Abstract

Background: Hydrolyzed collagen is a protein obtained from enzymatic denaturation of collagen with a molecular weight of about 10 kDa, and it has been reported to produce anti-aging properties. Delivering hydrolyzed collagen into the dermis becomes a great challenge due to its large molecular weight, so glycerosome, a deformable vesicle containing glycerol as the edge activator, was developed to carry it into the dermis layer. Objective: The study aimed to determine the effect of increasing the concentration of glycerol and hydrolyzed collagen on the characteristics and stability of hydrolyzed collagen glycerosomes. Methods: Glycerosomes were composed of soy lecithin and prepared using a thin film lipid method. The lipid film was hydrated with phosphate-buffered saline pH 5 containing different glycerol concentrations (20% and 40%) and hydrolyzed collagen (2.5% and 5%). Then, characteristic tests and stability tests were carried out. Results: Hydrolyzed collagen glycerosomes had vesicle sizes of 170-180 nm, polydispersity index of 0.253-0.279, zeta potential values of -23.70 to -26.50 mV with deformability indexes of 2.25-3.49. The highest percentage of entrapment efficiency was 85.72%, achieved with a glycerol concentration of 40%. During the stability test at 25°C for 12 weeks, the hydrolyzed collagen glycerosomes did not experience pH and entrapment efficiency changes, but it increased the vesicle size. Conclusion: The use of 40% glycerol produced more deformable vesicles than 20% glycerol in hydrolyzed collagen glycerosomes; however, a formula improvement is required to improve the stability of glycerosomes.

Abstract

Astaxanthin is a potent antioxidant belonging to carotenoid compounds that is mainly produced from green microalgae Haematococcus pluvialis. Astaxanthin is beneficial for skin health as antiaging agent, but has limitations in its delivery through the skin. Astaxanthin could be formulated in nanostructured lipid carriers to improve its efficacy. The purpose of this study was to evaluate the stability and antiaging effectiveness of astaxanthin-loaded nanostructured lipid carriers (ASX-NLCs) with cetyl palmitate and soybean oil as lipid combinations at several ratios of 100:0, 90:10, 80:20, and 70:30. ASX-NLCs were synthesized using a high-shear homogenization technique. ASX-NLCs were characterized and stability evaluated after storage for 90 days. The antiaging effectiveness of ASX-NLCs was evaluated by in vitro release test using dialysis bag for 8 hours, as well as collagen density and fibroblast count evaluation on UV-induced skin aging mice for 28 days. After storage, all ASX-NLCs did not change significantly in organoleptic, pH, and particle size. However, other parameters including polydispersity index, viscosity, and entrapment efficiency experienced significant changes in some formulas. The release test showed that F4 (70:30) gave the highest cumulative release and was significantly different from F1 (100:0). The collagen density of the groups treated with ASX-NLC F3 (80:20) and F4 (70:30) increased significantly compared to the UVB control group, while the fibroblast count did not differ significantly in all groups. Overall, ASX-NLCs containing cetyl palmitate and soybean oil at ratios of 80:20 and 70:30 could improve the antiaging effect of astaxanthin which might be influenced by its better stability and release.

Abstract

Background: Nanostructured lipid carriers (NLC) are topical delivery systems designed to address the challenges associated with active ingredients, such as poor solubility and limited skin penetration. NLCs incorporate surfactants, such as sorbitan monooleate and lauryl glucoside, to stabilize the system, while the addition of soy lecithin as a co-surfactant further enhances NLC stability. A D-optimal design was employed to optimize the NLC components, ensuring that the formulation achieved the desired characteristics. Objective: To determine the optimal NLC formulation. Method: Optimization was conducted using the D-optimal design method. The NLCs were prepared using the high-shear homogenization method with an Ultra-Turrax device. Characterization included measuring the particle size, polydispersity index (PDI), pH, and creaming index. Results: All formulations resulted in homogeneous emulsions with a white color, slight aroma of castor oil, smooth texture, and thick consistency. The particle sizes ranged from 200 to 500 nm, although the polydispersity index was not significantly influenced by surfactants or co-surfactants. All the formulations maintained an appropriate pH range for skin compatibility and product stability. The %creaming index demonstrated that the co-surfactant effectively reduced creaming in the NLCs. Conclusion: The optimal formulation consisted of 0.284% sorbitan monooleate, 3.429% lauryl glucoside, and 0.287% soy lecithin.

Abstract

Background: Quercetin, a potential skin-lightening agent, reduces intracellular and fungal tyrosinase activities. However, its poor water solubility and limited skin permeability hinder its applications. Nanostructured lipid carriers (NLCs), which are composed of biocompatible and biodegradable lipids, enhance drug stability and skin penetration. The lipid type, surfactant concentration, and formulation parameters influence NLC stability. Objective: This study aimed to optimize NLC formulations for quercetin delivery by evaluating their organoleptic properties, particle size, polydispersity index (PDI), and pH.  Methods: NLCs were prepared using 10% total lipids (4% solid and 6% liquid lipids) and surfactant mixtures at varying concentrations via High Shear Homogenization. Initial formulations using myristic acid and castor oil were unstable and underwent phase separation within five days. Results: Substituting the solid lipid with a 1:3 combination of beeswax and cocoa butter produced a stable formulation during storage at room temperature. The lipid and surfactant compositions significantly influenced the particle size and PDI. While the pH remained stable, statistical analysis revealed significant changes in particle size and PDI across the formulations. Conclusion: Optimized NLC formulations for quercetin delivery demonstrated improved stability and potential for effective skin lightening. Further research is warranted to evaluate the in vivo efficacy and scalability of this approach.

Abstract

Antibacterial substances such as thymoquinone, carvacrol, thymol, and p-cymene are found in black cumin (Nigella sativa), a type of herb. This study reviewed 12 recent scientific publications to assess the antibacterial efficacy of N. sativa against clinical pathogenic microorganisms. A comprehensive literature review of in vitro, in silico studies, and applications was conducted. The study found that black cumin extract and oil were more efficient against Gram-positive bacteria such as Staphylococcus aureus than Gram-negative bacteria such as Escherichia coli and Salmonella typhi. The antibacterial activity increased with the concentration of the extract, especially in the polar form (ethanol). Active compounds such as thymoquinone also showed high binding affinity to MRSA bacterial proteins molecularly. The application of N. sativa in the form of ointments, antibacterial textiles, and dental health products also showed good effectiveness. Based on these findings, Nigella sativa has great potential as a safe and environmentally friendly natural antibacterial alternative, although further clinical studies are needed to validate its efficacy and safety.

Abstract

Background: Alpha-lipoic acid acts as a co-antioxidant that may enhance the effectiveness of green tea extract as an antiaging agent in a Nanostructured Lipid Carrier (NLC) system by improving its entrapment efficiency. This combination is expected to enhance antiaging benefits through increased collagen density and fibroblast proliferation in the skin. Objective: This study aimed to evaluate the effectiveness of an NLC formulation combining green tea extract and alpha-lipoic acid as an antiaging agent. Methods: The NLC system was prepared using the high-shear homogenization method with three formulations: F1 (without alpha-lipoic acid), F2 (1% alpha-lipoic acid), and F3 (1.5% alpha-lipoic acid). The efficacy test was conducted in vivo using mice, with observed parameters including collagen density and fibroblast count in the dorsal skin over 14 days. Results: The results demonstrated that F2 and F3 exhibited significantly higher collagen density and fibroblast counts compared to F1, indicating that the addition of alpha-lipoic acid enhances antiaging efficacy. Conclusion: This study confirms that the NLC formulation combining green tea extract and alpha-lipoic acid effectively increases collagen density and fibroblast proliferation, suggesting its potential as a superior antiaging agent compared to formulations without the co-antioxidant.
