Perfect base makeup is the guarantee of exquisite makeup.However,the problem of base makeup darkening seriously affects the cosmetic effect,and also troubles many researchers and consumers.In this paper,a basic liquid foundation was chosen as model to explore the darkness reason from the aspects of foundation hue,volatility of emulsification system,and sebum secretion.DEcmc value determined by non-contact colorimeter was used to monitor the process of darkness.It's widely accepted that foundation oxidation is key to darkness.We herein report a new insight into the essential reason of darkness due to the interaction between light and foundation.The red hue of the foundation darkened faster because the human eyes were more sensitive to the color difference of red.The volatility of foundation emulsion system and skin sebum secretion accelerated the foundation darkening process,which was caused by the change of foundation surface structure.Considering the above influencing factors,the formula was adjusted and an improved formula was proposed,which could significantly reduce the process of foundation darkening.
