A skin whitening cosmetic composition comprises a sticopus japonicus extract as an active ingredient. The extracts are extracted by using the hydrophilic solvent. The hydrophilic solvent is the water or the water-soluble ethanol. The extracts are extracted through the reflux extraction or the solvent acceleration extraction. The sticopus japonicus extract is the residual powder after collecting the extract from sticopus japonicus and evaporating the solvent.
