With the continuous improvement of living standard, people are pursuing healthy and white skin, so that the demand of whitening compositions is increasing.

Meanwhile, the types of the whitening cosmetics on the market are more and more, the phenomenon that the whitening products on the market are unsmooth is caused, and most products on the market achieve the effects of whitening and brightening the skin through single ways of inhibiting tyrosinase activity, removing oxygen radicals and the like. However, the single whitening principle has limited effect.

Through the search of the existing patent documents, the Chinese invention patent application CN 109662904A discloses a composition with whitening and antioxidant effects, and an application and a preparation method thereof. The composition comprises 0.1 to 3.0 weight parts of water containing factor; 0.01-0.5 parts by weight of polymerization anti-sensitivity factor; 0.1-1.0 weight part of centella asiatica extract; 0.1-3.0 parts by weight of nicotinamide; 0.01-0.3 weight part of alpha-arbutin; 0.1-3.0 parts by weight of tranexamic acid; 0.01-0.1 part by weight of chamomile extract; 0.1-1.0 part by weight of ellagic acid; 0.1-3.0 parts by weight of plant whitening extract; 0.1-0.5 parts by weight of acetylcysteine; 1.0-5.0 parts by weight of hydrolyzed yeast protein; 0.1-3.0 parts by weight of glycosaminoglycan; 0.01-0.1 weight part of aloe extract; 0.1-3.0 parts by weight of green alga extract; hexapeptide-2.1-1.0 weight parts; 0.01-0.5 weight portion of sodium hyaluronate and the like. The invention utilizes different medicinal mechanisms of each component, fully exerts the synergistic interaction effect of each component, and ensures that the obtained composition can accelerate cell metabolism, capture free radicals, inhibit lipid peroxidation, block melanocyte channels, accelerate the falling of melanocytes and the like. However, effective whitening is achieved, the functional components must act on basal melanocytes, and the functional components of the common preparation formulation are difficult to enter whitening target sites. And part of the effective components have irritation to the skin, and the effective active components are easy to generate instability and lose activity.
