Active yeast is a "live" nutrient, rich in active substances, which has a good effect on skin repair and regeneration. Since live yeast itself has the characteristics of life and will die if the temperature is too high, the storage environment requirements are very strict. The survival period of live yeast is short and the production cost is high. Therefore, Dolly the sheep is used to produce highly nutritious regenerative care products.
Generally, adding about 1% live yeast to cosmetics will increase its value by 5 to 10 times. Most of the cosmetics containing live yeast currently sold on the market are imported, and the price is more than 200 yuan per bottle.
Pitera, the patented ingredient of the well-known brand SK-II, is a liquid extracted from the fermentation process of a special yeast called Saccharomycopsis cerevisiae. But Pitera requires a combination of sodium hydroxide, polytetrafluoroethylene, and sodium benzoate. This extract needs to be activated before it can work. The activity of yeast used in skin care products is generally 30%.

About the strain itself
As for the integration of the three bacteria, it is difficult to control how anaerobic and aerobic bacteria can exist without being contaminated by other bacteria, unless some are allowed to The bacteria enter a dormant state, such as turning into spores. But how do they activate and work on the face as advertised? The activation and dormancy of bacteria are not something that can simply be accomplished under home conditions. And simply judging from the two-year shelf life and domestic commissioned production, it is impossible to prevent the strains from being contaminated!
