The influence of water, glycerin, paraffin oil and ethanol on skin mechanics.

摘要: Moisturizers and emollients do not only smooth the skin but also make it more supple. To clarify this effect, short-term influence of tap water, paraffin oil, ethanol glycerin on mechanics was studied. These substances are all common ingredients in moisturizers emollients. Significant changes were seen already after 10 min application. The distensibility hysteresis (creep phenomenon) showed most pronounced changes. Water oil application caused significant (p < 0.03) increases persisted for at least following application, while they disappeared sooner water Application had a negative effect 0.03). Glycerin appears to have slow onset action, with continuing even stopped. induced by appear be similar those oil. study shows that some capable inducing mechanical properties human vivo 10-min suggesting outermost layers epidermis play an important role mechanics.
