Abstract: | The aim of this study was to use two of Vitamin C derivatives, lipophilic ascorbyl palmitate and hydrophilic calcium ascorbate to determine their skin-hydrating effects for the first time. For this purpose, anhydrous cream, gel and w/o emulsion were prepared and applied to the volunteers' inner forearms. A commercial topical preparation containing a known moisturizer, Vitamin E, was also chosen and used for comparison. Moisture contents of the skin were measured by using corneometer. |
