You smoothed the bumps. The red is still there.
15% urea, 10% lactic acid, 3% niacinamide — the doses most KP creams stop short of.
- Less catches under your fingertips. Most people feel it in two to three weeks.
- Short sleeves stop being a decision you make in the mirror.
- 15% urea. Softening starts above 10% — below that, urea is a moisturiser.
- 3% niacinamide, for the redness exfoliating alone leaves behind.
90 days. If your skin isn't smoother, we refund you and you keep the bottle.
A mild tingle for the first few days — that's the 10% lactic acid. It settles. If it burns rather than tingles, stop and email us.
The dose. Urea only breaks down keratin above roughly 10%; most body lotions are 4–5% and several premium KP serums sit at 2%. This is 15%, with 10% lactic acid beside it.
No. Nothing does. KP is genetic, and over 60% of people see it return within three months of stopping. This manages it for as long as you use it.
Texture moves first, usually two to three weeks. The AAD suggests judging any KP treatment at four to six weeks. Colour is slower than texture.
Why this works where the last one stopped.
Most body lotions carry 4–5% urea. Premium KP serums often sit at 2%.
Urea only starts breaking keratin down above about 10%. Under that it is a moisturiser — which is why the smoothing never lasted.
Same ingredients. A different dose.
- 15% urea, not 2%
- 10% lactic acid, not a buffered lactate salt
- 3% niacinamide, aimed at the colour

What to expect with KP-15
Not overnight. Texture moves before colour does, every time.
The texture goes first
Run your hand up your arm and less catches. The bumps flatten before they fade.
Then the colour, slowly
Redness and dark marks are the slowest part, and the least predictable. Nobody can honestly promise you a number.
Photographs are illustrations of what keratosis pilaris looks like on arms and thighs, not customer results.
Three actives. Three numbers.
KP is a plug of keratin inside the follicle. You have to soften it faster than the follicle rebuilds it — a dose problem, not an ingredient problem.
- 15% urea — softens the plug and carries the acid in
- 10% lactic acid — loosens the dead skin around it
- 3% niacinamide — the only one aimed at colour
No proprietary complex, no patent. Just the dose most bottles stop short of.

Two or three pumps on clean skin, twice a day — morning and after your shower. Massage it in. No loofah first, no scrubbing.
Rough, bumpy skin on the backs of the arms, thighs, buttocks or cheeks — especially if a drugstore lotion got you part of the way and the redness stayed.
It is not for broken or actively inflamed skin. Let that heal first.
15% urea, 10% lactic acid and 3% niacinamide in a cream base. The full list is on the carton. No proprietary blend.
We'd keep it to the body. This is a body-strength formula and facial KP is usually treated more gently. Patch-test and ask a dermatologist.
Ask your doctor first — that is not a call we can make for you. For children we'd say twelve and up, patch-tested.
Often, partly. Strawberry legs can be KP, clogged follicles, trapped hairs after shaving, or the marks left behind. This works on the keratin part.
The actives don't behave differently by skin tone. But on deeper skin the lasting complaint is usually the dark marks, and marks are the slowest thing to shift. Use sunscreen on exposed areas.
To keep the result, yes. The follicle carries on making keratin either way. Most people drop to once a day once they're happy.
The actives are the expensive part and there is five to ten times more of them in here. It is also cheaper than the premium KP serums, which run $60–70 with a fraction of the urea.
