Abstract
The invention provides whitening lotion with a synergistic whitening effect. The lotion is characterized by being prepared from the following components in percentage by mass: 1-3 percent of nicotinamide, 1-4 percent of whitening compound, 0.5-1.5 percent of tangerine peel extract, 0.1-0.5 percent of arbutin, 0.1-2 percent of 1-methylhydantoin-2-imide and 89-97 percent of cosmetic auxiliary matrix. The invention further provides a method for preparing the whitening lotion with the synergistic whitening effect. The lotion can be used for avoiding the phenomenon that skin receives a negative feedback signal (melanin is reduced, and is required to produce massively) since the signal of a certain whitening node is accidentally reinforced, synergistically highlighting the whitening effect on several whitening key points, and enabling the human skin system to harmoniously reduce generation and transfer of melanin by controlling nodes on the whole whitening chain, so that the skin whitening and brightening effect is achieved.

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a whitening skin care lotion with synergistic whitening effect and a preparation method thereof. Background technique [0002] East Asian women have regarded whiteness as beauty since ancient times, and have used many methods for whitening. Such as milk bath and so on. Many toxic substances were even used, such as the early lead and mercury face coverings, which were still used until the last century. [0003] Since modern times, people have developed and used many whitening agents. Currently, one of the most effective skin whitening actives is hydroquinone, but hydroquinone has a small molecular weight, destroys melanocytes, and may induce inflammation. Therefore, hydroquinone is subject to strict regulations in most countries of the world, and its use as a cosmetic ingredient is prohibited. [0004] Rhododendron was once the main whitening active substance of a famous Jap...
