesion and desquamation as well as formation of a permeability barrier. Multiple non-invasive in vivo approaches were implemented on a regular basis to monitor skin physiological and intercellular lipid properties. The measurement of different parameters such as transepidermal water loss (TEWL), hydration level, skin elasticity, collagen intensity, melanin content, sebum, pH, and tape stripping is essential to evaluate the epidermal barrier function. Novel non-invasive techniques such as tape stripping, ultrasound imaging, and laser confocal microscopy offer higher possibility of accurate and detailed characterisation of skin barrier. To date, these techniques have also been widely used to determine the effects of herbal plants in dermatology. Herbal plants have been traditionally used for ages to treat a variety of skin diseases, as reported by the World Health Organisation (WHO). Their availability, lower cost, and minimal or no side effects have created awareness among society, thus increase the demand for natural sources as the remedy to treat various skin diseases. This paper reviews several non-invasive techniques and evaluations of herbal-based product in dermatology.

First Report on Evaluation of Basic Nutritional and Antioxidant Properties of Moringa Oleifera Lam. from Caribbean Island of Saint Lucia

Moringa oleifera Lam. has been considered as a multipurpose tree. The studies on it focus on its variable nutritional benefits. It is growing in many regions, but information about nutritional properties of those growing in the Caribbean is missing. The present study focused on biochemical analysis of main nutritional and antioxidant properties in plant material-dried leaves and seeds-of Moringa oleifera. The composition of lipids, proteins, and vitamin E was evaluated in powdered dried leaves and seeds. Fatty acids were evaluated in oil extracted from the moringa seeds. Potential antioxidant properties of the moringa were evaluated in extract from crushed and powdered leaves, as well as from the powdered seeds. The total amounts of lipids, proteins, and vitamin E were higher in powdered seeds (31.85%, 35.13%, and 220.61 mg/kg) than in powdered leaves (12.48%, 20.54%, and 178.10 mg/kg). The main compound of fatty acids presented oleic acid (76.78%) in seeds' oil and oleic (25.01%), palmitic (24.84%), and linolenic (24.71%) acids in leaves. Neohesperidin (126.8 mg/kg), followed by chlorogenic acid (99.96 mg/kg) and quercetin (43.44 and 21.44 mg/kg) were main phenolic compounds identified. Total phenols in powdered leaves' extract (635.6 mg GAE/L) was higher than in powdered seeds' extract (229.5 mg GAE/L). The activity against superoxide radical and hydroxyl radical was 92.4% and 73.1% by leaves' powder extract and 83.6% and 60.7% by crushed-leaf extract; seed-powder extract exhibited a pro-oxidation activity (-68.4%) against superoxide radical and the lowest antioxidant effect against the hydroxyl radical (55.0%).

Anti-pollution cosmetic-based one-step formation of w/o/w multiple emulsion containing D-biotin for skin protection: fabrication and in vitro and in vivo evaluation

Continuous contact of air pollutants on human skin has produced early ageing and led to roughness, dryness, poor elasticity, increased wrinkling and irregular pigmentation of the skin. The present study was carried out to fabricate an anti-pollution cosmetic-based w/o/w multiple emulsion containing D-biotin, prepared by a one-step formation as protection for the skin against the effects of air pollutants and further used for in vitro and in vivo evaluation. A similar multiple emulsion without D-biotin was also prepared in the same way. Each of the tested multiple emulsions (CB2 and CF2) was applied to the cheeks of 15 human volunteers for a testing period of 90 days. Both emulsions were assessed for skin melanin, erythema, hydration and elasticity values. The droplet sizes of CB2 and CF2 stored in the dark were 10.92 ± 0.23 and 15.4 ± 0.12 μm, respectively. The size distributions of CB2 and CF2 ranged from 4.55 ± 0.1 to 26.056 ± 0.34 μm and from 1.97.16 ± 1.2 to 45.13 ± 2.17 μm, respectively. The rheological parameters showed non-Newtonian, pseudo-plastic and shear thinning behaviour, while pH remained within an acceptable range. No considerable physical changes were observed. The skin irritation testing indicated that CB2 and CF2 were safe after application and did not cause any skin irritation. The skin melanin, erythema, moisture and elasticity values of both the right and left cheeks of the volunteers were measured at baseline visits: 15, 30, 45, 60, 75 and 90 days of time intervals. While CB2 showed insignificant effects, therefore, it was demonstrated that CF2 decreased skin erythema content and increased skin elasticity and hydration significantly but had an insignificant effect on skin melanin content with respect to time. Good sensory attributes were also achieved. Therefore, CF2 is a promising new approach for protection of the skin from the deleterious effects of air pollutants.

Forearm skin aging: characterization by instrumental measurements

BACKGROUND

The intrinsic ageing and photoaged skin present biomechanical and morphological differences, which are reflected in the appearance of roughness, superficial and deep wrinkles, atrophy, reduced elasticity, hypo- and hyperpigmentation and actinic keratosis.

OBJECTIVE

To evaluate and compare the characteristics of the flexor (with a predominance of intrinsic ageing) and extensor (chronically exposed to sunlight and other environmental factors, with a predominance of photoageing) skin surfaces of the forearms.

METHODS

Interventional, prospective, diagnostic study, including 23 females, aged over 60 years. The extensor and flexor faces of forearms were compared in relation to clinical parameters and non-invasive instrumental measurements, such as skin surface, elasticity, hydration as well as dermal thickness and echogenicity.

RESULTS

Regarding the water content of the stratum corneum, the flexor face presented an average value higher than the extensor face. The average of measures obtained through images of high-frequency ultrasound demonstrated greater echogenicity of flexor face compared to the extensor face. The measurements of the skin surface showed significant differences between the faces. The roughness and scaliness were lower in the flexor face. Regarding the depth of wrinkles, there was no significant difference between the faces. The average of the measurements was slightly higher in the flexor face, which demonstrated that wrinkles are present in the intrinsic ageing and photoageing. The presence of elastosis and the reduction in elasticity in the clinical aspect of the photoaged face of forearms were according to the results of the non-invasive measurements.

CONCLUSION

Meaningful differences in the biophysical characteristics of the extensor and flexor faces of the forearms were detected. Because the non-invasive instrumental measurements correlated with clinical findings, they may represent useful tools to assess efficacy and safety of skin ageing treatments in clinical research.

Proretinal nanoparticles: stability, release, efficacy, and irritation

Despite many potent biological activities, retinoids such as retinoic acid (RA) and retinal possess dose-related broad side effects. In this study, we show that this problem, which has been unsolvable for a long time, can be tackled through a controlled release strategy in which retinal is continuously delivered to the skin via sustained release from proretinal nanoparticles. The water dispersible proretinal nanoparticles are stable when kept in water at neutral pH and at room temperature for 8 months under light-proof conditions, and show sustained release of retinal into human synthetic sebum at a pH of 5. In the daily topical application tests performed for 4 weeks on rats' skin, the nanoparticles showed superior ability to increase epidermal thickness compared to RA and retinal, with no skin irritation observed for the proretinal particles, but severe skin irritation observed for RA and free retinal. When tested under occlusion conditions in human volunteers, insignificant skin irritation was observed for the proretinal nanoparticles. The 12-week, double-blind, split-face study on human volunteers indicates better antiaging efficacy of the particles as compared to the free RA.

Anti-Aging Potential of Phytoextract Loaded-Pharmaceutical Creams for Human Skin Cell Longetivity

The exposure to ultraviolet radiations (UVR) is the key source of skin sunburn; it may produce harmful entities, reactive oxygen species (ROS), leading to aging. The skin can be treated and protected from the injurious effects of ROS by using various pharmaceutical formulations, such as cream. Cream can be loaded with antioxidants to quench ROS leading to photo-protective effects. Moreover, modern medicines depend on ethnobotanicals for protection or treatment of human diseases. This review article summarizes various in vivo antioxidant studies on herbal creams loaded with phyto-extracts. These formulations may serve as cosmeceuticals to protect skin against injurious effects of UVR. The botanicals studied for dermatologic use in cream form include Acacia nilotica, Benincasa hispida, Calendula officinalis, Camellia sinensis, Camellia sinensis, Nelumbo nucifera, Capparis decidua, Castanea sativa, Coffea arabica, Crocus sativus, Emblica officinalis Gaertn, Foeniculum vulgare, Hippophae rhamnoides, Lithospermum erythrorhizon, Malus domestica, Matricaria chamomilla L., Moringa oleifera, Morus alba, Ocimum basilicum, Oryza sativa, Polygonum minus, Punica granatum, Silybum marianum, Tagetes erecta Linn., Terminalia chebula, Trigonella foenum-graecum, and Vitis vinifera. The observed anti-aging effects of cream formulations could be an outcome of a coordinating action of multiple constituents. Of numerous botanicals, the phenolic acids and flavonoids appear effective against UVR-induced damage; however the evidence-based studies for their anti-aging effects are still needed.
