Problems solved by technology

[0003] Most of the existing technologies only consider the choice of humectants to develop moisturizing and moisturizing skin care products. Although they have moisturizing effect to a certain extent, they ignore the influence of other components on overall moisturizing and replenishing water.

Abstract

The invention relates to a water replenishing and moisturizing skin care product comprising a phase A, a phase B, a phase C, a phase D, a phase E and a phase F and discloses a preparation method of the skin care product. Small-molecular hyaluronic acid, middle-molecular hyaluronic acid and macromolecular hyaluronic acid are selected as water replenishing and moisturizing components, and the waterreplenishing and moisturizing effects are realized by use of acting parts of the three components. Meanwhile, through compounding the a Nikkomulese41 O / W type emulsifier and a lecithin type liquid crystal emulsifier, the water replenishing and moisturizing capacity of the skin care product is entirely improved.

Description

technical field [0001] The invention relates to cosmetics, in particular to a moisturizing skin care product and a preparation method thereof. Background technique [0002] The natural moisturizing system in human skin is mainly composed of water, lipids and natural moisturizing factor (NMF). Lipids fill between keratinocytes in a layered form, and their main function is to form a water barrier to prevent water loss. Most lipids are non-polar substances, which can restrict the flow of water in and out of cells and between cells. Due to normal aging, various external stimuli, and environmental damage, the epidermal cells are damaged, and the skin is prone to dryness and dehydration. Conventional small-molecule moisturizers can bring instant hydration to the skin, but they cannot achieve long-lasting hydration. Hyaluronic acid is widely used as the main component of moisturizing skin care products in the prior art. The basic structure of hyaluronic acid is a large polysacch...
