The buzz word in skin care products has been Hyaluronic Acid. OK, I will make this short and sweet. For the same reasons why we don't use Glycerin in our products (read my blog on glycerine), we don't use Hyaluronic Acid. Hyaluronic Acid is Glycerine on steriods. So if you really have to have products with Hyaluronic Acid in them, just use Glycerine. You'll save a ton of money, but I don't know howt your skin will feal about it.
