Bonito Elastin Peptide Powder is very, very precious, it is hundreds of times more expensive than collagen peptide, it is extracted from bonito heart bulb arterial bulb. There are very, very few raw materials that can be extracted from a Bonito. At the same time, due to the stable nature of elastin, it is very difficult to degrade, thus increasing the production cost of elastin peptides, which is why real elastin peptides are much more expensive than collagen peptides Much, much, much more reason! At present, studies have confirmed that elastin peptide has the functions of promoting skin damage repair, angiogenesis and promoting the proliferation of fibroblasts (elastin is mainly secreted by these cells)
