The invention relates to a skin spray based on deep repair and long-lasting moisture preservation. The skin spray is prepared from antarctic ice brown alga extract, auroral alga extract, arctic draparnaldia extract, jellyfish extract, sea spring water, hydrolyzed lupin protein, fragrant citrus fruit extract, 1,3-propanediol, poly-gamma-sodium glutamate, beta-sitosterol sodium sulfate, tocopheryl linoleate, wild soybean seed extract and other raw materials. Compared with the prior art, the skin spray has the advantages that the varieties and use quantities of the raw materials are strictly regulated, so that the technical formula of replenishing water to the surface layer (cuticle), replenishing nutrients (lipopolysaccharide, protein, microelements and the like) to the deep layer and activating cells meets the skin moisture preservation mechanism better, and the optimized formula design of the ingredients with the moisture preservation barrier and repair synergism is achieved.
