Objectives: The objectives of the study were to evaluate skin hydration and transepidermal water loss (TEWL), after the application of the test product (Venusia Max Lotion [Paraben, Alcohol, Mineral Oil, and Animal Origin (PAMA)] free). Material and Methods: The study was a single-center, non-randomized, observational study. Test product was compared to control sites after application on volar forearms of women with dry skin. Hydration and TEWL measurements at baseline, after 12 hours, 24 hours and 36 hours of product application were done under the occluded and unoccluded condition. Results: The study was completed with 30 female subjects. Increase in the mean MMSC values was significantly greater on test product site as compared to control site, at all-time points. For TEWL readings over 36 h, when kept occluded and unoccluded, respectively, there were no significant differences in TEWL readings between the test product site and control site at any time points. Conclusion: The test product, Venusia Max Lotion (PAMA free), can be useful in maintaining the skin barrier properties and significantly improving skin hydration in individuals with dry skin or dry skin-related conditions.

Irritant contact dermatitis (DKI) is a non-immunologic skin inflammation reaction caused by contact with irritants. A janitor is a worker who does a lot of wet work that will repeatedly contact with irritants such as acids, bases, detergents, soap, water, solvents, etc., so that there will be damage to the skin barrier function that starts with loss of the lipid layer and Natural Moisturizing Factor (NMF) so it will reduce skin hydration levels and increase TransEpidermal Water Loss (TEWL). This makes the skin condition becomes dry and the skin defense decreases so that it is easier for DKI. The purpose of this study was to determine the description of skin hydration levels and the incidence of irritant contact dermatitis in janitors at Tarumanagara University. This research is descriptive with a cross-sectional design. A total of 60 people from the janitor became the subject of research. The level of skin hydration is measured by a chronometer. The incidence of DKI in the cleaning staff at Tarumanagara University was 10%, the level of skin hydration in the janitor at Tarumanagara University found hydration levels of dry skin on the right palm (76.7%), left palm (76.7%), back of the hand right (56.7%), and back of the left hand (56.7%). In subjects who experience DKI, levels of hydration of very dry skin on the palm (left-right) and hydration of dry skin on the back of the hand (left-right), and the factors that influence the occurrence of DKI are: gender (female), frequency of washing hands with soap per day, frequency and duration of contact with toilet and floor cleaning products per day and the use of personal protective equipment (PPE), and so it is recommended that cleaners always use PPE when working to prevent DKI and use moisturizers on dry skinABSTRAK:Dermatisis kontak iritan (DKI) adalah suatu reaksi peradangan kulit non-imunologik yang disebabkan oleh kontak dengan bahan iritan. Petugas kebersihan merupakan pekerja yang banyak melakukan pekerjaan basah yang  akan kontak berulang dengan bahan iritan seperti asam, basa, detergen, sabun, air, pelarut, dll, sehingga akan terjadi kerusakan fungsi sawar kulit yang dimulai dengan kehilangan lapisan lipid dan Natural Moisturizing Factor (NMF) sehingga akan menurunkan  kadar hidrasi kulit dan meningkatkan TransEpidermal Water Loss  (TEWL). Hal tersebut membuat kondisi kulit menjadi kering dan pertahanan kulit menurun sehingga lebih mudah terjadi DKI. Tujuan penelitian ini untuk mengetahui gambaran kadar hidrasi kulit dan kejadian dermatitis kontak iritan pada petugas kebersihan di Universitas Tarumanagara. Penelitian ini bersifat deskriptif dengan desain cross sectional. Sejumlah 60 orang dari petugas kebersihan menjadi subjek penelitian. Kadar hidrasi kulit diukur dengan alat korneometer. Angka kejadian DKI pada petugas kebesihan di Universitas Tarumanagara sebesar 10 %, Kadar hidrasi kulit pada petugas kebersihan di Universitas Tarumanagara didapatkan kadar hidrasi kulit  kering pada telapak tangan kanan (76,7%), telapak tangan kiri (76,7%), punggung tangan kanan (56,7%), dan punggung tangan kiri (56,7%). Pada subjek yang mengalami DKI didapatkan kadar hidrasi kulit sangat kering pada telapak tangan(kiri-kanan) dan hidrasi kulit kering  pada punggung tangan (kiri-kanan), dan faktor-faktor yang mempengaruhi kejadian DKI adalah: jenis kelamin (perempuan), frekuensi cuci tangan dengan sabun per hari, frekuensi dan lama kontak dengan produk pembersih toilet maupun lantai per hari dan penggunaan alat pelindung diri (APD), dan sehingga disarankan agar petugas kebersihan selalu memakai APD dengan lengkap saat bekerja untuk mencegah DKI dan menggunakan pelembab pada kulit yang kering

Forearm Skin

Two novel body/face wash gels enriched with emollient ingredients (including dexpanthenol) were developed for the daily care of dry skin. Two similarly designed 2-week studies (N = 42 each) were conducted to assess the biophysical and cosmetic performance of each of the new wash gels in healthy adults with dry skin. Instrumental measurements quantified the effects of the wash gels on stratum corneum (SC) hydration and transepidermal water loss (TEWL) (with and without a previous sodium lauryl sulfate (SLS) challenge) after single and repeated usage. Following single and repeated applications of the face wash gel to facial skin, as well as to dry SLS-undamaged and SLS-damaged skin of the forearm, skin hydration significantly increased. Similarly, after single and repeated usage of the body wash gel to dry SLS-undamaged and SLS-damaged skin of the forearm, skin moisturization increased significantly from baseline; comparisons with control areas provided inconsistent results for SLS-undamaged skin. No effects on TEWL were observed for either product. Both wash gels were well tolerated and the cosmetic performances were appreciated by the subjects. The study results suggest that daily use of the new wash gels was associated with significant skin-moisturizing effects without adversely affecting skin barrier function and repair.

Intercellular Lipid

Keratinocytes undergo maturation during their transit through the viable layers of skin, and then abruptly transform into flattened, anuclear corneocytes that constitute the cellular component of the skin barrier, the stratum corneum (SC). The SC is generally considered to be homogeneous in its structure and barrier properties, and is often shown schematically as a featureless brick wall, the “bricks” being the corneocytes, the “mortar” being intercellular lipid. Previously we showed the outer SC was not homogeneous in its composition, but contained steep gradients of the physiological inorganic elements Na, K and Cl, likely originating from sweat salts. Here we show the innermost corneocytes in human skin are also heterogeneous in composition, undergoing systematic changes in intracellular element concentration during transit into the interior of the SC.Human skin biopsies were taken from the lower leg of individuals with both “good” and “dry” skin and plunge-frozen in a stirred, cooled isopentane/propane mixture.

Although, drugs are required in the various skin compartments such as viable epidermis, dermis, or hair follicles, to efficiently treat skin diseases, drug delivery into and across the skin is still challenging. An improved understanding of skin barrier physiology is mandatory to optimize drug penetration and permeation. The various barriers of the skin have to be known in detail, which means methods are needed to measure their functionality and outside-in or inside-out passage of molecules through the various barriers. In this review, we summarize our current knowledge about mechanical barriers, i.e., stratum corneum and tight junctions, in interfollicular epidermis, hair follicles and glands. Furthermore, we discuss the barrier properties of the basement membrane and dermal blood vessels. Barrier alterations found in skin of patients with atopic dermatitis are described. Finally, we critically compare the up-to-date applicability of several physical, biochemical and microscopic methods such as transepidermal water loss, impedance spectroscopy, Raman spectroscopy, immunohistochemical stainings, optical coherence microscopy and multiphoton microscopy to distinctly address the different barriers and to measure permeation through these barriers in vitro and in vivo.

Stratum Corneum Water Content

Caryocar brasiliense, popularly known in Brazil as “pequi”, is a species widely distributed in the Brazilian Cerrado. The seeds are surrounded by a woody endocarp coated with a yellow fleshy mesocarp rich in oil and vitamin A, whose oil has a useful role in the treatment of skin aging and protection of human skin against UV-induced damage and skin hydration. The aim of this study was to evaluate the effect of cosmetic formulations containing pequi oil (Caryocar brasiliense) on skin hydration, after a single application. Hydration effect assessment was performed by applying the formulations under study (Control – no formulation, vehicle, and vehicle + pequi oil) onto forearm skin of 30 human volunteers. Skin capacitance and Transepidermal Water Loss (TEWL) measurements were analyzed before, and at 1, 2 and 3 hours after, a single application. Evaluation results of a single application of the vehicle containing pequi oil showed an increase in stratum corneum water content, indicating a skin moisturizing effect. Results of the evaluation of immediate effects of TEWL demonstrated that the vehicle containing pequi oil significantly increased skin moisture during the 3 h evaluation period. The formulations containing pequi oil showed clinical efficacy, increasing stratum corneum water content and enhancing skin barrier function.

Medical Compression Stockings

Background and Objective: Although compression therapy is a very effective therapy in reducing stasis-induced complaints, the wearing comfort is not always as requested. Most frequent problems are dryness of the skin and itching. This randomized, cross-over trial investigated 33 healthy participants and compared 2 different medical compression stockings: conventional stockings (type A = MCS) versus compression stockings with integrated care emulsion (type B = MCS-SkC). Methods: Participants were divided into 2 cohorts. Both compression types were worn one after the other, 1 week each. The cohorts were named according to the sequence of the wearing periods (cohort AB/BA). Primary outcome: skin hydration. Secondary outcomes: transepidermal water loss (TEWL), skin roughness, leg volume, interface pressure, and questionnaires about stasis-induced complaints and wearing comfort. Results: Skin hydration: significant reduction after wearing MCS in both cohorts (p < 0.001); preservation of skin moisture after wearing MCS-SkC (p = 0.546 and p = 0.1631). TEWL: significant increase after wearing MCS (p = 0.007 and p = 0.0031); significant reduction by wearing MCS-SkC (p = 0.006 and p = 0.0005). Skin roughness: significant increase after wearing MCS (p = 0.0015 and p = 0.010), and nonsignificant decrease of skin roughness after wearing MCS-SkC (p = 0.933 and p = 0.4570). Leg volume: significantly reduced with both stockings (p = 0.004 and p = 0.0047). Regarding stasis-induced complaints, both stockings achieved good results. Conclusions: Both compression stockings are appropriate to reduce leg edema and minimize leg symptoms. MCS-SkC helps to obtain the natural skin barrier function in preserving the epidermal water content and reducing the TEWL.

<b><i>Background:</i></b> Ablative fractional carbon dioxide laser (AFCO2) resurfacing causes transient skin barrier disruption characterized by decreased skin hydration and increased transepidermal water loss (TEWL). Snail Soothing and Repairing (SSR) cream, containing several glycoproteins with potential antimicrobial and antioxidant effects, may benefit skin hydration promotion after the laser treatment. <b><i>Objective:</i></b> To evaluate the efficacy and safety of SSR cream in skin hydration promotion after AFCO2 resurfacing. <b><i>Method:</i></b> The study was a double-blinded, split-face, placebo-controlled trial in participants aged 18–50 years with atrophic acne scars on both cheeks. After AFCO2 resurfacing, participants applied the product or placebo on either cheek twice daily for 14 days. Corneometry, TEWL, colorimetry, and clinical assessments (edema, erythema, crusting, pruritus, and tightness score) were evaluated at baseline, day 7, and day 14 after AFCO2 resurfacing. <b><i>Results:</i></b> From 22 participants in the study, the SSR cream-treated sides showed significantly higher corneometry levels than placebo-treated sides at day 14 (<i>p</i> = 0.033), while TEWL and colorimetry levels were not different at any study visits. Pruritus and tightness scores of the SSR side were lower, but not significant, than the placebo. Other clinical assessments (edema, erythema, and crusting) showed similar results. No significant adverse events took place. <b><i>Conclusion:</i></b> The SSR cream significantly improved skin hydration, highlighting skin barrier restoration after AFCO2 resurfacing, with a good safety profile.

Plants of the genus Wikstroemia are traditionally used to treat inflammatory diseases like bronchitis and rheumatoid arthritis. In the present study, the anti-atopic effects of an EtOH extract of Wikstroemia dolichantha (WDE) on oxazolone- and DNCB (2,4-dinitrochlorobenzene)-induced dermatitis in mice were investigated. Both ears of BALB/c mice were exposed to oxazolone, and dorsal skins of SKH-1 hairless mice were sensitized with DNCB to induce acute eczematous atopic skin lesions. 1% WDE was applied daily to oxazolone- and DNCB-induced AD mice for two or three weeks, respectively. Total IL-4 and IgE concentrations in serum, transepidermal water loss (TEWL) and skin hydration were assessed. High-performance liquid chromatography/mass spectrometry (HPLC/MS) was used to determine the composition of WDE. Dermal application of 1% WDE grossly and histopathologically improved oxazolone- and DNCB-induced AD skin symptoms. Epidermal thickness and mast cell infiltration were significantly lower in animals treated with WDE than in vehicle controls. Furthermore, in addition to reducing DNCB-induced increases in serum IL-4 (interleukin 4) and IgE (immunoglobulin E) levels, WDE also decreased TEWL and increased skin hydration (indicative of improved skin barrier function). The four flavonoids taxifolin, aromadendrin, padmatin and chamaejasmine were tentatively identified in WDE by HPLC-DAD/QTOF-MS. The above results show WDE protected against oxazolone- and DNCB-induced AD in mice by down-regulating the TH2-associated cytokine IL-4 and improving skin barrier function and suggest WDE might be useful for the management of atopic dermatitis.
