Taut - tautened?

If something is taut has it been tautened?

I ask because there's an advert(for a face cream) that has
some interesting language use.

\"Discover the first Cellular-Nurturing skincare range, Derma Genesis from
L'Or閍l Paris with Pro-XylaneTM, a new generation, green science molecule
and Hyaluronic Acid. It nurtures cells in the top skin layers. For dewy,
plumped up, younger looking skin. Derma Genesis is suitable for all skin
types.\"

I have no idea what a \"gree science molecule\" is.
