Skin Signature Cream is very similar to other moisturizers from SK-II, including some they sell for almost double the price of this one. What’s the difference? Good question! From a formulary standpoint the differences are shockingly minor and definitely not deserving of such wide swings in prices (though even SK-II’s most inexpensive moisturizer is easily replaced by a similar product from Olay). Like most SK-II moisturizers, this is a blend of water, Pitera (listed as saccharomycopsis ferment filtrate), glycerin, niacinamide, slip agents, thickeners, vitamin E, non-fragrant plant oils, more thickeners, and preservatives. It’s not a bad formula but nothing special and absolutely not worth its price. The price becomes even more disappointing when you consider the jar packaging. This type of packaging won’t keep key ingredients stable during use, and that includes the antioxidants. The formula has merit for normal to dry skin, but so do lots of others that cost considerably less and come in better packaging.
SK-II Skin Signature Moisturizing Cream strengthens Skin Power by helping to restore firming moisture, smoothness and radiance. It contains Vitamin B3, Pitera® and Oli-Vityl, including skin conditioning ingredients which deliver a similar benefit to those naturally in your skin.

Procter & Gamble, as always, is extremely helpful in providing information about their products. In this case it was for their upscale SK-II skin-care line. We certainly can't say that about most companies. We have to acknowledge P&G for having the integrity to share their "inside" details with someone like me, who might be more critical than complimentary. Thank you, P&G!
Regrettably, and we mean that sincerely, we wish we had more positive comments to convey, but alas, we don't. The data provided don't change the reality about skin care and the ingredients that can have an impact on skin. SK-II products are hardly worth the price, especially when compared to Olay Regenerist and Definity (P&G's own drugstore line of skin-care products). In fact, it takes only a quick review of the formulas to note that many SK-II items are very similar to Olay Regenerist items, except that the latter don't include Pitera, the supposedly miracle ingredient in this line. Yet there is minimal research indicating that Pitera is even helpful for skin.
Pitera is the cornerstone of the SK-II line and is present in every SK-II product. Pitera is the trade name for Saccharomycopsis ferment filtrate (SFF), a form of yeast purportedly unique because of the fermenting and filtering process it goes through before being added to these products. As it turns out, many forms of yeast have anti-inflammatory properties and antioxidant properties, including SFF (Source: Journal of Dermatologic Science, June 2006, pages 249–257). Other than that, all of the information about Pitera comes from papers presented at medical conferences, not from published studies. Presenting papers at medical conferences is not at all the same thing as publishing the results of studies. We frequently present papers and information at medical conferences, and we wouldn't offer that material as proof of anything because it isn't. The standards for presenting a paper at a medical conference are very different from the requirements for publication of study results in most medical journals.
To give P&G the benefit of the doubt, even if Pitera is a wonder ingredient, this doesn't explain how it rates when compared with other "wonder" ingredients because there are no comparison studies. Hundreds of ingredients—ranging from green tea to superoxide dismutase, epigallocatechin-3-gallate, eicosapentaenoic acid, beta-carotene, pomegranate, and curcumin to vitamin E, vitamin A, and on and on and on—have stellar reputations, and there's copious documentation to prove it.
Another point to consider: If Pitera deserves the spotlight SK-II shines on it, then P&G needs to change their claims about Olay Regenerist and Definity, and at the very least say that these products are almost as good as SK-II except we left out the Pitera. Ultimately, unless you believe Pitera is the answer for your every skin-care need (because each and every SK-II product contains it, with very few other added extras), there is no reason to waste your time and energy on this line.
