..., including cutaneous inflammation, epidermal hyperproliferation, DNA damage, disruption of epidermal permeability barrier and reduction in stratum corneum hydration levels. Because of the negative impacts of UVB irradiation on epidermal functions, great efforts have been made to develop regimens...

..., individuals with obesity display higher transepidermal water loss rate and lower stratum corneum hydration levels, although no association of obesity with epidermal dysfunction has been documented. Results of skin surface pH are controversial. But study demonstrated a positive correlation of BMI with skin...

... with body mass index (BMI) in a large Chinese cohort. Methods and Subjects: A total of 1,405 Chinese aged 21–98 years old were enrolled in this study. Epidermal functions, including transepidermal water loss (TEWL), stratum corneum hydration, and skin surface pH, were measured on the flexor forearm...

..., while another group was treated topically with Hirudoid® cream 30 min after each application of clobetasol propionate. Untreated mice served as normal controls. Transepidermal water loss (TEWL) rates, stratum corneum hydration, and skin surface pH were measured using respective probes connected...

... increases with duration of exposure. This extraction is tied to a remarkably linear increase in the levels and rates of biaxial stress development during drying/hydration cycles. This effect appears to be tied to the total amounts of lipids extracted. Furthermore, striking changes are seen...

... hydration and skin surface pH were measured on the flexural surface of the left forearm in all volunteers. Epidermal biophysical properties were compared among cohorts of subjects with active hand eczema, a prior history of hand eczema and without any history of hand eczema. A total of 650 questionnaires...

... conditions for EDA measurement, and skin hydration is one factor that has a significant influence. It is, however, not known to what extent the ambient humidity influences the recording. This study explored the influence of relative humidity (RH) on EDA levels, and also the responses using a new technique...

...Megan N. Kelchen; Gopi Menon; Patrick Ten Eyck; Donald Prettypaul; Nicole K. Brogden Application of exogenous products, such as creams, to the skin can result in subclinical changes in selected epidermal functions such as transepidermal water loss (TEWL), hydration, redness, and pH; these changes...

Man Previous studies have demonstrated that UVB radiation changes the epidermal permeability barrier and stratum corneum (SC) hydration. It is well known that sun exposure causes erythema, sunburn and melanoma. However...

..., alterations in cutaneous biophysical properties in vitiligo have not yet been well defined. In the present study, stratum corneum (SC) hydration, the skin surface pH and epidermal permeability barrier function in vitiligo were evaluated. Methods: A total of 30 volunteers with vitiligo comprising 19 males...
