The invention discloses a micro-plastic whitening leading-in essence and a preparation method thereof. The micro-plastic whitening leading-in essence consists of the following components in percentage by weight: 4.0%-6.0% of a tropaeolum majus flower extract, 3.0%-6.0% of a brown alga extract, 0.1%-1.0% of an emblic leafflower fruit extract, 0.05%-0.2% of a turmeric root extract, 2.0%-4.0% of a scutellaria root extract, 0.5%-1.5% of hydrolyzed corn proteins, 0.5%-1.5% of hydrolyzed rice proteins, 5.0%-10.0% of yeast beta-glucosan, 0.2%-0.5% of cetostearyl alcohol olivate and sorbitan olivate, 0.5%-1.5% of glyceryl stearate citrate propylene glycol, 3.0%-5.0% of propylene glycol, 3.0%-5.0% of 1,2-pentanediol, 1.0%-3.0% of octyl ethylene glycol, 2.0%-4.0% of Indian vine yellow seed oil, 0.5%-1.5% of tocopheryl acetate, 1.0%-3.0% of sodium ascorbyl phosphate, 0.05%-0.1% of EDTA (Ethylene Diamine Tetraacetic Acid) disodium, 0.2%-1.0% of natto gum, 0.03%-0.07% of citric acid and the balance of deionized water. According to the invention, the defects of a single ingredient, a limited coordination effect, poor durability, easiness in regeneration and the like are overcome, and therefore, the product is safe and can be professionally matched with a micro-plastic machine for use.
