Composition for strengthening skin barrier and resisting aging as well as preparation method and application thereof

The invention belongs to the technical field of cosmetics, and discloses a composition with skin barrier strengthening and anti-aging effects as well as a preparation method and application thereof. The composition with the skin barrier strengthening and anti-aging effects is prepared from a monascus substrate, monascus enzyme bacteria and dandelions, wherein the mass ratio of the monascus substrate to the dandelions is (3-15): (1-15); wherein the monascus substrate is a starch-rich substrate raw material used for monascus fermentation, and the inoculation amount of monascus enzyme bacteria is 1-10% of the mass of the monascus substrate. Physical barriers among dandelion plant cells can be broken through rich enzyme systems of monascus, active ingredients can be dissolved out easily, the extraction efficiency is improved, monascus and dandelion can achieve synergistic interaction, the skin barrier is strengthened, the antioxidant activity and the anti-aging activity are improved, and the anti-aging effect is
