Elle McPherson caught my eye, as she was obviously supposed to, in an ad for Revlon Age Defying Spa Foundation ($13.99). Spa is the latest in a recent flurry of anti-aging cosmetics that going after the baby boomer market. Most of them are the same old same old with some vitamin E thrown in. So I was curious to see if Elle had put her name to something deserving of the claim 'age defying'.

On balance, I would say that Revlon Age Defying Spa Foundation is a like a layer cake. It has a ghastly sythetic topping, some really good things in the filling and then other layers that you should really leave on the side of your plate.

Pretty high up the list is the helpful peptide, acetyl hexapeptide 8. This is one of several peptides that prevent surface muscles from creating expression lines.

And then the yummy filling really gets going with is lactobillus/lemon peel ferment. This is lemon peel with the kind of bacteria that you get in yohurt and the makers of this combo says it is better at controlling tyrosinase than hydroquinone.  Tyrosinase is the essential enzyme in the formation of melanin by converting DOPA to DOPAquinone. Therefore, reducing its activity is a principal method of improving skin tone.

Revlon also gets points for incorporating acai berry (listed as euterpe oleracea), valued for its antioxidant properties. Although not as well researched as blueberry or pomegranate, acai is certainly one of the newest superfruits.

Then there is a layer of silcones, which are toxic and some of which may penetrate the skin, and nylon with a smattering of aluminium, which is a neurotoxin - although the FDA says it is safe for use in cosmetics.

But then it gets fairly good again with some vitamins, aloe, soy proetein, alga in the form of giant bladder kelp (macrocystis pyrifera), mushroom (which contains ergothioneine, an antioxidant amino acid that occurs naturally in the body and is found in high concentrations around cells that are subjected to free radical damage), green tea and morus bombycis (an antioxidant, according to a Chinese study).

Unfortunately, we are back to silicones and such after that. in fact, there are a dozen silicones in this baby. All in all, I've seen worse. I've also seen much better, such as Lorac's foundation - a simpler proposition with a lot less to dislike.
