Blue copper peptide interpretation of this sentence, foreign raw material prices in the 18-20 million yuan / kg, the domestic at least 100,000 yuan / kg or more, the price, and the same weight of gold almost. It is really the “gold” of peptides and the “Hermes” of ingredients. Brand in the use of it as raw materials, the cost pressure will increase. The real situation is: most of them are fake blue copper peptide, and even some also use some blue pigment to disguise themselves, hey ~ a little conscience is also added so a little bit of marketing propaganda, so sisters in the purchase must be bright eyes Oh, do not covet cheap ~
Although the blue copper peptide effect multifaceted, comprehensive function, also has excellent potential and upside, but all of its functions can be replaced.
For example, anti-aging and promote collagen, you can use VCVA, or if you want to pursue a more gentle you can look at the composition of the hyaluronic acid or peptide; then, for example, if you want to look at the restorative effect, you can look at the oligopeptide and ceramides ah, people will have a lot of choices, and the price is not very expensive.
