The invention discloses a formula for improving skin nutrition absorption and a preparation method thereof, and belongs to the technical field of skin nutrition absorption improvement. The formula comprises water, sodium laureth sulfate, ammonium laureth sulfate, polydimethylsiloxane, sodium cocamidopropionate, cocamidopropyl betaine, cocamide MEA, sodium PCA, sodium chloride, sodium citrate, polyquaternium-10, guar hydroxypropyl trimethyl ammonium chloride, phenoxyethanol, sodium benzoate, polyquaternium-7, a Chinese torreya seed extract, a dendrobium officinale stem extract, a vitex trifolia fruit extract, a radix gentianae extract, a polygonum multiflorum root extract, polyethylene glycol-14M, citric acid, propylene glycol, carbomer and EDTA-Na2.
