RESUMEN
Olive leaf is a rich source of phenolic compounds with numerous activities related to skin health and appearance. In this study, a green extraction method was developed using eco-friendly solvents: polypropylene glycol (PPG), lactic acid (LA), and water. The optimal extraction conditions were established, including solvent, extraction time, technique (magnetic stirrer vs. ultrasound-assisted extraction), and herbal material/solvent ratio. The composition of the solvent mixture was optimized using a mixture design. The content of phenolic compounds, including oleuropein and verbascoside, was determined using high-performance liquid chromatography (HPLC) and spectrophotometric methods. Using different extraction conditions, three extracts were prepared and their phytochemical compositions and antioxidant and skin-related bioactivities were investigated. The extracts were excellent inhibitors of elastase, collagenase, tyrosinase, and lipoxygenase. The best activity was shown by the extract richest in phenolics and prepared using magnetic-stirrer-assisted extraction for 20 min, with 0.8 g of herbal material extracted in 10 mL of PPG/LA/water mixture (28.6/63.6/7.8, w/w/w), closely followed by the extract prepared using the same extraction conditions but with 0.42 g of herbal material. The investigated PPG/LA/water mixtures contributed to the overall enzyme-inhibitory activity of the extracts. The prepared extracts were appropriate for direct use in cosmetic products, thus saving the time and energy consumption necessary for the evaporation of conventional solvents.

The skin health benefits of seaweeds have been known since time immemorial. They are known as potential renewable sources of bioactive metabolites that have unique structural and functional features compared to their terrestrial counterparts. In addition, to the consciousness of green, eco-friendly, and natural skincare and cosmetics products, their extracts and bioactive compounds such as fucoidan, laminarin, carrageenan, fucoxanthin, and mycosporine like amino acids (MAAs) have proven useful in the skincare and cosmetic industries. These bioactive compounds have shown potential anti-photoaging properties. Furthermore, some of these bioactive compounds have been clinically tested and currently available in the market. In this contribution, the recent studies on anti-photoaging properties of extracts and bioactive compounds derived from seaweeds were described and discussed.

Cosmetics are widely used by people around the world to protect the skin from external stimuli. Consumer preference towards natural cosmetic products has increased as the synthetic cosmetic products caused adverse side effects and resulted in low absorption rate due to the chemicals' larger molecular size. The cosmetic industry uses the term "cosmeceutical", referring to a cosmetic product that is claimed to have medicinal or drug-like benefits. Marine algae have gained tremendous attention in cosmeceuticals. They are one of the richest marine resources considered safe and possessed negligible cytotoxicity effects on humans. Marine algae are rich in bioactive substances that have shown to exhibit strong benefits to the skin, particularly in overcoming rashes, pigmentation, aging, and cancer. The current review provides a detailed survey of the literature on cosmeceutical potentials and applications of algae as skin whitening, anti-aging, anticancer, antioxidant, anti-inflammation, and antimicrobial agents. The biological functions of algae and the underlying mechanisms of all these activities are included in this review. In addition, the challenges of using algae in cosmeceutical applications, such as the effectiveness of different extraction methods and processing, quality assurance, and regulations concerning extracts of algae in this sector were also discussed.

BACKGROUND: Cosmetics are the products used to beautify the skin. Emulsion is a fine dispersion of two or more immiscible liquids. Sphaeranthus indicus is claimed to be used for skin beautification in folk medicine. Multiple emulsion was formulated containing the extract of S indicus flowers. AIMS: This research study indicates that extract of S indicus flowers contains sufficient amount of polyphenols and also possess good antioxidant activity with mushroom tyrosinase inhibition activity. METHOD: Further, stable multiple emulsion was developed and stability testing was performed for 180 days by keeping the multiple emulsion at 8°C ± 1, 25°C ± 1, 40°C ± 1, and 40°C ± 1 with 75% ± 1 RH. Parameters checked were color change, phase distribution, viscosity, droplet size and size distribution, pH determination, and electrical conductivity. Sun protection factor (SPF) was determined which also showed promising results. Skin testing on human volunteers was done for 3 months after biosafety profiling of the most stable multiple emulsion. RESULTS: This also showed remarkable effects. Skin erythema, melanin, and sebum were reduced. Skin hydration and elasticity were increased. There was also reduction in the number of skin large and small skin pores. Skin spot area was also reduced by the use of multiple emulsion loaded with S indicus flower extract. ANOVA test showed that all the effects produced on skin were significant, ie, P ≤ .05. CONCLUSION: A stable multiple emulsion was developed which produced significant cosmetic effects on human skin.

BACKGROUND: Fitzroya cupressoides, commonly known as alerce, is an endemic conifer unique to southern South America. Alerce wood is renowned for its durability and resistance to biological degradation due to the presence of a particular class of secondary metabolite. Alerce extracts have been used in traditional medicine for different skin lesion treatments. AIMS: To develop a cell culture system to produce alerce extract and evaluate its cytotoxicity and effects on in vitro wound healing. METHODS: Cell cultures and aqueous extracts were prepared from alerce needles. Cytotoxicity was evaluated in keratinocytes (HaCaT line) and melanocites (C32 line) using the XTT assay. Wound healing was assayed with the scratch test in HaCaT cells, using mitomycin C to evaluate the role of cell division in the wound closure. RESULTS: Alerce cell culture extract has a significant effect on wound healing at different concentrations. No positive effects on the viability of normal and cancerous skin cells were observed. These results suggest that alerce extracts stimulate cell division in human skin epidermal cells in the context of wound repair. CONCLUSIONS: Bioactive compounds extracted from alerce cell cultures show promise as ingredients in dermocosmetic formulations, but further clinical studies are required to support these findings at the tissue level.

Large amounts of agro-industrial waste are being generated each year, leading to pollution and economic loss. At the same time, these side streams are rich source of active compounds including antioxidants. Recovered compounds can be re-utilized as food additives, functional foods, nutra-/pharmaceuticals, cosmeceuticals, beauty products, and bio-packaging. Advanced extraction techniques are promising tools to recover target compounds such as antioxidants from agro-industrial side streams. Due to the disadvantages of classical extraction techniques (such as large amounts of solvents, increased time of extraction, large amounts of remaining waste after the extraction procedure, etc.), and advanced techniques emerged, in order to obtain more efficient and sustainable processes. In this review paper aspects regarding different modern extraction techniques related to recovery of antioxidant compounds from wastes generated in different industries and their applications are briefly discussed.

Berberis vulgaris is rich in berberine, an isoquinoline alkaloid, with antidiabetic activity, often used topically for skin-related problems. The aim of this work was to develop a "green" method for berberine extraction using mixtures of water with glycerol, a non-toxic, environmentally-friendly solvent. Response surface methodology based on Box-Behnken design was used to optimize the experimental conditions for ultrasound-assisted extraction of berberine and anti-radical components from B. vulgaris root bark. The independent variables were temperature (X1), glycerol concentration (X2), and ultrasound power (X3), while the responses were berberine concentration and DPPH radical scavenging activity of the extracts (RSA IC50). The response values of the extracts prepared at optimum conditions were (response, X1, X2, X3): berberine yield (145.5 µg/mL; 80 °C, 50%, 144 W) and RSA IC50 (58.88 µL/mL; 80 °C, 30%, 720 W). The observed values deviated from the predicted values by -3.45% and 6.42% for berberine and RSA IC50, respectively, thus indicating the validity of the selected models. The prepared extracts demonstrated antioxidant, anti-melanogenic, and anti-inflammatory activity, as well excellent α-glucosidase and α-amylase inhibitory activity. The displayed biological properties and lack of glycerol toxicity makes the prepared extracts suitable for direct inclusion into antidiabetic and dermatologic food supplements and topical products.

The anti-melanogenic principle of peony (Paeonia officinalis subsp. officinalis) seeds was elucidated via activity-guided isolation. Resveratroloside (trans-resveratrol-4'-O-beta-d-glucopyranoside) was found to be the main metabolite of P. officinalis subsp. officinalis seeds and its tyrosinase inhibiting activity was confirmed via an enzymatic assay. Furthermore, the in vitro activity and the therapeutic window were studied employing the murine melanoma cell line B16F10. The results from the conducted stability assay and the high content of resveratroloside in the seeds (i.e. 10.4% dw) motivated us to push the extract forward to an in vivo tolerance assay. A clinical study with forty Caucasian participants proofed a good skin-tolerance with high moisture effect and reduction of pores.

The present investigation was aimed to find out the sun protection factor (SPF) and antioxidant potential of geranium essential oil (GEO) and calendula essential oil (CEO) because having a combination of these two properties moves up the oils as an active ingredient of various cosmeceutical formulations for their preventive and protective properties. Essential oils were obtained by hydrodistillation of Pelargonium graveolens leaves (GEO) and Calendula officinalis flowers (CEO). The composition and identification of chemical constituents of oils were determined by GCMS analysis. Free radical scavenging activity was measured by nitric oxide scavenging activity and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. It was observed that both GEO and CEO have the potential to reduce or prevent oxidative stress and can be used in skin care regimen to slow down skin aging via its antioxidant properties. In vitro SPF was determined by a very simple and rapid spectroscopic method. SPF value of GEO and CEO was found to 6.45 and 8.36, respectively. The SPF of CEO was higher than GEO, and the results of SPF show that these essential oils can be employed in sunscreen formulations to protect the skin from sunburn. From the results, it can be concluded that the combined antioxidant and SPF property of GEO and CEO can provide synergistic photoprotective effect or lift up the additional value of the cosmeceutical formulation.

Solar radiation represents a key abiotic factor in the evolution of life in the oceans. In general, marine, biota-particularly in euphotic and dysphotic zones-depends directly or indirectly on light, but ultraviolet radiation (UV-R) can damage vital molecular machineries. UV-R induces the formation of reactive oxygen species (ROS) and impairs intracellular structures and enzymatic reactions. It can also affect organismal physiologies and eventually alter trophic chains at the ecosystem level. In Antarctica, physical drivers, such as sunlight, sea-ice, seasonality and low temperature are particularly influencing as compared to other regions. The springtime ozone depletion over the Southern Ocean makes organisms be more vulnerable to UV-R. Nonetheless, Antarctic species seem to possess analogous UV photoprotection and repair mechanisms as those found in organisms from other latitudes. The lack of data on species-specific responses towards increased UV-B still limits the understanding about the ecological impact and the tolerance levels related to ozone depletion in this region. The photobiology of Antarctic biota is largely unknown, in spite of representing a highly promising reservoir in the discovery of novel cosmeceutical products. This review compiles the most relevant information on photoprotection and UV-repair processes described in organisms from the Southern Ocean, in the context of this unique marine polar environment.

Nowadays, agro-food by-products represent a potential low-cost source of biologically active ingredients which have been paid significant attention as nutraceuticals, medicine, food and cosmetics. In a previous study we evaluated the total sugars, metals and polyphenols of olive mill wastewater (OMWW) from a Cerasuola olive cultivar. In the present work we selectively recovered a sugar and mineral enriched fraction (SMEF) from Cerasuola OMWW by a green adsorption/desorption process. The SMEF was mainly found to be composed of monosaccharides and potassium by HPLC-ELSD and ICP-MS. The in vitro cytotoxicity on human fibroblasts, at different concentrations of the fraction, was investigated by MTT and comet assays. In addition, intracellular reactive oxygen species (ROS) production, apoptosis and cell morphological changes were examined. The physical stability of a formulation containing the SMEF (1% w/w) and its in vivo skin effects were also assessed.Our results highlighted that the SMEF showed a toxic effect at higher concentrations (i.e. cell viability reduction, DNA fragmentation and morphological alterations) well correlated with high ROS levels. Conversely, at low concentrations (0.5% and 1% w/w), no significant changes were observed. For the first time, through stability studies and in vivo tests, we also demonstrated that the SMEF formulation is stable and safe for topical application, since skin hydration improvement without negative effects was observed after 7 days of its use. Therefore, the SMEF has great potential to be used for cosmeceutical applications.

BACKGROUND: Saffron (Crocus sativus L.) has a long history of use as a food additive and a traditional medicine for treating a number of disorders. Prominent bioactives of saffron are crocin, crocetin and safranal. OBJECTIVE: The aim of this study was to carry out an extensive patent search to collect information on saffron bioactives and their derivatives as therapeutic and cosmeceutical agents. All patents related to the area of interest published globally till date have been reviewed. Moreover, a recent synthetic biology approach to cost effective and consistent production of saffron bioactives has been highlighted. METHODS: A patent search strategy was designed based on keywords and concepts related to Crocus sativus L. and its bioactives- safranal, crocin and crocetin in combination with different patent classification codes relevant to the technology areas. This search strategy was employed to retrieve patents from various patent databases. The patents which focused on therapeutic or cosmetic applications and claimed compositions comprising crocin, crocetin or safranal as the main active component were selected and analysed. RESULTS: Maximum patenting activity was noticed towards the use of these bioactives in the treatment of neurological disorders followed by multiple uses of the same compound, use in treatment of metabolic disorders and use as cosmeceuticals. Interestingly, there were no patent records related to use of these bioactives in treating infectious disorders. CONCLUSION: Our patent analysis points out the populous and less explored uses of saffron bioactives and areas where there is further scope for research and growth. Recently developed synthetic biology approach is contributory in improving availability, consistency and cost effectiveness of saffron bioactives.
