The invention relates to the field of cosmetics and provides a co-conveying nano composition of phenylethyl resorcinol. The co-conveying nano composition comprises phenylethyl resorcinol, other skin whitening active components, a nano medicine carrier as well as solvent complex lipid and water, wherein the phenylethyl resorcinol accounts for 0.1-10% of the total mass of the co-conveying nano composition; the other skin whitening active components comprise at least one of an antioxidant, a cutin peeling type active substance, a melanosome transferring inhibition active substance, an anti-glycation active substance and an anti-allergic agent; the nano medicine carrier comprises raw materials of an emulsifier, a Anti-allergic agent and polyhydric alcohols. Due to compounding of different skinwhitening components and carrying of the nano medicine carrier, a remarkable synergetic effect can be achieved, irritation of high-concentration phenylethyl resorcinol can be remarkably reduced, andthe co-conveying nano composition is good in stability, excellent in skin whitening effect, good in water solubility, good in skin permeability and widely applicable to cosmetics.
