TRIPLE-ACID RESURFACING SERUM · 120 ML / 4.06 FL OZ
Your shower gets minutes. This works the other 23 hours.
A leave-on treatment for stubborn bumps and rough texture — upper arms, thighs, the spots that shrugged off every scrub. The strongest actives in the Pebble line, dosed for body skin.
“First thing that’s ever touched the bumps on my arms. The week-4 photo is the reason I’m writing this.”
Maya R. · Verified buyer · Photo review“Two weeks in and the rough patch where my jeans rub my thighs is just… gone. I keep checking it like it’s going to come back.”
Dani K. · Verified buyer
“Did every-other-night like the label says, nightly by week 3. My arms are now smoother than my face, which feels illegal.”
Priya S. · Verified buyer · Photo review“I own every scrub, glove and ‘KP lotion’ on the internet. This is the one that stayed on the shelf.”
Lauren B. · Verified buyer“Doesn’t sting, doesn’t smell like a chemistry set, and it’s dry before my shirt goes on.”
Erin W. · Verified buyerIs 8.5% acids too strong for me?
It’s stronger than most facial acids — on purpose, body skin is thicker. Still: start every other night. Mild warmth in the first minute is normal; stinging that lingers means slow down, not push through.
Can I use it on my face?
No. This is dosed for body skin. Your face gets its own, gentler routine.
Do I need to rinse it off?
No — it’s a leave-on. It works precisely because it stays on between showers.

Bumps rebuild 24/7. Your scrub works ten minutes.
Those bumps are keratin plugs — dead protein cementing itself into the pore. Scrub them off Saturday and they’re back by Wednesday, because the plug never left. It just got a haircut.
A leave-on works differently: it stays on your skin and keeps dissolving the plug while you sleep, commute, sit in meetings. Three actives on the label, one job each — no proprietary blends, no “47 botanical extracts.”
- 01
8.5% AHA/BHA Complex resurfaces
AHAs unglue the dead cells at the surface. The BHA is oil-soluble, so it follows the plug down into the pore instead of stopping at the top — the part scrubs physically can’t reach.
- 02
10% Urea softens + hydrates
At 10%, urea does two jobs at once: it breaks down hard, built-up keratin and pulls water into rough skin. It’s the reason this doesn’t feel like an acid.
- 03
2% Niacinamide calms
Supports the skin barrier while the acids work, and helps fade the red-brown marks that bumps leave behind.
Every other night. Then nightly. That’s it.
- 1
Start every other night.
On clean, dry skin — 2–3 pumps per area. This is stronger than most face acids, dosed for the body. Let your skin adjust; don’t rush it.
- 2
Smooth over the rough zones.
Upper arms, thighs, wherever the bumps live. Don’t rinse — it only works if it stays.
- 3
Dry in about a minute.
Then dress or sleep. No film, no sticky sheets. Seal with the Silk Body Oil if it’s in your routine.
- 4
Go nightly around week 2–3.
When your skin stops noticing it. Daytime: SPF on treated areas that see sun — acids raise sun sensitivity. And no, not on your face.
What you’ve already tried, honestly.
We’ll say it: a $10 scrub does something — it knocks the tops off the bumps. Here’s why they keep coming back anyway.

What actually happens — night by night.
- Tonight
- It dries, you sleep. No tingle-marketing — mild warmth on the first uses is normal and fades.
- Week 2
- Run your palm up your arm: less sandpaper. This is when most people switch to nightly.
- Week 4
- Visibly fewer bumps; sleeves and jeans stop being exfoliation events. The photo-comparison week.
- Week 8
- Maintenance mode — many drop to 3–4 nights a week and hold the result.
No made-up percentages. Just a 30-day refund if your skin disagrees.
THE ROUTINE
Resurface + rebuild.
8.5% acids resurface — they take the plug down. Lipids rebuild — they keep the fresh skin underneath calm and sealed. The Silk Body Oil is the seal step, and it’s the reason the serum is easy to stick with nightly: no tightness, no dry rebound.
