KP Smoothing Spray · Waitlist
KP isn't a moisture problem.
19.1% triple-acid spray — lactic-dominant, pH 3.6–3.8, built specifically for keratosis pilaris. Launching summer 2026. First batch is 500 bottles.
Waitlist gets the launch email first. One message when the bottles ship. Nothing before.
What we're launching.
The KP Smoothing Spray. A spray formula built around three acids at specific concentrations — 9% lactic, 2.1% glycolic, 8% lactobionic — at pH 3.6–3.8. That's 19.1% total active acid blend, lactic-dominant.
Most KP products use one acid. KP involves multiple layers of keratin buildup and a red follicular flush around the bumps. The KP Smoothing Spray uses three acids, each with a job: lactic to dissolve the keratin plug, glycolic and lactobionic to work on the flush.
Every ingredient is disclosed. Every percentage is explained.
The 19.1%, broken down
- 9.0% Lactic acid · AHA Keratin plug
- 8.0% Lactobionic acid · PHA Follicular flush
- 2.1% Glycolic acid · AHA Follicular flush
Why I made this.
"I still have KP. I use this. KP is chronic — we're not promising a cure."
Aymane Lamsouguer · Founder
I've had KP since I was a teenager. The bumps on my arms. The self-consciousness in summer. I tried the lotions, the creams, the acids built for faces that I put on my arms anyway. None of it did what I needed.
When my mother fought cancer, I started reading ingredient lists differently — not just "does this work?" but "what exactly is in this, and can I explain every ingredient?"
The KP product I needed didn't exist. So I worked with a cosmetic chemist — Merima Selman, dip. formulation chemistry — and built one.
I still have KP. I use this. KP is chronic. We're not promising a cure.
One ingredient, as a preview.
- Ingredient
- Lactobionic acid
- Class
- PHA · polyhydroxy
- Concentration
- 8.0% active
- Source
- Oxidized lactose
Lactobionic acid — 8% active. A PHA (polyhydroxy acid) derived from oxidized lactose. Larger molecule than the two AHAs in the formula, so it works on the outermost skin layer with less irritation risk. Binds moisture while it exfoliates.
Lactobionic acid is part of what works on the red follicular flush — paired with the 2.1% glycolic at pH 3.6–3.8. Most KP products address only the bumps; this formula was built for the bumps and the "dots" that can remain after the texture smooths out.
The full ingredient list publishes the day the bottles ship. Every percentage, every reason.
Be first to know when it's available.
The first batch is 500 bottles. Waitlist members get the launch email before anything else — before social posts, before paid ads, before anyone searching for us finds the site.
If you've spent years on products that didn't work for your arms, being on the waitlist is how you get a bottle from the first 500.
You're on the list
Thanks. We'll send one email when the bottles ship.
Nothing before that. If you don't hear from us until summer, that's working as intended.
