Whitening nano-composition targeting fibroblasts and melanocytes as well as preparation method and application of whitening nano-composition

The invention belongs to the technical field of cosmetics, and particularly relates to a whitening nano composition targeting fibroblasts and melanocytes as well as a preparation method and application of the whitening nano composition. The invention provides a whitening nano-composition targeting fibroblasts and melanocytes. The whitening nano-composition comprises diglucosyl gallic acid, a glycyrrhiza glabra root extract, an olive leaf extract, a hypnea elongata extract, grease, an emulsifier, a co-emulsifier and the balance of water. The whitening nano composition provided by the invention can simultaneously act on melanocytes and fibroblasts in a targeting manner, so as to inhibit a melanogenesis path (MITF), regulate and control an SDF-1 pathway, reduce melanogenesis related enzyme activity, prevent melanin transfer, activate proteasome activity and reduce oxidative inflammation damage and UV stimulation; the nano composition provided by the invention can promote the four functional components to efficie
