Background: Cannabis Sativa seed oil has become more and more popular in cosmetic industry mainly due to the high content of antioxidants and unsaturated fatty acids that are desirable in formulations because they prevent moisture loss and reduce the occurrence of dry skin. Objective: The aim of this study was to determine the effect of Cannabis Sativa seed oil on skin parameters such as hydration and transepidermal water loss. Methods: The in vivo tests on volunteers with combination skin were performed by using non-invasive methods by using corneometer and tewameter. Results: The obtained results proved that Cannabis Sativa seed oil improved skin condition. The transepidermal water loss decreased because the lipophilic components of the oil formulation tend to form an occlusive layer on the epidermis surface. The highest increase in skin hydration was observed after one week of treatment. Conclusion: These results confirmed that Cannabis Sativa seed oil has strong moisturizing properties and can be recommended as a natural based skin conditioning agent.

Body epidermis has an important health function to prevent body dehydration. This research aims to compare Transepidermal Water Loss (TEWL) values between durian seed oil and tengkawang oil. Skin that had been applied with tengkawang oil and durian seed oil lotion were tested for irritation and TEWL values. The tengkawang oil had an acid number of 17 g/mol and contained  8.54 % free fatty acid, while the durian seed oil had an acid number of 6.34 g/mol and contained 2.89 % free fatty acid.  Irritation testing was done using lotion containing 100 % of each oil. TEWL analysis on skin applied with the tengkawang oil lotion after 1 hour showed that the lotion could reduce epidermal water evaporation by 35.23 % compared to the skin condition before treatment.  Epidermal water evaporation reduction at the second, third and fourth hours after the tengkawang oil lotion application was 31.33 %, 33.93 % and 27.9 %, respectively. TEWL analysis on skin applied with the durian seed oil lotion after 1 hour showed that the lotion could reduce epidermal water evaporation by 11.34 % compared to the skin condition before treatment.  Epidermal water evaporation was reduced 14.64 %, 10.53 % and 2.99 % at the second, third and fourth hours after application of the durian seed oil. Based on these results, it can be concluded that tengkawang oil gives better TEWL values compared to durian seed oil.

Abstract Non-invasive methods of skin condition assessment include, among others, the evaluation of transepidermal water loss (TEWL). The aim of the study was to examine whether TEWL values depend on horse breed. The study was conducted on four breeds: “Felin” ponies (FP) (n=16), Polish koniks (PK) (n=15), Polish cold-blooded horses (PcbH) (n=11) and Wielkopolska horses (WH) (n=12). It was found that horse breed influences TEWL values. In the neck region, statistically significant differences were found between PK and FP (p=0.006), and PK and WH (p=0.0005). In the lumbar region, there were statistically significant differences between FP and PK (p=0.0009), FP and PcbH (p=0.0016) as well as between PK and WH (p=0.000037), and PcbH and WH (p=0.0006). In the inguinal region statistically significant differences were found between FP and PK (p=0.0003), FP and PcbH (p=0.0005), PK and WH (p=0.009) and PcbH and WH (p=0.006). In the lip region statistically significant differences were observed between FP and PK (p=0.013) as well as between PK and PcbH (p=0.029) and PK and WH (p=0.009). In the examination of TEWL animal breed should be taken into consideration. The non-significant differences found in three of the examined body regions may suggest that these regions are the most adequate for TEWL assessment.

The transepidermal water loss (TEWL) and the skin wettedness factor (SWF) are considered parts of a key perspective related to skincare. The former is used to determine the loss of water content from the stratum corneum (SC), while the latter is used to determine the human skin comfort level. Herein, we developed two novel approaches: (1) determination of the TEWL and the SWF based on a battery-free humidity sensor, and (2) the design of a battery-free smart skincare sensor device tag that can harvest energy from a near field communication (NFC)-enabled smartphone, making it a battery-free design approach. The designed skincare device tag has a diameter of 2.6 cm and could harvest energy (~3 V) from the NFC-enabled smartphone. A series of experimental tests involving the participation of eight and six subjects were conducted in vivo for the indoor and outdoor environments, respectively. During the experimental analysis, the skin moisture content level was measured at different times of the day using an android smartphone. The TEWL and SWF values were calculated based on these sensor readings. For the TEWL case: if the skin moisture is high, the TEWL is high, and if the skin moisture is low, the TEWL is low, ensuring that the skin moisture and the TEWL follow the same trend. Our smart skincare device is enclosed in a 3D flexible design print, and it is battery-free with an android application interface that is more convenient to carry outside than other commercially available battery-based devices.

Abstract Irritant contact dermatitis is a wide spread occupational skin condition. In addition to generalized protection and teaching schemes, a knowledge about individual risk might add to an improved awareness for hazards. Here, we report on a novel candidate biomarker, which might stage individual susceptibility to irritant skin damage. Subclinical sensitivity was proven in recent studies. As a nano-anatomical measure, it works non-invasively on corneocytes from tape strips. Here, we report on a 7-day course after exposure to sodium lauryl sulphate and compare the novel cell texture index with the classical markers water loss (transepidermal water loss) and natural moisturizing factor. All parameters show a high degree of correlation.
