Moisturizing effect of cream containing Moringa oleifera (Sohajana) leaf extract by biophysical techniques: In vivo evaluation

摘要

The purpose of this present investigation is to evaluate the moisturizing effects of cosmetic creams containing extract of?Moringa oleifera?leaves (Sohajana) by non-invasive bioengineering techniques. The study was conducted during the winter months (October to January). A total of eleven healthy male volunteers with ages between 20 and 35 years contributed to accomplish this single blind study. The active cream and base were applied twice daily to the face (cheeks) for a period of 12 weeks. The?instrumental measurements were carried out with tewameter and corneometer under a draught-free room, with controlled temperature (18.0 to 20.6°C) and relative humidity (55 to 65%). The results recommended that the assessed outcome was very well accepted, and improved skin hydration and skin barrier function by the test product. There was a significant decrease in skin?transepidermal water loss?(TEWL) and increase in skin hydration achieved when ANOVA and paired t-sample test were applied.
