However, the extraction of these components is more technical because it involves genetic engineering. As we all know, genetic engineering technology has developed rapidly in 2 1 century, such as cloning sheep, cattle and even the United States. Genetic engineering has not only brought revolutionary breakthroughs to biopharmaceuticals themselves, but also to neighboring disciplines including the beauty industry.
These components are difficult to extract and very small, so biological researchers copy a large number of effective DNA fragments outside the human body through cloning technology. Of course, these production environments are very strict and must meet the national GMP standards.
Although the effect of polypeptide skin care products will not be as magical as scientific experiments, after all, we are not mice. As the upstairs said, the cosmetics are still not up to the ideal level, just involving the edge. But this makes the effect of biological polypeptide skin care much higher than that of traditional skin care products, and the price is also high. It can be said that biological beauty must be the future development direction of cosmetics, and brands such as L 'Oré al have begun to invest heavily in research and development.
Another point is that peptide can be absorbed by skin, depending on its molecular weight. There are different opinions about how much can be absorbed online. Strictly speaking, 1000 dalton is easily absorbed by the skin. If it exceeds 1000 dalton, you need to use instruments, such as ultrasonic instruments. There is also a popular "microneedle", and there is also an injection, that is, subcutaneous injection.
To sum up, what we don't know can't be killed with a stick. Why the world has developed so much is because it conforms to the development trend and is far from the key point. To tell the truth, we really should popularize scientific knowledge, otherwise, there will be many blind spots.
