Background and Objective: Age-related skin changes affect the skin’s structural and functional integrity and reduce the ability of the skin to perform its key barrier functions. Skin breakdown associated with dryness and itch becomes very common and older individuals are at an increasing risk. We aimed to evaluate a daily cleansing–moisturizing routine and conduct a skin assessment for the presence of five underlying skin integrity parameters among aged-care residents. Methods: This small, 6-week evaluation study included four participants over 80 years of age, all of whom were residents at OLC Care, Rocky Point Residence, Beverley Park, NSW, Australia. Skin assessment for the presence of five underlying clinical parameters including itchy skin, dry skin, bruising, skin tears and pressure injuries was conducted for all four participants at baseline and during the evaluation period. Clinical notes were also taken at baseline, during the evaluation and at the post-evaluation. Furthermore, clinical photographs were taken at baseline and after 2–3 weeks of the cleansing–moisturizing routine. Results: Of the four aged-care residents who participated in this evaluation study, all four showed overall improvement in the appearance of the skin with a reduction in severity of the five underlying skin integrity parameters, including itchy skin, dry skin, bruising, skin tears and pressure injuries, where present. Discussion and Conclusions: This case study has produced basic evidence to support a daily cleansing–moisturizing routine (comprising QV cleansers and moisturizers, and/or a protective barrier cream) as it provides moisturizing and protective benefits to the delicate and fragile skin of aged-care residents, where the aim is to reduce skin integrity associated issues.

Background/Objectives: Rice bran oil (RBO) is rich in phytochemical compounds and has many pharmaceutical applications. This work evaluated the regenerative potential of nanofibers incorporating RBO, focusing on their efficacy in tissue engineering and dermatological formulations. The main objective was to investigate the impact of RBO on SK-MEL-28 melanoma cell migration and wound closure through an in vitro healing assay. In addition, the biocompatibility and cell adhesion properties of the nanofibers were examined. Methods: The study employed cell culture techniques and field emission gun scanning electron microscopy (FEG-SEM) investigation. RBO was tested at different concentrations (0.5%, 1%, 5%, or 10%), both in isolation and incorporated into nanofibers. Cell migration was assessed through a wound-healing assay, while cell adhesion to the nanofibers was assessed using FEG-SEM. Statistical analyses were conducted to assess the significance of the findings. Results: Higher cell migration was achieved with 5% (p < 0.002) and 10% (p < 0.05) RBO nanofibers compared to the control and isolated RBO. The biocompatibility study found cell adhesion capability, highlighting the potential of these nanofibers for tissue engineering applications. Conclusions: Our results showed enhanced SK-MEL-28 cell migration and wound closure with RBO-incorporated nanofibers compared to isolated RBO. Biocompatibility was confirmed, suggesting potential for tissue engineering. Our findings indicate that the incorporation of RBO into nanofibers improves their oxidative stability, which is essential for preserving their phytochemical compounds and their beneficial effects on human skin cells in vitro.

Background/objectives: Ultraviolet-B (UVB) represents a major extrinsic factor in skin cancer development, causing cellular changes that are not yet fully understood. Aquaporins (AQPs) are a family of transmembrane proteins that favor water transport and are involved in several pathways. Nicotinamide (NAM), a vitamin B3 derivate, is a safe molecule able to reduce UVB-induced damages. This study aims to verify whether AQP expression is affected by UVB exposure at different dosages and times and to evaluate NAM’s effects against UVB-induced damages. Methods: A375 cells were exposed to 40, 100, and 200 mJ/cm2 UVB doses and analyzed 0, 1, 18, and 24 h post-irradiation. Results: We found that the 40 mJ/cm2 UVB dose, 24 h post-irradiation, caused the most detrimental effects an overall overexpression and dimerization of AQPs. However, in the presence of NAM 25 μM, the cell cycle was restored, leading to improved cell viability and proliferation, reduced ROS levels, and reduced DNA damage. Moreover, we found decreased AQPs expression and dimerization. Conclusions: Overall, NAM effectively mitigates UVB-induced cellular damage, including AQPs overexpression, and may serve as a protective agent against UVB-related skin damage. Full article

Background: Actinic keratoses (AKs) are epidermal neoplasms with a risk of progression to squamous cell carcinoma. Multiple therapeutic options targeting single or multiple lesions, with varying degrees of clearance, have been described. Objective: Evaluate the number of cycles of 5% potassium hydroxide (KOH) solution required for the resolution of actinic keratosis. Methods: This study was conducted on 261 AK lesions in 29 patients. A cycle of application of KOH was indicated in 28 doses with a subsequent monthly clinical and dermoscopic review for a maximum of three cycles of application. Resolution was determined dermoscopically. Results: Dermoscopic resolution was observed in 203 (77.7%) lesions, obtaining a mean number of cycles for a complete resolution of 2.4. Better results were observed in patients who received three cycles than in those who received one or two cycles (p = 0.003 and p = 0.000, respectively). The most common adverse effect was burning, followed by xerosis (69 and 21%, respectively). Conclusions: The 5% KOH solution represents a promising therapeutic option for the treatment of single lesions of actinic keratosis, with an adequate response and tolerable use profile for patients. Based on our results, we suggest the use of 5% KOH solution in AKs with Olsen clinical classification I or II. Full article

Background/Objectives: As the incidence of melanoma and skin cancer is increasing, awareness campaigns can be a useful tool to prevent these conditions. To optimize these campaigns, it is important to establish what the population really know about photoprotection and how they comply with photoprotection habits. Methods: We conducted a survey on the knowledge, behavior, and attitudes related to sun exposure in the Spanish population across the country. The results were analyzed globally and also differentiating by age between those under 25 years of age and those over 25 years of age. Results: Responses from 12,597 respondents were analyzed. Globally, 97% associate bad sun exposure habits with skin cancer; however, when we analyze the results in more detail, the prevalence of an association between tanning and skin damage and the prevalence of the correct use of sunscreens and photoprotective attitudes are lower, especially in people under 25 years old. Conclusions: The data from this survey reinforce the idea that dermatologists need to promote greater awareness among the Spanish population regarding both the skin damage induced by solar radiation and the importance of good photoprotection and preventive habits, specifically in men and people under 25 years of age. To our knowledge, this is the biggest survey to date performed in Spain. Full article
