Multitester
Hydration of the epidermis was determined with a
noninvasive technique using an electronic device, Multitester
(CASIO, H-21, India), which measured resistance, based
on the commonly known fact that hydrated skin has less
resistance to current fow than dehydrated skin. The level of
stratum corneum hydration was assessed by measurement f the changes in skin resistance and is referred to as the
galvanic skin response or electrical skin resistance. The
skin resistance reported in ohms with electrodes (size 1
cm2
) was measured after 1, 2, and 3 h and then daily upto
3 weeks for long term study, after application of each
moisturizer, at 1000 khz, 10 mA, AC current according to
the modifcation of Nicander et a
