What is a live yeast?
Active yeast is a kind of "living" nutrient, which contains extremely rich active substances and has a good effect on skin repair and regeneration. Because live yeast has its own life characteristics, it will die if the temperature is too high, which requires a high storage environment. Moreover, the life cycle of live yeast is short and the production cost is expensive, so Dolly is used to make high-nutrition regenerated skin care products.
When 1% live yeast is added to general cosmetics, its value will be increased by 5~ 10 times. At present, most cosmetics containing live yeast on the market are imported, and the prices are all above 200 yuan/bottle.
Pitera, the patent component of the famous brand SK-II, is a liquid extracted by a special yeast named saccharomycopsis during fermentation. But Pitera needs sodium hydroxide, polytetrafluoroethylene and sodium benzoate to be used together. This extract needs activation to be effective, and the yeast activity for skin care products is generally 30%.
The benefits of live yeast to skin 1. Live yeast exists as a normal flora of skin, which inhibits the reproduction of harmful flora and protects the balance of skin flora from being destroyed, thus fundamentally maintaining skin health. 2. The live yeast itself has activity, which can quickly drill into the skin and devour deep dirt and oil stains, open the skin nutrition channel, and spit out nutrients and protein for the skin to absorb, which also doubles the skin's absorption capacity for other skin care products. 3. After living yeast enters the skin, it brings in the nutrients needed by the skin, activates and repairs skin cells, accelerates skin metabolism, stimulates collagen secretion by collagen mother cells, and restores skin elasticity. 4. Live yeast can inhibit the formation of mannan pigment to a certain extent, thus slowing down the formation of skin spots.
Objective evaluation of live yeast
About the strain itself
Regarding the fusion of three bacteria, it is difficult to control how anaerobic bacteria and aerobic bacteria survive without being polluted by miscellaneous bacteria. Unless some bacteria are put into a dormant state, such as making them spores, how can they be activated and play a role in the face as advertised? The activation and dormancy of bacteria are not easy to complete under family conditions! Moreover, from the perspective of two-year validity period and domestic commissioned production, it is impossible to keep the strains from being polluted!
About preservatives
If there is no preservative, how is it preserved for three years?
About detoxification
In fact, modern detoxification products are basically gimmicks. Even many businesses use allergic reactions to call detoxification. Where will the poison on your face go?
