I have the driest skin in the world. 

 You probably do too. It's a side effect of living in Utah. Especially in winter, when heaters inside and cold outside suck all the available moisture (not that there's much) out of the air, facial skin crackles, flakes and crinkles. Those are verbs that belong to a breakfast cereal, not your face.

 So I happily accepted an invitation from the Waldorf Astoria Spa Park City in Park City to try one of their latest facial treatments: the "calming" HydroPeptide facial. "Hydro" means "water," right? Certainly a step in the right direction.

What's a peptide? To be honest, I'm still not clear. The word is derived from the Greek word for "digest." (see related words: dyspeptic, Pepto Bismol, Pepsi-Cola.) That didn't help so much but basically peptides are are short chains of amino acid pieces. 

Forget the chemistry. Or look it up elsewhere. Selling phrases that appealed to me were words like "anti-aging," "anti-redness," and "sensitive skin." 

Because the last facial I tried, at a very prestigious spa, sent me to a doc-in-the-box for a course of prednisone to calm down my face's reaction to the calming facial. 

The Waldorf Astoria Spa was originally the Golden Door, and though now it's self-managed the luxury level has been maintained–the plant wall

the flowing water, cozy fireplaces and cushy chairs in the rest areas are nearly as calming as the treatments. And the fact that the facial began with a warm bed and a foot treatment and a couple snorts of rosemary aromatherapy put the icing before the cake. 

Besides blueberry, which is supposed to be a super antioxidant, the succession of soft facial massages treated my skin with globularia (that's a plant) stem cells, peptides, Bentonite clay (that's the greenish clay you see all over Utah and Wyoming landscapes), an eye gel featuring Argan extract, a serum containing the anti-wrinkle peptide, Acetyl Tetrapeptide-33, mandelic acid and more via peels, masks and moisturizers.

Somehow, the mandolin acid does the same thing that alpha-hydroxy acids are supposed to do (everything) without causing the irritation that's a common AHA side effect in people like me. Although when I looked up "mandelic acid," the article seemed to say that mandelic acid is an AHA.

Despite what I've read and despite the information given by my soft-spoken aesthetician, skin care chemistry remains beyond me. I can't tell what's real and what's not, scientifically speaking. 

Anyway, in the end, what matters is how your skin feels. And at the end of the hour-long PepTide treatment, I felt beautiful.
