is this any different than the ordinary hyaluronic acid??????????

Yes, but not by much. This hyaluronic acid claims to be "molecular level", which can penetrate deep into the skin. The Ordinary uses short and long chain HA, which can go deep and mid level of the dermis. So is it different, yes... but is it worth being 300 dollars different...? xD I think thats a rhetorical question. If youre a normal person, just get The Ordinary.
