Abstract

The invention relates to a whitening spot-fading composition and an application thereof, and provides a whitening spot-fading facial mask with a remarkable effect. The composition with the whitening spot-fading effect provided by the invention includes the following components: 0.001-0.008% of frozen pear extract and 0.001-0.008% of orychophragmus violaceus extract. Through research, the applicants find that the frozen pear extract has better tyrosinase inhibitory activity than an unfrozen pyrus bretschneideri extract. The frozen pear extract and the orychophragmus violaceus extract have a significant synergistic effect after being compounded; and nutrient ingredients are added to a facial mask, so that playing of the whitening spot-fading effect of the frozen pear extract and the orychophragmus violaceus extract can be effectively promoted, and the whitening spot-fading effect of the facial mask can be obviously improved.

It is generally believed that the abnormal growth of melanin or the uneven distribution of melanin caused by abnormal hormones or ultraviolet rays from sunlight are the main reasons. The metabolic pathway of melanin has been relatively clear: in melanocytes, tyrosine is gradually transformed into true melanin through intermediates such as dopa, dopaquinone, dopachrome, and dihydroxyindole under the action of enzymes such as tyrosinase. ...
