Run your palm down your forearm an hour after using this wash and you will understand why it sells. The skin feels smooth, faintly taut, almost polished, in a way that a basic moisturizing wash does not produce, and if you have been told the bottle contains collagen and firms skin, your hand will happily confirm it. That sensation is real. It is also a film of surface protein drying on the skin, and it has exactly as much to do with the firmness of your arm as a coat of varnish has to do with the strength of a table. Understanding the gap between the two is the whole of reviewing this product, because on every other count it is a perfectly sound drugstore body wash.
Start with what it is under the claim. The base is Olay's petrolatum-forward cleansing system, the same one that runs through the brand's core body range: petrolatum in second place above the surfactant, an ethoxylated sulfate softened by cocamidopropyl betaine, and a cationic guar polymer that helps some of the lipid cling to skin as the lather dilutes. That structure leaves a thin occlusive layer after rinsing, which is why skin feels soft rather than squeaky and why several reviewers with dry skin say they reach for less lotion afterwards. It is a good base. Procter & Gamble has been refining it for two decades and it does more for ordinary dry skin than the clear gels priced alongside it.
Then come the two ingredients on the front. Niacinamide, eighth on the list, is the credible one; it has an enormous leave-on evidence base for barrier lipids and tone, and P&G's own work shows a small amount deposits from a wash. That small amount is a mild bonus, nothing more, but it is real. Collagen is ninth, listed without qualification, and here the chemistry gets blunt. Collagen is a triple-helix protein of enormous molecular weight; it does not pass through the stratum corneum in a leave-on cream, let alone during a thirty-second lather, and it has no route to the dermal collagen whose loss makes skin lax. What it does in a wash is form a film. That film is the silky, slightly tightened feel, and it fades within a couple of hours as it flakes and rubs off. Olay's back label makes the modest claim that skin feels firmer, which is defensible in the way that feeling warm after a whisky is defensible. The front of the bottle says firming, and the Walmart reviews say, over and over, that crepey arms look exactly the same.
None of this means the product is bad. It means it is mislabelled by category. As a cleansing wash it does everything the moisturizing version of Olay's range does, with a slightly different scent, a soft powdery floral with a clean musky base, and a distinctive after-feel that many people genuinely enjoy. The lather is thick and generous, especially on the puff the directions recommend, and the twenty-ounce bottle lasts a couple of months of daily showers. Dry shins look less flaky after a week of use with a lotion afterwards, which is the entire, honest scope of what it changes.
The cautions are the ones that apply to the whole family of Olay washes built on this base. Fragrance is sixth on the list, higher than in most of the brand's newer serum-style washes, so it is present in the shower and mild but noticeable afterwards. The preservative system is methylchloroisothiazolinone and methylisothiazolinone, a blend with a well-documented record as a contact allergen, and two dyes, yellow and red, close the list. For untroubled skin that is a non-issue. For eczema-prone, contact-allergic or otherwise reactive skin, it is three good reasons to choose something fragrance-free and preserved differently, and the minority of reviewers reporting itching and rashes are describing exactly that mismatch.
If firmness is actually what you are after, the useful thing this review can do is redirect the money. Skin laxity on the arms and thighs responds, slowly, to leave-on retinoids, to consistent sun protection on exposed skin and to the passage of less time than you would like; a peptide body lotion left on overnight has at least a plausible mechanism. A wash has none, whatever it contains. Use this as the cleanser in that routine and it will do its part well, keeping the skin comfortable and un-stripped so the leave-on step has something decent to work with. Just do not count the wash as one of the steps.
On value, nine dollars for twenty ounces is a low price for a lipid-depositing wash and a fair one for what this delivers, which is soft skin and a pleasant hour of feeling smoother than you are. It is not worth a penny more than the plain moisturizing version of the same base, and Olay, to its credit, does not charge more. Buy it for the feel, understand the feel for what it is, and put the firming budget somewhere it can actually do something.
