Composition capable of repairing barrier and resisting inflammation as well as preparation method and application of composition

The invention relates to the field of cosmetics, and particularly discloses a composition capable of repairing a barrier and resisting inflammation as well as a preparation method and application of the composition. The composition is prepared from the following raw materials in percentage by volume: 0.1 to 5 percent of bifidus yeast fermentation product lysate, 0.1 to 1 percent of beta-glucan, 0.1 to 5 percent of galactose yeast fermentation liquor and the balance of phosphoric acid buffer salt solution. Compared with the prior art, the raw material components in the composition are greatly reduced, but the skin barrier repairing and anti-inflammatory effects are better, the production cost can be further reduced, and the production rate is increased. The bifidus yeast fermentation product lysate, the beta-glucan and the galactose yeast fermentation liquor in the composition play a synergistic role, and the composition has remarkable skin barrier repairing and anti-inflammatory effects and has excellent appl
