Dermatologist's Verdict

AmLactin Daily Nourish is the body lotion I recommend for keratosis pilaris and rough, dry limbs. Its 12% ammonium lactate pulls water in and loosens the glue holding dead cells on, so the bumps flatten. Wear sunscreen, because it makes you burn more easily. Too strong for the face.

The short versionWhat It Is

AmLactin Daily Nourish Lotion 12% is a fragrance-free body lotion in a 7.9 oz pump bottle, about $13 to $18. It was called Daily Moisturizing Lotion until a recent rename. It is a body lotion, not a face product, and it is sold as a cosmetic rather than a drug.

The active is ammonium lactate at 12 percent, the salt of lactic acid. The base is short — mineral oil, glycerin, cetearyl alcohol, dimethicone. Nothing softens the acid, which is why the lotion is thin, sinks in fast, and stings on cracked or freshly shaved skin.

Where it earns its keepWhat It Treats

Keratosis Pilaris
Keratosis Pilaris
Works well
Keratosis pilaris is a plug of keratin — the protein skin cells are made of — in the opening of a hair follicle. That is why the bumps feel like sandpaper and why scrubbing does not shift them. Ammonium lactate loosens the bonds holding the plugs together so they shed, and the bumps come back within weeks of stopping.
Dry Skin (Xerosis)
Dry Skin (Xerosis)
Good fit
Ammonium lactate is a humectant as well as an acid, so it pulls water into the outer layer while it thins the rough surface. That is why it works on very dry shins when a plain lotion has done nothing.

Don't expect miraclesNot the Best For

Acne
Acne
Barely works
Ammonium lactate is an AHA, so it gets tried on chest and back breakouts. At body-lotion strength it is not an acne treatment, and the base is heavier than acne-prone skin wants.
Eczema
Eczema
Never use
It looks right for dry, itchy skin, but lactic acid burns on a cracked barrier. Settle the flare with a plain cream first.
Sensitive Skin
Sensitive Skin
Poor fit
An acid at 12 percent stings on anything cracked, broken or freshly shaved, and AmLactin says to keep it off open skin. For the same coverage without acid, use Vanicream Moisturizing Cream.

How it feelsTexture

A thin, standard lotion. It pumps out easily and spreads a long way.

It sinks in within a minute and leaves almost no residue, so clothes go straight back on.

There is a faint sour smell from the lactic acid, which most people stop noticing. It stings for a few seconds anywhere skin is cracked or freshly shaved, sharper than people expect from a body lotion.

The house rulesHow to Use AmLactin Daily Nourish Lotion 12%

Where: Body only. Upper arms, thighs, shins, forearms. Not the face.
How much: A thin layer over the area. More does not work faster.
Careful: Alpha hydroxy acids make skin burn more easily, and the label warning covers the week after you stop, so wear sunscreen or keep the skin covered. Not on broken or freshly shaved skin.
What to expect: Smoother in about two weeks, better by four to six. This manages keratosis pilaris; nothing cures it. The bumps return within a few weeks of stopping, so you keep using it.

What's insideAmLactin Daily Nourish Lotion 12%: What It Does in the Skin

A moisturizer has three moves: pull water into the bricks, replace the glue, or seal the wall. This does something a plain moisturizer cannot. Ammonium lactate is a humectant, pulling water into the dead outer cells, and an alpha hydroxy acid, loosening the bonds between them so they shed. The rough surface thins instead of only getting damp.

For keratosis pilaris, keratolytics like this are the mainstay of treatment. Not a cure. The bumps return when you stop.

One fact makes the price look strange: at 12 percent this is the same molecule at the same strength as Lac-Hydrin, which needs a prescription. It cuts both ways, though — Lac-Hydrin was reviewed by the FDA for whether it works, and AmLactin, sold as a cosmetic, was not.

In the skin barrier

PULLS WATER INFILLS THE GAPSSEALS WATER INSEALS WATER IN

Small enough to sink into the bricks, where it swells them with water and holds it there for days.

Waxy solids — not the drying kind of alcohol. They thicken the cream and soften the surface.

A plain, well-tolerated seal over the top of the wall.

A silicone that spreads into a thin film over the bricks. A lighter seal than petrolatum, and what makes a cream feel silky rather than greasy.

The outermost layer, and the one every moisturizer is aiming at. It is dead — flattened cells stacked like bricks, with a mix of fats as the glue between them. That glue is what holds water in and keeps irritants out.

The outer layer, and the only one anything in a jar reaches. It renews itself constantly: a cell made at the bottom takes about a month to reach the surface and flake off. Most of what a skincare product does, it does here.

The living layer underneath, holding the blood vessels, the nerves and the collagen. It is where lasting change happens and it is hard to reach: most of what is sold for the skin never gets this far.

This is how many ingredients are on the label. The more a product contains, the more chances one of them bothers you. That matters most if you have sensitive skin, eczema, or a known allergy. If your skin tolerates most things, a long list is not a problem by itself.

The fine printA Dermatologist’s Concerns

It is a cosmetic, not a drug: the prescription comparison cuts both ways. Lac-Hydrin 12% is an FDA-approved drug, reviewed for safety and effectiveness. AmLactin sells the same molecule at the same strength as a cosmetic — no Drug Facts panel, no FDA efficacy review. Same active, two different regulatory worlds.

Sun sensitivity lasts a week after use: it makes you burn more easily, for longer than you think. The alpha hydroxy acid warning says to use sunscreen and protective clothing while using it "and for a week afterwards." Almost nobody reads that far.

May sting on broken skin: AmLactin's own guidance is to avoid open or cracked skin, and its FAQ says the lotion "will not treat or cure" eczema, psoriasis or rosacea.

The bumps return when you stop: keratosis pilaris comes back when you stop. This manages it. Nothing cures it.

The strength exceeds the safety guideline: the cosmetic safety panel's guideline for AHAs is 10% or below. AmLactin sells 12% and 15%.

What it runsPrice per Ounce

AmLactin Daily Nourish Lotion 12% costs $2.02 per ounce. That is cheaper than 27 of the other 36 moisturizers priced on Dermapedia, which run from $0.42 to $97 per ounce.

A body lotion for arms and legs, so a bottle goes quickly. How long it lasts matters more than the price per ounce.
