the product is quite interesting, the key is the binder for hyaluronic acid and the molecular weight. there is a huge patent problem with hyaluronic acid with most of the patents acqured by JNJ via acquisitions. I would do a search at uspto.gov to see what you come up with, because there could be problems selling it in the US. search for hyaluronic acid and injection or wrinkles
as per fda approval, if the manufacturing is ok it will likly get approved . it is not so easy to make as you might imagine.
I have hard time understanding how it lasts for 8 months or so, again this is the binder property.
many of these "cosmetics" are actually drugs which produce inflammatory conditions of the skin and under biopsy suggest various kinds of pathology to the blinded reader. the inflammatory reaction keeps the area just a little bit inflamed and swollen, taking away the wrinkles, so I do not know how safe it would be for long term use. Although the hyaluronic acid is "natural" it constitutes about 20% of your upper dermis anyway and is made by white cells in response to bacteria infection and other kinds of conditions. it is normally bound with proteins in your body. The binder they have should be a generally recognized as safe compound (GRAS), or they will not get approval unless they have done extensive tox work on the binder
I would wonder what kind of distribution/ production pact they have with the european producers to try to figure out if they will make any money. Who is the parent company?
knowing all of this, there is generally a huge initial enthusiasm for these kind of drugs in the initial two quarters
