Dermatology Review

To understand why the cream by the sink is not working, you need to know what damaged hands are made of. Layer one — the surface: what you see Rough, tight, red skin across the backs of the hands; splits at the knuckles and beside the nails; fingertips that have gone smooth and shiny and catch on paper. This is where most hand creams work, and they work quickly: water and glycerin plump the outer layer, an emollient smooths the roughness, and within minutes the hand feels better. The relief is real and it is temporary. If your cream feels wonderful and has gone by the time you have dried your hands twice, it was working here.

Layer two — the structure: the barrier that has been stripped Underneath, the outer layer of skin is a wall of flat cells held together by a mortar of lipids — ceramides, cholesterol and fatty acids — and hand skin makes less of it than most of the body while being asked to do far more.9 Surfactants in soap dissolve that mortar, bind to the proteins in the cells, and leave the wall leaking: water escapes faster, and the next irritant gets in more easily than the last one did.5,6,10 That is what the meters are measuring in an irritation study — water loss up, hydration down, for hours or days after a single exposure.11 This is the layer some products work on, with lipids and humectants to rebuild the mortar and an occlusive to slow the leak while it happens.12,13 It is also the layer that can genuinely recover, given four weeks and no interruptions — which, if you wash your hands for a living, you do not get.

Layer three — the root cause: the cumulative irritant cycle One wash does not damage a hand. The damage is arithmetic. Each exposure removes a little more than the skin replaces before the next one, and the deficit accumulates — which is why irritant hand damage is described in the literature as a cumulative insult, and why it takes weeks of protection rather than days of moisturising to reverse.2,10,14 Two things follow, and they decide this review. The first is that a cream has to be there when the water arrives: applied after the wash and gone by the next one, it protects nothing. What counts is substantivity — a film of lipids, silicones or waxes that resists rinsing and is still on the skin several washes later, which is exactly what the workplace protection trials measure and exactly what some products are engineered for.15,16,17,18 The second is that the routine beats the product: the trials that worked used a cream applied regularly through the working day, and the ones that did not were the ones people stopped using.19,20 A cosmetic cannot stop you washing your hands. It can decide how much of the day’s repair each wash takes away.

Protocol Carried out by an independent cosmetic scientist LLM. We set it out in full, step by step, so that you can judge it — and so that you can see exactly what kind of number each figure on this page is. Published data analysed by independent advanced modelling software. Step 1 — The audit In 2026 a modeller analysed published data for 104 hand creams on sale for dry, chapped, cracked or working hands, from supermarkets, high-street pharmacies, department stores, workwear and trade suppliers, the specialist online retailers and the brands’ own sites. Licensed emollient medicines and medical devices, hand washes and sanitisers were excluded. For each product it recorded the full ingredient list, declared percentage, the price per 100 millilitres, the on-pack claims and directions, and the presence of fragrance, listed fragrance allergens, formaldehyde-releasing preservatives and other known irritants. Where a brand declares no percentage, the position of the ingredient in the list was used to estimate its dose. Step 2 — The evidence map For ingredient classes in the six finalists it identified the published human studies of barrier protection and repair — 32 peer-reviewed papers, listed in the appendix — and extracted the effect sizes: the change in hydration and in water loss through the skin, the resistance of the applied film to washing, the effect on irritant-induced damage, and the time to effect. Where a manufacturer has published its own clinical or consumer study, it is logged as a brand claim and reported as a brand claim. Step 3 — The user record It read the reviews on retailer and brand sites and coded each one for four things: how long the relief lasted, stinging on cracked skin, greasiness or slipperiness at work, and whether the reviewer was still using the product after two months. This is not efficacy evidence. It is tolerance and adherence evidence. What this means for how you read the page Every finding below is a projection built from published evidence, not a measurement. Where it writes “is projected to” or “the evidence points to”, that is precisely what it means.

What survives the wash is what counts Every finalist raises hydration within minutes of application. Finding 1 — Protection and repair are two different jobs, and you need both A film that survives washing protects the barrier while it is being attacked; it does not rebuild the mortar that has already gone. Lipids do that — ceramides, cholesterol, petrolatum, the skin’s own moisturising factors — and in the trials the barrier takes weeks to come back, not days.12,13,14 Finding 2 — The tube you will use six times a day Two things from the user record decided this as much as any trial. The first is sting. A formaldehyde-releasing preservative or a strong fragrance on skin that is already split is the difference between a cream applied after every wash and a cream applied at bedtime; the occupational trials that worked were the ones where people kept applying.19,20 The second is grip. Nurses, hairdressers and chefs report abandoning creams that leave hands slippery for ten minutes, which is why the fastest-absorbing product in the review is also one of the most used and why the greasiest is a night-time product for most people.

This is what the published evidence says about each. Glycerin — the best twenty minutes in the review Glycerin draws water into the outer layer, keeps the lipids between the cells in the fluid state they need to be in, and at high concentration produces a measurable reservoir that lowers water loss for days after a course of use.21,22,23 It is in all six finalists and it is the reason every one of them feels good immediately. “Glycerin is the reason hand creams sell,” says the cosmetic scientist model. Petrolatum and mineral oil — unfashionable, but the best evidence on the shelf Petrolatum does two things nothing else on this shelf does as well: it forms a film that slows water leaving, and it works into the outer layer where it speeds the barrier’s own recovery.12 Mineral oil does the first without the second, and it is the base of the most water-resistant formula in the review. Silicones, waxes and starches — the film that survives the tap Dimethicone and dimethiconol leave a water-repellent film; beeswax, paraffin wax and modified starches give it body; acrylate copolymers and hectorite hold it together.15,16 These are the ingredients that industrial barrier creams are built from, and the workplace studies of protective creams — which have found real but modest benefit, and are clear that a cream is no substitute for gloves and fewer washes — are studies of exactly this kind of formula.17,18 Ceramides, cholesterol and the skin’s own moisturising factors — the rebuild Hand skin has fewer sebaceous glands and a thinner lipid supply than most of the body,9 and a stripped barrier does not come back in a day. Physiological lipids — the three ceramides with cholesterol and phytosphingosine — restore the mortar between the cells;13,26 urea at five per cent, sodium lactate, arginine, sodium PCA and the amino acids are the substances the skin itself uses to hold water, and the trials of NMF-based creams show hydration and barrier recovery in dry, damaged skin.27,28,29

If you have read this far, your hands have probably been sore since 2020, and you have probably been told, in one way or another, that the problem is you — moisturise more, wash less, wear the gloves. It is not. The problem is many creams built for skin that gets wet once a day. You now know the three layers, you know what substantivity means, and you know which is still on your hands at wash five. That is more than most people have when they stand in the aisle. Use it. Whatever you choose, apply it after every wash rather than only at bedtime, keep a tube where the sink is, and give it four weeks.
