A) The indication. In the video, it says "creases and wrinkles around the mouth". This is broader than the actual indication of nasolabial fold winkles.
B) The whole "natural is better" BS. First, it is not 100% from the patient (see the label reference below). Second, the other leading treatments are also "natural".
I would also take issue with the argument that "natural" implies "safer" is obviously garbage, but that may or may not be considered a factual claim.
As to LaViv being natural:
. Severe Hypersensitivity Reactions Serious hypersensitivity reactions, including anaphylaxis, can occur in patients with known hypersensitivity to the ingredients in LAVIV. Do not use LAVIV in patients allergic to gentamicin, amphotericin, dimethyl sulfoxide (DMSO), or material of bovine origin.
