Embodiment 1
[0035] This embodiment discloses a preparation method of stem cell activator for beauty and skin care, which specifically includes the following steps:
[0036] The freshly collected umbilical cord tissue was washed twice with PBS on a 100cm dish, and then cut into 3cm small sections with sterile scissors; the small section was cut longitudinally, 2 arteries and 1 vein were removed, and washed with PBS; with sterile scissors Cut the tissue into pieces, the more broken the better, add DMEM at a ratio of 1:3, add 0.05% trypsin, 200U / ml (or 0.2mg / ml) collagenase IV. Place in a 37-degree incubator, digest for 3-5 hours; then add 25pg / ml hyaluronidase, 37°C, 5-10min; then filter out impurities with a 200-mesh sterile filter, and filter out the cells centrifuge at 1000rpm for 5-10min, discard the supernatant; add FBS or DMEM to wash, then add DMEM containing 10% FBS to suspend MSCs cells, and repeatedly pipette to make cell suspension. Then add it to a 75cm cell culture flask accor...
Embodiment 2
[0040] The stem cell activator obtained in Example 1 was used to detect the contents of EGF (epidermal growth factor), FGF (fibroblast growth factor) and VEGF (vascular endothelial growth factor) using an ELISA kit. Using a commercial detection kit and detecting with a microplate reader, we found that the content of EGF was 0.5 ng / ml, the content of FGF was 0.1 ng / ml, and the content of VEGF was 1 ng / ml.
Embodiment 3
[0042] This embodiment discloses a kind of preparation method of essence, comprising the following steps:
[0043] (1) Configuration of essence matrix: 0.1% hyaluronic acid, 0.2% allantoin, 0.1% hydroxyethyl cellulose, 0.1% dipotassium glycyrrhizinate, according to the volume of 20ml, add in proportion and add deionized water to set Make up to 18ml, stir to dissolve;
[0044] (2) Add 2ml of the stem cell activator obtained in Example 1 to the matrix obtained in step (1), stir evenly and filter to sterilize.
[0045] The essence has the functions of beautifying, anti-aging, repairing cell damage, enhancing skin elasticity, and making the skin softer and more elastic.
