The relationship between clinical severity, the hydration state of the skin surface as assessed by a conductance with a 3.5 MHz high frequency impedance meter, and the amino acid content of the stratum corneum (SC) of six patients with ichthyosis vulgaris and 30 elderly persons with varying degrees of xerosis was investigated. With an increase in the severity of xerosis the SC showed a decrease in hydration and in its extractable amino acid content. There was a significant correlation between… 
Decreased hydration state of the stratum corneum and reduced amino acid content of the skin surface in patients with seasonal allergic rhinitis
Functional studies of the stratum corneum in the mid‐portion of the flexor surface of the forearm of 49 skin lesion‐free patients with allergic rhinitis to Japanese cedar pollen in early spring suggest that the SC of the patients with ARD has functional deficiency in water‐holding capacity.
Pruritus and Hydration State of Stratum corneum in Hemodialysis Patients
Water content in the stratum corneum was reduced in hemodialysis patients, but did not correlate with the severity of pruritus, according to a skin surface hygrometer test.
Study on the Relationship between Skin Dryness and Amino Acids in Stratum Corneum
It could be monstrate that amino acid contents of stratum corneum are closely linked with skin barrier and moisturizing function, providing an important and fundamental methodology for the study of amino acids in skin physiology.
Relationship between NMF (lactate and potassium) content and the physical properties of the stratum corneum in healthy subjects.
Changes in the physical properties of the SC induced by the extraction ofNMF were equivalent to the changes that took place from summer to winter, demonstrating the important role of NMF in thePhysical properties ofThe SC in healthy subjects.
Effects of xerosis and ageing on epidermal proliferation and differentiation
Dry skin showed significant changes in the epidermal expression of basal and differentiation‐related keratins, and a premature expression of involucrin irrespective of age, which was significantly decreased in aged/normal compared with young/normal skin.
Electrical measurement of moisturizing effect on skin hydration and barrier function in psoriasis patients
The data suggest that electrical capacitance and TEWL may be useful in the evaluation of the effect of a moisturizer on the hydration status and barrier function of psoriatic skin.
The Acidic Milieu of the Horny Layer
Changes in the pH and the organic factors influencing it appear to play a role, not only in the pathogenesis, prevention and treatment of irritant contact dermatitis, but also of atopic dermatitis and ichthyosis and in wound healing.

Despite the decreased water content of the SC, elderly people can live without any inconvenience even when they expose the facial skin to the dry environment of winter, because there take place sebum excretion and non-apparent sweating by comparison with the skin of the sun-protected areas such as the trunk and limbs that easily develop xerotic changes in cold seasons.
Increased carbonyl protein level in the stratum corneum of inflammatory skin disorders: A non‐invasive approach
Data suggest the involvement of oxidative modification of the SC protein, at least in part, in generation of xerotic skin in inflammatory skin disorders as well as dry skin in healthy subjects.


Electron-microscopic changes in xerosis senilis epidermis. Its abnormal membrane-coating granule formation.
The deficient formation of membrane-coating granules leads to the disappearance of the lipid film which surrounds the stratum corneum cells, which could result in an increase in transepidermal water loss leading to the asteatotic scaly strata corneum seen in the skin of patients with xerosis senilis in winter.
Evaluation of the skin surface hydration in vivo by electrical measurement.
The highly hygroscopic nature of the stratum corneum is demonstrated, lesser hydration on the extremities that on the trunk, the decreased water-holding capacity of scaly lesions despite the increased transepidermal water loss, and the water supplying ability of skin emollients are demonstrated.
Histidine-rich protein as a possible origin of free amino acids of stratum corneum.
The results strongly suggest that the free amino acids and/or their metabolites of the stratum corneum might be the final products of a degradation of the histidine-rich protein.
The results presented in this paper confirm the published observations by others that the hygroscopic water‐soluble substances within the corneum are responsible for much of the water binding ability of the horny layer and propose that it is the cell walls which make up the lipid containing semi permeable membrane system.
Ichthyosis vulgaris: identification of a defect in synthesis of filaggrin correlated with an absence of keratohyaline granules.
It is demonstrated that the structural proteins, profilag Grin and filaggrin, are reduced or absent in 5 patients from 2 pedigrees with ichthyosis vulgaris, and this biochemical abnormality correlates with the morphologic reduction in the amount of keratohyalin, and with the clinical severity of the disorder.
Time‐course labeling of epidermal proteins was examined by sodium dodecyl sulfate‐polyacryl amide gel electrophoresis (SDS‐PAGE) and radioactivity was measured in the following three epidersmal fractions.
