Skin barrier function and stratum corneum hydration
Under normal circumstances, epidermis must be as impermeable as possible except for a small amount of water loss to hydrate the outer layers of the SC. Although all living cells require water to function, some “dead” cells also require water to be metabolically active. As it is the case of corneocytes, epidermis must retain sufficient water to (a) hydrate the outer layers of the SC to maintain ...
متن کاملEffect of Skin-To-Skin Contact on Preterm Infant Skin Barrier Function and Hospital-Acquired Infection
BACKGROUND The preterm infants' skin is structurally and functionally immature at birth because of immature stratum corneum barrier function, leading to problems with fluid loses, thermoregulation, and infection. Two parameters of barrier function can be non-invasively assessed: Stratum Corneum Hydration (SCH) and Transepidermal Water Loss (TEWL). Skin-to-Skin Care (SSC) is the proposed indepen...
متن کاملEthnic skin types: are there differences in skin structure and function?
People of skin of colour comprise the majority of the world's population and Asian subjects comprise more than half of the total population of the earth. Even so, the literature on the characteristics of the subjects with skin of colour is limited. Several groups over the past decades have attempted to decipher the underlying differences in skin structure and function in different ethnic skin t...
متن کاملTreatment of Aged Skin with a pH 4 Skin Care Product Normalizes Increased Skin Surface pH and Improves Barrier Function: Results of a Pilot Study
The physiological skin surface pH is just below 5. With age the skin surface pH increases up to 6. An increased pH correlates with reduced barrier integrity/cohesion. The present pilot study assesses possible normalization of an increased skin surface pH of the elderly and improvement of barrier function via application of ≈pH 4.0 skin care products. Baseline skin surface pH was determined in e...
متن کاملSkin pH: from basic science to basic skin care.
The "acid mantle" is a topic not only of historical interest, but also of clinical significance and has recently been linked to vital stratum corneum function. Despite compelling basic science evidence placing skin pH as a key factor in barrier homeostasis, stratum corneum integrity, and antimicrobial defense, application of the acid mantle concept in clinical care is lacking. We review recent ...
