Abstract

The invention relates to the technical field of cosmetics, in particular to a ceramide composition with a repairing function and a cosmetic. The invention discloses a ceramide composition. The ceramide composition comprises more than three of ceramide EOS, ceramide NS, ceramide NP and ceramide AP. It is accidentally found that compared with single use of one ceramide or two ceramides, the ceramidecomposition has a synergistic effect when the three or more ceramides are combined, all the components of the ceramide composition synergistically repair a multilayer lipid structure of ordered tissue between keratinocytes, a skin barrier is repaired and permeation of irritants is reduced, and therefore, the defensive property of the skin to external stimulation is improved, the water content ofthe cuticle of the skin is further remarkably improved, the water locking capacity of the skin is enhanced, and the problem that the skin becomes red is solved.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a ceramide composition with repairing function and cosmetics. Background technique [0002] As the largest organ covering the surface of the human body, the skin is in direct contact with the external environment and is easily damaged by ultraviolet rays, microorganisms, physical and chemical stimuli. The skin is composed of three parts: the epidermis, the dermis and the subcutaneous tissue, and the outermost structure of the epidermis, the stratum corneum, plays a vital role in the skin barrier. Researchers vividly compare the stratum corneum to a brick wall structure: the stratum corneum cells are likened to the bricks of the wall, which are formed by cross-linking filaggrin and cytokeratin to form an insoluble dense structure; and intercellular lipids Likened to the dust of a wall. Intercellular lipids mainly contain 50% ceramides, 30% cholesterol and 20% free fatty acids....
