[0005] Chinese patent CN 105193882 A discloses a kenaf extract and its cosmetic composition and its application. It is recorded that 85-95% ethanol is used to extract the kenaf root, and the obtained kenaf extract is used in cosmetics and medicines. However, there is no record of relevant research on kenaf leaves
However, in the prior art, the whitening emulsion emphasizes that the addition of natural plant ingredients will lead to poor stability, uniformity and poor texture of the emulsion. Therefore, a kind of ingredient is prepared, which naturally has a better whitening effect and firming effect, and has a uniform and stable texture. Good skin care lotion is particularly important
