Collagen commonly used in cosmetics is generally derived from fish skin or pig skin, which has poor skin affinity, resulting in low transdermal utilization
On the other hand, collagen will be hydrolyzed by the collagenase contained in the skin and lose its original effect
At present, there are many anti-aging cosmetics added with collagen in the market, but the actual use effect is not ideal, and it is also because of this reason

[0043] The preparation method of skin care composition, comprises:
[0044] Extract preparation steps: add 95vt% ethanol twice the weight of dried Prunus umbelliferae leaves to the dried Prunus umbelliferae leaves, extract for 2 hours under reflux and dipping, repeat 3 times to mix the filtrate, and filter the filtrate through 200 mesh After cloth filtration, add butanediol twice the weight of the filtrate to the filtrate and evaporate, the evaporation temperature is 45-55°C, to obtain the extract of Prunus umbelliferae leaves;
[0045] Mixing steps:
[0046] Phase A raw materials (water, hydrogenated lecithin, polysorbate-20, carbomer, xanthan gum, methylparaben, glycerin, 1,3-propylene glycol, hydrolyzed sodium hyaluronate, sodium hyaluronate) are added In the vacuum emulsification pot, stir and heat up to 80-85°C, stir well and keep warm for later use;
[0047] Phase B raw materials (polydimethylsiloxane, cyclomethicone, shea butter oil, squalane, bisabolol, neopentyl gly...

Abstract
The invention discloses a skin care composition and a preparation method thereof. The skin care composition comprises the following effective components in parts by weight: 1-5 parts of soluble collagen and 1-10 parts of a chimaphila umbellata leaf extract. The preparation method comprises the following steps: an extract preparation step: extracting dry chimaphila umbellata leaves with ethanol toobtain a filtrate, adding butanediol into the filtrate, and performing evaporating to obtain the chimaphila umbellata leaf extract; a mixing step: mixing 1-5 parts by weight of the soluble collagen and 1-10 parts by weight of the chimaphila umbellata leaf extract to obtain a skin care composition. In the composition, the chimaphila umbellata leaf extract can inhibit activity of collagenase, delaydecomposition of collagen and promote synthesis of collagen, so that the skin care composition is beneficial to delaying skin aging symptoms.
Description
technical field [0001] The invention relates to a skin care composition and a preparation method thereof, belonging to the technical field of skin care products. Background technique [0002] The determinant of skin aging is the destruction of collagen in the dermis by the internal and external environment. Collagen supports the skin like a spring. Once broken, the dermal tissue will collapse, wrinkles will appear, and the skin will sag and sag. With the growth of age, skin collagen begins to lose at the age of 18-22, and the skin will lose about 40% of collagen at the age of 45-50. [0003] Extensive research has been conducted to find a way to prevent and reduce skin wrinkles, and the important role of collagen has been elucidated. The collagen commonly used in cosmetics is generally derived from fish skin or pig skin, which has poor skin affinity, resulting in low transdermal utilization. On the other hand, collagen will be hydrolyzed by the collagenase contained in th...
