Abstract


Purpose: To formulate stable water in oil (W/O) emulsion containing hydroalcoholic crude extract of Ziziphus mauritiana check for this species in other resources leaves for skin rejuvenation.
Methods: Placebo (base) without any plant extract and formulation with 4 % Ziziphus mauritiana extract were prepared by mixing. Samples of the emulsions were subjected to varying storage conditions, i.e., 8, 25, 40 oC and 40 oC + 75 % relative humidity for a period of 4 weeks to predict their stability. During this period, stability parameters, including liquefaction, phase separation, color, electrical conductivity, centrifugation and pH were monitored at specified time intervals. Skin rejuvenation was evaluated using 13 healthy human volunteers over a period of 8 weeks. During this period, various skin parameters such as erythema, melanin level, moisture content, elasticity and sebum content of the skin were evaluated at specified intervals.
Results: Both the active formulation and placebo were stable in terms of liquifaction, phase separation and color at all the storage conditions of temperature and humidity. Active formulation showed statistically significant (p < 0.05) improvement in skin melanin as well as in skin moisture and sebum levels, whereas these properties were reduced or even absent in the placebo formulation (p > 0.05). Both active and placebo formulations changed skin elasticity and erythema significantly (p < 0.05).
Conclusion: It is evident from the findings that the leaf extract of Ziziphus mauritiana possesses antiaging properties as well as exert skin lightening, moisturizing and viscoelastic effects on human skin.
