Squalane (SQ, a saturated, sebum-mimetic hydrocarbon), oleic acid (OA, a monounsaturated fatty acid), and linoleic acid (LA, a polyunsaturated essential fatty acid) belong to the category of “lipids and fats” in cosmetic materials, and are widely employed as skin-conditioning emollients. However, they present differences in UV stress. In this study, we compared their effects on UV-induced oxidative damage, inflammation, and lipid metabolism using a mouse model and human sebaceous gland cells (SZ95). Results showed that 10% SQ did not worsen oxidative damage or inflammation after 6 weeks of UV exposure. In contrast, the 5% and 10% OA/LA groups showed increased skin wrinkling (p < 0.01), epidermal thickening (p < 0.05), and sebaceous gland atrophy. Transcriptome analysis indicated OA/LA upregulated arachidonic acid-related cytokine pathways (PTGS2/IL-1β; p < 0.001). In SZ95 cells, 0.006% OA/LA significantly increased lipid droplet formation (p < 0.001), free fatty acid (FFA) levels (p < 0.001), and pro-inflammatory gene expression (p < 0.001). Conversely, SQ neither promoted lipid droplet/FFA secretion nor induced oxidative stress. These findings suggest that high concentrations of unsaturated fatty acids in skincare may worsen lipid dysregulation and inflammation, while formulations based on saturated hydrocarbons like SQ could provide superior photoaging management by stabilizing skin barrier function.

Aging leads to a decline in skin function due to intrinsic factors (genetics, hormones) and extrinsic factors (sun exposure, pollutants). Type I collagen plays a vital role in maintaining skin integrity and elasticity. As aging progresses, collagen synthesis diminishes, resulting in weakened skin structure and wrinkle formation. This systematic review explores the role of type I collagen in skin aging by summarizing key clinical findings. A systematic search was conducted using PubMed and ScienceDirect as the primary databases, including studies published between 2014 and 2025 that addressed type I collagen and skin aging. Eleven clinical studies were selected following PRISMA guidelines. The results consistently show the decline of type I collagen as a central contributor to dermal thinning, loss of elasticity, and the appearance of wrinkles and sagging. Clinical trials demonstrate that collagen supplementation, particularly from hydrolyzed fish cartilage and low-molecular-weight peptides, enhances collagen production, improves skin hydration and texture, and reduces signs of photoaging. Overall, the evidence emphasizes the critical role of type I collagen in skin aging and suggests that targeted collagen supplementation may serve as an effective strategy to maintain skin structure and combat visible signs of aging.

The first part of the study shows that four commercial sun protection SPF 50 products provide statistically significant (all p < 0.021) protection by reducing the amount of UV-induced mitochondrial (mtDNA) damage in human dermal fibroblast skin cells (i.e., 320% protection). mtDNA damage has been shown to be an effective and reliable biomarker of skin damage and plays a key role in the ageing process. The second part of the study investigates a sub-set, namely two of the four commercial sun protection products. Both products significantly protect (both p < 0.014) against the longer wavelength blue light induced decrease in a different biomarker, namely the viability of human dermal fibroblast skin cells.

Facial aging is a multifactorial and stratified biological process characterized by progressive morphological and biochemical alterations affecting both cutaneous (Layer I) and subcutaneous (Layer II) tissues. These age-related changes manifest clinically as volume depletion, tissue ptosis, and a decline in overall skin quality. In response to these phenomena, thread lifting techniques have evolved significantly—from simple mechanical suspension methods to sophisticated bioactive platforms. Contemporary threads now incorporate biocompatible polymers and hyaluronic acid (HA), aiming not only to reposition soft tissues but also to promote dermal regeneration. This review provides a comprehensive classification and critical assessment of thread lifting materials, focusing on their chemical composition, mechanical performance, degradation kinetics, and biostimulatory potential. Particular emphasis has been given to the surface integration of HA into monofilament threads, especially with the emergence of advanced delivery systems such as NAMICA, which facilitate sustained HA release. Advanced thread materials, especially those fabricated from poly(L-lactide-co-ε-caprolactone) [P(LA/CL)], demonstrate both tensile support and regenerative efficacy. Emerging HA-covered threads exhibit synergistic bioactivity, stimulating skin remodeling. NAMICA technology represents an advancement in the field, in which HA is encapsulated within biodegradable polymer fibers to enable gradual release and enhanced dermal integration. Nonetheless, well-designed human studies are still needed to substantiate its therapeutic efficacy. Consequently, the paradigm of thread lifting is shifting from purely mechanical interventions toward biologically active systems that promote comprehensive ECM regeneration. The integration of HA into resorbable threads, especially when combined with sustained-release technologies, represents a meaningful innovation in aesthetic dermatology, meriting further preclinical and clinical evaluation.

Garlic is a spice widely used worldwide, but ingestion of garlic can cause unpleasant breath odor that can be offensive in interpersonal interactions. Among several sulfur-containing components of garlic, allyl methyl sulfide is considered the primary causative agent of unpleasant garlic breath and body odor. We discovered that hop cone powder exhibits potent deodorizing activity against allyl methyl sulfide. Oxidation products of the hop bitter acids humulinone and hulupone were detected in a partially purified sample of hop cone powder. Oxidation products of the α-acids cohumulinone and n-humulinone showed approximately 10- and 15-fold stronger deodorizing activity than the parent α-acids, respectively. The deodorizing activity of oxidation products of β-acids was comparable to that of n-humulinone. It is presumed that the oxidation products of hop powder play an important role in the strong deodorizing activity of hop cone powder against allyl methyl sulfide. Full article

Skin aging is a complex process influenced by several factors, including UV exposure, environmental stressors, and lifestyle choices. The demand for effective, natural skincare products has driven research into plant-based oils rich in bioactive compounds. Rosehip oil has garnered attention for its high content of carotenoids, phenolics, and antioxidants, which are known for their anti-aging, photoprotective, and skin-rejuvenating properties. Despite the growing interest in rosehip oil, limited studies have investigated its efficacy on human skin using advanced imaging technologies. This study aims to fill this gap by evaluating the efficacy of cold-pressed Rosa canina seed oil on facial skin characteristics, specifically wrinkles, ultraviolet (UV) spot reduction, and erythema mitigation, using imaging technologies (the VISIA analysis system). Seed oil pressed from R. canina collected from the Băișoara area of Cluj County has been selected for this study due to its high carotenoid, phenolic, and antioxidant contents. The oil has also been analyzed for the content of individual carotenoids (i.e., lutein, lycopene, β Carotene, and zeaxanthin) using HPLC-DAD (High-Performance Liquid Chromatography—Diode Array Detector), along with lutein and zeaxanthin esters and diesters. After the preliminary screening of multiple Rosa species for carotenoid, phenolic, and antioxidant contents, the R. canina sample with the highest therapeutic potential was selected. A cohort of 27 volunteers (aged 30–65) underwent a five-week treatment protocol, wherein three drops of the selected rosehip oil were topically applied to the face daily. The VISIA imaging was conducted before and after the treatment to evaluate changes in skin parameters, including the wrinkle depth, UV-induced spots, porphyrins, and texture. Regarding the bioactivities, rosehip oil showed a significant total carotenoids content (28.398 μg/mL), with the highest levels in the case of the β-carotene (4.49 μg/mL), lutein (4.33 μg/mL), and zexanthin (10.88 μg/mL) contents. Results indicated a significant reduction in mean wrinkle scores across several age groups, with notable improvements in individuals with deeper baseline wrinkles. UV spots also showed visible declines, suggesting ideal photoprotective and anti-pigmentary effects attributable to the oil’s high vitamin A and carotenoid content. Porphyrin levels, often correlated with bacterial activity, decreased in most subjects, hinting at an additional antimicrobial or microbiome-modulatory property. However, skin responses varied, possibly due to individual differences in skin sensitivity, environmental factors, or compliance with sun protection. Overall, the topical application of R. canina oil appeared to improve the facial skin quality, reduce the appearance of age-related markers, and support skin health. These findings reinforce the potential use of rosehip oil in anti-aging skincare formulations. Further long-term, large-scale studies are warranted to refine dosing regimens, investigate mechanisms of action, and explore synergistic effects with other bioactive compounds. Full article

The growing demand for natural anti-aging ingredients necessitates scientific validation of traditional cosmetic materials. Multani Mitti (MM), a clay widely used in South Asian traditional skincare, lacks comprehensive chemical and biological characterization. This study employed a multi-analytical approach to investigate MM’s anti-aging potential through chemical analysis, enzyme inhibition studies, and in silico evaluations. Five commercial MM samples were pooled and analyzed using instrumental neutron activation analysis (INAA) and Gas Chromatography–Mass Spectrometry (GC-MS). INAA revealed silicon as the predominant inorganic constituent (169.3742 mg/g), while GC-MS identified 13 bioactive compounds, with Beta-sitosterol (15.45% area), Docosanamide (12.36% area), and Cyclohexasiloxane (9.80% area) being the most abundant. MM demonstrated significant enzyme inhibition against key aging-related enzymes, with notably strong effects on hyaluronidase (IC₅₀: 18 μg/mL) and tyrosinase (IC₅₀: 27 μg/mL), outperforming standard inhibitors. The antioxidant activity showed moderate effectiveness (IC₅₀: 31.938 μg/mL) compared to ascorbic acid (IC₅₀: 8.5 μg/mL). Molecular docking studies of identified compounds against hyaluronidase (PDB: 1FCV) and tyrosinase (PDB: 3NQ1) revealed Beta-sitosterol and Benzyl-piperazine-carboxamide as the most promising candidates, showing strong binding affinities (−8.5 and −8.6 kcal/mol, respectively) and favorable ADMET profiles. This comprehensive characterization provides the first scientific evidence supporting MM’s traditional use in skincare and identifies specific compounds that may contribute to its anti-aging properties, warranting further investigation for modern cosmetic applications.

Chamomile essential oils (EOs) are widely used in cosmetics for their antioxidant, anti-inflammatory, and antimicrobial properties. Bulgaria, with its long-standing tradition in EO production, provides an ideal setting to examine the influence of species and cultivation practices on oil quality. This study compares the chemical composition and biological activity of EOs from German chamomile (Matricaria recutita L.) and Roman chamomile (Chamaemelum nobile L.), sourced from two major Bulgarian producers—Bulgarska Bilka Ltd. and Kateko Ltd. (Plovdiv, Bulgaria). Gas chromatography–mass spectrometry (GC–MS) profiling revealed species- and producer-dependent differences. German chamomile EOs were rich in β-farnesene, chamazulene, and bisabolol oxides, whereas Roman chamomile EOs were dominated by isobutyl angelate and related esters. Antioxidant activity, assessed via the ABTS assay, was higher in German chamomile EOs, especially from Bulgarska Bilka Ltd. The oils also showed photoprotective potential, with SPF values of 26–27 for German and 9–16 for Roman chamomile. Anti-inflammatory activity, evaluated by inhibition of albumin denaturation, was highest in Roman chamomile oils and comparable to that of prednisolone, while German chamomile also showed strong effects. Antimicrobial activity was generally low, with moderate effects observed only against Penicillium chrysogenum and Aspergillus flavus. These findings support the targeted use of chamomile EOs in cosmetics—German chamomile for antioxidant-rich, UV-protective, and microbiome-supportive care, and Roman chamomile for soothing, anti-inflammatory, and fragrance-enhancing applications.

Salak peel extract has various biological properties befitting cosmeceutical applications; however, their practical uses are still limited due to their low water solubility and stability. Encapsulation technology was employed to alleviate these issues. In this work, we presented a simple method to prepare ethosome-encapsulated salak peel extract using green solvents (ethanol and water). For this purpose, we used 95% ethanol to extract salak peel and explored its activities. Results showed that, in addition to anti-oxidant, the extract also showed anti-tyrosinase, anti-inflammatory, and anti-bacterial (against S. aureus) activities. These activities indicate its potential uses in cosmeceutical applications. We further encapsulated the extract in ethosomes using a stirrer and green solvents for the preparation methods. The yielded ethosomes exhibited a size range of 120 to 205 nm, polydispersity index (PDI) of 0.15 to 0.25, and zeta potential of −35 to −60 mV depending on the amount of L-α-phosphatidylcholine used. The highest encapsulation efficiency was approximately 30%. The antiradical capacity and anti-inflammatory activities of salak peel extract were also found to be maintained after the encapsulation process. An in vitro biocompatibility study of the extract after encapsulation was also performed. The results not only indicated good biocompatibility, but also the potential skin-rejuvenating ability of salak peel ethosomes. A stability study was also performed, and the results suggested that these ethosomes were stable at different conditions. With further investigation, salak peel ethosomes, as presented here, can be suitable for cosmeceutical applications. Full article

Prolonged exposure to ultraviolet (UV) radiations represents a significant risk factor and may lead to various skin disorders, premature aging, and an increased susceptibility to skin cancers. Recently, probiotics have emerged as promising candidates for fortifying the skin’s natural defences through their diverse mechanisms. The aim of the present work was exploring the potential of five heat-treated probiotics (Skinbac^TM, Probiotical Research S.r.l., Novara, Italy), as protective agents against UVA and UVB damages on human keratinocyte line (HaCaT) and human skin 3D model (Phenion^® Full-Thickness Skin Model, Henkel AG & Co. KGaA, Dusseldorf, Germany). The protective role toward artificially induced oxidative stress was evaluated by determining the residual viability after UV exposure and analyzing gene expression of markers involved in apoptosis (Tumor protein 53), inflammation/immunosuppression (Interleukin 6), oxidative stress (oxidative stress response enzyme heme oxygenase 1), investigated using quantitative real-time PCR. Additionally, we examined the protective effects of these strains, testing them on Normal Human Epidermal Keratinocytes (NHEK) irradiated with UVC, specifically, evaluating the expression of tight junction proteins, including claudin 1, claudin 4, and occludin, by ELISA. The tested heat-treated probiotics effectively protected from UVA, UVB, and UVC damage on all end points analyzed, revealing their capacity to enhance barrier protection in cases of damage and their potential for innovative skincare strategies centered around probiotic-based formulations for enhanced protection against UV-induced skin damage.

Maintaining the physiological acid–base balance of the skin is critical to preserving the integrity of the epidermal barrier and preventing irritation. This study investigates the short-term effects of natural soaps, prepared using cold and hot processes, on skin surface pH. A double-blind, controlled design was applied to assess changes in pH following application of soap formulations. pH levels were measured in vivo using non-invasive instrumentation at baseline and 2, 15 and 30 min post-application in 41 adult volunteers. The results demonstrated a significant increase in skin pH immediately after exposure to both types of natural soap, with elevated values persisting for up to 30 min. These changes were associated with potential disruption of the skin’s acid mantle and reduced buffering capacity. The findings highlight the importance of pH considerations in the formulation and routine use of natural cleansers. Although natural soaps are often perceived as gentle alternatives, their alkalinity may transiently disturb the skin’s acid–base homeostasis, potentially leading to increased transepidermal water loss and barrier impairment. This study supports the need for reformulation strategies and consumer awareness regarding the physicochemical impact of cleansing agents on skin health. Full article

This study evaluates the efficacy of a novel moisturizing cream using a sodium lauryl sulfate (SLS)-induced skin damage model, supported by advanced imaging with two-photon microscopy (TPM). TPM’s capabilities allow for in-depth, non-invasive visualization of skin repair processes, surpassing traditional imaging methods. The innovative formulation of the cream includes ceramide NP, ceramide NS, ceramide AP, lactobacillus/soybean ferment extract, and bacillus ferment, targeting the enhancement of skin hydration, barrier function, and structural integrity. In SLS-stimulated 3D skin models and clinical settings, the cream significantly improved the expression of key barrier proteins such as filaggrin (FLG), loricrin (LOR), and transglutaminase 1 (TGM1), while reducing inflammatory markers like IL-1α, TNF-α, and PGE2. Notably, the cream facilitated a significant increase in epidermal thickness and improved the dermal–epidermal junction index (DEJI), as observed through TPM, indicating profound skin repair and enhanced barrier functionality. Clinical trials further demonstrated the cream’s reparative effects, significantly reducing symptoms in participants with sensitive skin and post-intense pulsed light (IPL) treatment scenarios. This study highlights the utility of TPM as a groundbreaking tool in cosmetic dermatology, offering real-time analysis of the effects of skincare products on skin structure and function.

This study investigates the impact of emulsifier substitution and booster concentration on sunscreen characteristics, including physical properties, the sun protection factor (SPF), and sensory attributes. The impact of substituting Polysorbate^® 80 with Beautyderm^® K10 as an emulsifier in sunscreen formulations, along with the effect of increasing concentrations of the Sunhancer™ Eco SPF Booster, was thoroughly evaluated. Spectrophotometric methods were used to determine SPF, while texture analysis and rheological measurements assessed physical characteristics. Stability was evaluated using a centrifuge stress test, and sensory analysis was conducted on the top-performing formulation. The results indicated that the choice of emulsifier and booster concentration significantly influenced SPF values and stability. The influence of booster concentration on textural properties was most significant in formulations containing Beautyderm^®. Centrifuge testing revealed phase separation in certain formulations. Notably, the formulations that exhibited the greatest stability were those in which Beautyderm^® was combined with either Polysorbate^® or Span^®. Following the stability test results, the cream formulation containing Beautyderm^® and Polysorbate^® as emulsifiers was further evaluated through sensory analysis. Independent assessors determined that the sensory attributes of the cream did not undergo significant changes even when zinc oxide was added at a concentration of 1% (w/w) to the formulation. These findings underscore the importance of carefully selecting emulsifiers and boosters to achieve high sun protection efficacy, stability, and desirable sensory properties in sunscreen formulations.

Humans are exposed to pollutants daily through various routes, including skin contact. A key concern is the presence of endocrine-disrupting chemicals, which means they can mimic, block or interfere with the body’s natural hormones, in many everyday items, among which are personal care products. We set up a chromatographic method to simultaneously assess the occurrence of nine endocrine disruptors and to verify the compliance with mandatory regulations concerning the potential fraudulent additions of preservatives. A total of twenty-six haircare products were collected and analyzed. The limits of detection ranged from 0.052 μg mL⁻¹ to 1.744 μg mL⁻¹, while the limits of quantification ranged from 0.175 μg mL⁻¹ to 5.815 μg mL⁻¹, respectively. Analyte recovery was between 66% and 87%, demonstrating the accuracy of the method in these target formulations. Even if the recovered quantity of parabens did not exceed the legal limits, the analysis detected bis(2-ethylhexyl) phthalate (DEHP) in 2 real samples and dibutyl phthalate (DBP) in all 26 samples, with concentrations ranging from 151.01 μg/100 g to 1042.58 μg/100 g. Although the European Union regulates the quantity of potentially harmful compounds in consumer goods, repeated use of certain products, such as haircare formulations, could result in chronic exposure to several endocrine disruptors.

Microbiological quality control in cosmetic and pharmaceutical products is crucial for consumer safety. Traditional culture-based detection methods, such as plating on selective media, are time-consuming and may lack sensitivity. Fluorescence In Situ Hybridisation (FISH), a molecular and culture-independent technique, enables rapid and precise microbial identification by targeting specific RNA or DNA sequences with fluorescent probes. In this study, a novel DNA-FISH probe was developed for the detection of Candida albicans in cosmetic formulations. The probe’s specificity was assessed in silico and experimentally using flow cytometry (flow-FISH) on C. albicans and non-target microorganisms, including Pichia kudriavzevii, commonly known as Candida krusei, Saccharomyces cerevisiae, Wickerhamomyces anomalus, Escherichia coli, and Staphylococcus aureus. The probe exhibited 98.9% hybridization efficiency with C. albicans, yielding a fluorescence intensity (FI) of 25,000 (a.u.), while non-target yeasts demonstrated minimal hybridization (4.7%, 2.3%, and 1.9% for C. krusei, S. cerevisiae, and W. anomalus, respectively) and bacteria showed negligible FI. Additionally, the probe’s applicability was evaluated in a tonic formulation, where C. albicans’ hybridization efficiency was slightly reduced to 88.4%, suggesting that formulation components may influence probe performance. Nevertheless, the probe maintained high specificity and efficiency without formamide, a toxic reagent commonly used in FISH. These findings highlight the potential of FISH probes for rapid, accurate, and safe microbial detection, offering a valuable tool for microbiological quality control in the cosmetics industry.

2-aza-8-oxohypoxanthine (AOH) has been shown to improve skin barrier function according to DNA microarray studies of normal human epidermal keratinocytes. This study aimed to evaluate the cosmetic efficacy of AOH in wrinkle improvement. A 12-week clinical trial involved 23 women (mean age 44 ± 8 years), who applied 0.01% or 0.05% AOH lotion to each half of their face twice daily. Skin assessments were conducted before and after application at 4, 8, and 12 weeks by measuring stratum corneum water content using a Corneometer and evaluating wrinkles through image analysis of replicas. Application of the lotion enhanced stratum corneum water content. Use of 0.01% AOH reduced the wrinkle area percentage and maximum wrinkle depth at 8 and 12 weeks post-application, respectively. The 0.05% lotion showed a significant reduction in the wrinkle area percentage and mean maximum wrinkle depth at 12 weeks and a significant decrease in maximum wrinkle depth at 4 weeks. A between-group comparison revealed that the 0.05% AOH lotion significantly reduced mean maximum wrinkle depth compared to the 0.01% AOH lotion at 8 and 12 weeks, indicating a concentration-dependent effect of AOH. Overall, AOH improves wrinkles in a concentration-dependent manner, confirming its efficacy as a cosmetic ingredient for wrinkle improvement. Full article

Natural mineral waters (NMWs) and plant extracts have long been valued for their therapeutic properties and skin benefits. This study investigated, in vitro, the role of five Portuguese NMWs (A-E), combined with plant extracts from five species (Ficus carica L., Rubus idaeus L., Vaccinium myrtillus, Cistus ladanifer and Thymus x citriodorus) as bioactive ingredients. Antioxidant capacity was assessed using the 2,2-Diphenyl-1-picrylhydrazyl (DPPH) method. Cellular biocompatibility was evaluated in fibroblasts (L929) and macrophages (RAW 264.7). Skin-repairing and anti-senescence properties were evaluated in L929 cells through the scratch-wound method and β-galactosidase assay. Superoxide dismutase (SOD) was quantified using a commercial kit, and lipopolysaccharide-induced reactive oxygen species (ROS) were quantified using a fluorescent probe (H₂DCFDA) in RAW 264.7. The results highlighted the beneficial impact of extracts combined with NMWs. An increase in antioxidant capacity of up to 90% was observed in mixtures comprising Ficus carica L., compared with NMWs alone. In contrast, mixtures with Cistus ladanifer showed promising anti-aging potential, with a 40% decrease in senescent cells and a 33% ROS reduction. Rubus idaeus L. extract produced an increase in cell migration capacity (up to 50%), depending on the NMW. This study highlights the potential synergism of natural ingredients with plant extracts for anti-aging. Full article

Cumulative exposure to UV radiation can lead to harmful effects such as skin burns, photoaging, and skin cancer, thus highlighting the importance of using photoprotective formulations. Many sunscreens are vegan and have antioxidant substances to ensure additional photochemoprotective action. We evaluated biophysical, rheological, and sensorial parameters of Face Care Facial Moisturizing Cream^® (P1) and a vegan formulation (P2) by in vitro and in vivo tests. Sun Protection Factor (SPF) was evaluated by Mansur method. Biophysical parameters were analyzed: sebum content, hydration level, transepidermal water loss, erythema and melanin level, skin color, and skin pH. The acceptance profile of the formulations was determined using a 9-point hedonic scale and a 5-point purchase intention test. The SPF values of P1 and P2 obtained by in vitro tests were 25.21 and 12.10, respectively. They also exhibited pseudoplastic and thixotropic behavior, which could contribute to better spreadability and form a protective film. Biometric tests showed an increase in hydration and skin sebum, decreased erythema, and maintenance of skin pH after application of both formulations. The comparison of a commercialized product and a vegan test version showed similar rheological and great acceptance profiles. Therefore, the vegan formulation is a good alternative to reach a different market. Full article
