Skin aging is a process most often
attributed to UV[1]and also to the use of creams and other cosmetic products low in antioxidant compounds [2]. Photochemically stable
pepo Cucurbita oil can be used as an exogenous cosmetic supplement due to its high
antioxidant content. Incorporated in an agar, media containing a synthetic melanin
solution with added pumpkin oil are subjected to UV light, the aging thus modeled
is followed by the measurement of photoresistance values correlated with chemical
and spectrophotometric analyses. This study confirms that pumpkin oil is highly
effective in protecting the skin, especially the most sensitive skins such as babies’
skin [3] by reinforcing the action
of melanin
