Trying to Convince Myself that True Beauty Comes from Within.

I was interested reading Mrs G from Derfwad Manor talking about Fads & Trends. She listed a number of current zeitgeist items such as dark chocolate, yoga & a fabulously well-appointed baby-changing wall unit available at Pottery Barn, sadly not available where I come from. Luckily, I am past the stage when I might need one.
But there was one item on Mrs. G's list that I immediately thought that I might need, in fact I KNEW I needed it - Dr. Perricone's Wrinkle-Spack-Filler.
Lately I've been looking at my face & growing glum at the sight of, what my friend Jenny calls, 'Marionette Lines' - lines spiralling around my mouth & grimly heading down to my chin. I don't want to be pumped up with Botox - my students would look at me even more oddly than they do now, so the good Doctor's creme, which promises Immediate Results sounded just the ticket. The only snag was the price - $100. How could I justify spending so much? What if it was just Snake Oil?
A brief internet search about the effectiveness of any Wrinkle-spack filler left me dazed & confused. There's so much conflicting information & some of the prices quoted made the Doctor's stuff look like a Supermarket Line.
Clearly More Research is needed on my part. In the meantime, I'll keep dipping into my well-stocked larder of great smelling 'Clarins' cremes while trying to convince myself that True Beauty Comes From Within.
