The invention discloses a water-woven net water-locking moisturizing cosmetic and a preparation method thereof. The water-woven net water-locking moisturizing cosmetic is prepared from, by weight, a phase A, a phase A1, a phase B, a phase C and a phase C1, wherein the phase A comprises water and
hydroxyethyl urea, the phase A1 is prepared from
glycerol,
sodium hyaluronate with a weight-average molecular weight of 1000000-1300000 Daltons,
sodium hyaluronate with a weight-average molecular weight of 5000 to 10000 Daltons and
sodium hyaluronate with a weight-average molecular weight of 300000-600000 Daltons, the phase B comprises p-hydroxyacetophenone and a
preservative, the phase C comprises a mixture of water,
butanediol and a
purslane extract, prebiotics,
panthenol,
ceramide, a water-locking
magnet and
fibronectin, and the C1 phase is prepared from water, tetrahydromethylpyrimidine
carboxylic acid and an
ajuga turkestanica extract. According to the invention, through mutual cooperation of an
ajuga turkestanica extract,
sodium hyaluronate with three different molecular structures,
ceramide and a water-locking
magnet, a
skin water absorption channel can be opened, water can penetrate into a
skin basal layer,
intercellular space is filled, water molecules are linked, and a net-shaped water film is formed.
