Regarding a short-term moisturizing
effect (15, 30 min and 1 hour) as shown in
Fig.3, the CG showed the highest moisturizer
capacity, and significantly different from
CHA, CRW and CB. In addition, there was
no statistically significant difference between
CHA and CRW implying that RW was
comparable to HA. The moisturizing effect
of cream base is due to occlusive effect of
the containing oily material while the PG, G,
HA and RW creams showed the additional
moisturizing effect on the skin due to their
humectancy capability. There were no
significant changes on the untreated areas of
the volunteers during the period of the
experiment.
