You have almost certainly washed your hands with this before you ever bought it. For twenty years Aesop has placed Resurrection Aromatique Hand Wash in the bathrooms of the kind of restaurant that cares about its bathrooms, on the theory that a scent and a bottle could sell a skincare range without a single advertisement, and the theory worked so well that the amber pump became a shorthand for taste. Judged as a signal, the product is one of the great successes in beauty marketing. Judged as skincare, which is what a review has to do, it is a mild hand soap with a beautiful smell, and that is both less and more than the reputation suggests.
Start with the formula, because it is better than the price tag makes cynics expect. There are no sulfates. The cleansing is done by a sugar-derived glucoside crosspolymer in second place, a coconut taurate in fourth and a cocamidopropyl hydroxysultaine between them, which is a surfactant system chosen for mildness rather than cost; the taurate and glucoside are the sort of anionics found in gentle facial cleansers, and the sultaine cushions them and thickens the gel. A castor-oil emulsifier keeps the essential oils dispersed, salt and a glucose dioleate build the viscosity, hexanediol and dehydroacetate preserve. Tocopherol sits at the end. It is a sound, simple, well-judged sulfate-free wash, the kind that foams densely and rinses without the squeak of a bar.
Then the oils. Mandarin peel in ninth place, cedarwood, lavender, sweet orange and rosemary behind it, and limonene and linalool declared at the end. This is the accord: citrus on top, herb in the middle, wood at the base, bright and green and unmistakable. It is also five essential oils in a product used many times a day, and while a hand wash has seconds of contact and rinses off, the two declared allergens are exactly the ones patch-test clinics see most. For most hands this is irrelevant and the scent is a small daily pleasure. For someone with hand eczema, which frequent washing already provokes, a fragranced wash is the wrong tool however mild its surfactants, and the standard advice is unscented.
In use it is very pleasant. One pump produces a rich, creamy foam, the room fills with mandarin and rosemary, and hands rinse clean and comfortable, with none of the tightness that cheaper gels or bar soaps leave after the fourth wash of the day. Paired with a hand balm at night, it keeps hands in good condition through a winter of washing, which is the whole job. It also survives the test that undoes most scented hand washes, the fourth and fifth wash in a cold afternoon, without the knuckles going papery. That is the taurate and glucoside doing quiet work, and it is why the product has stayed in kitchens and on restaurant basins, where hands are washed constantly, rather than being retired to guest bathrooms as a decorative soap. A hand wash that only works twice a day would not have lasted twenty years in that setting, and this one has. The bottle, with its generous pump, sits on the basin looking like the decision it is, and the refill pouch that now ships alongside it answers the fair objection to buying a plastic bottle of soap every couple of months.
What it does not do is anything a fifth-of-the-price sulfate-free wash cannot. It is not antibacterial and does not claim to be, which is correct, since plain soap and twenty seconds is what hand-hygiene guidance recommends. It has no skin-conditioning actives beyond a trace of vitamin E; the softness after rinsing is the surfactant choice, not a treatment. And $49 for 500 mL, in a category where a good fragrance-free hand wash costs a tenth as much, is a price for the smell and the object, which Aesop has never disguised and its customers have never minded.
That honesty is what makes the product easy to assess. It is a luxury soap that is also a good soap, gentle enough to use all day, scented well enough to be the reason a household buys it again, and priced as a small indulgence rather than as skincare. If the bottle on your basin gives you a moment of pleasure a dozen times a day, that is a fair return on a bottle that lasts two months. If you want the gentlest possible wash for reactive hands, or simply clean hands for the least money, the famous amber bottle is not the answer, and a fragrance-free pump from the pharmacy shelf is.
One practical footnote for the people who buy it for the bottle: keep buying the refill. The formula in the pouch is identical, the pouch uses a fraction of the plastic, and decanting it into the amber bottle keeps the essential oils out of the light, which is the only storage condition a product like this cares about.
