Maintenance

Use 2–3× per week to keep it.

KP is genetic. Pebble manages it.

§ 06 / Incheon, Korea

K-Beauty was never about sheet masks.

Korean dermatology has spent forty years putting acids on people without burning them off. Pebble was formulated in Incheon — same district as Sulwhasoo and Innisfree — by chemists who treat irritation as a design constraint, not an acceptable cost.

  • Made in Incheon — same district as Sulwhasoo.
  • Centella · Allantoin · Panthenol — the soothing trio Korean derms have used since 1986.
  • 13 INCI ingredients. Nothing extra.
Cica (centella asiatica) leaf with water droplets.

§ 07 / Every Skin

KP looks different on every skin.

The bumps are the same. The visible problem isn't.

If your before-and-afters never look like the ones on the bottle, this is why.

§ 08 / The Routine

60 seconds. In the shower.

A hand applying cream to a damp upper arm, post-shower. Rinsing in the shower, post-Pebble. Skin after two weeks of consistent use.
  1. Wet skin, palm-size of Pebble

    Get in the shower. Pebble goes on damp arms or legs.

  2. Massage 60–90 seconds

    ≈ 60 sec

    This is when the acids work.

  3. Rinse · pat dry · moisturize damp

    SPF in the morning. Always.

  4. Build to daily over two weeks

    Start 2–3× a week. Your skin tells you when to go daily.

§ 07 / The Ritual

One pump.
Sixty seconds.

This is what it looks like.

A coin-sized pump, massaged into damp skin for sixty seconds. That's the part most people skip — and the part that makes the eight-week difference.

  • smooth arms era officially started

    i bought this after seeing the trystrawberry comparison and honestly i was skeptical but week 6 my arms are so smooth my boyfriend asked what i changed. ive had KP since middle school. nothing has worked like this.

    Sarah K. Brooklyn, NY Verified buyer · Used 8 weeks
  • first thing thats actually worked

    ive tried amlactin, the ordinary, cerave sa lotion, paulas choice 2% bha. spent probably $400 over the years. pebble serum got my upper arms smoother in 7 weeks than any of those did in months. the quad acid + niacinamide combo is the difference.

  • great but took longer than i hoped

    wasnt sure at first if anything was happening but week 6 i could feel the difference. by week 10 the redness is mostly gone and the bumps are 70 percent smoother. wish it kicked in faster but the results are real. ill keep buying.

    Jen R. Chicago, IL Verified buyer · Used 11 weeks
  • finally something that doesnt cause PIH

    as a brown girl with KP this is huge. every other acid product left dark spots worse than the bumps. the niacinamide and urea in this actually fade the discoloration instead of making it worse. wedding in june and i can wear the dress.

    Priya M. Jersey City, NJ Verified buyer · Used 8 weeks
  • thigh bumps gone redness GONE

    strawberry legs my entire adult life. this is the only thing thats worked on my thighs specifically. arms responded faster than legs but both are noticeably better. use it 5x a week after shower takes 30 seconds.

  • the texture is so light. doesnt feel sticky like the ordinary lactic. absorbs in 2 minutes and i can put on clothes right after. been using 6 weeks and my arms look like a different persons.

    Yasmin H. Dearborn, MI Verified buyer · Used 6 weeks
  • works really well but mild tingle first 2 weeks

    had to start every other day because the salicylic was a bit much for my sensitive skin. by week 3 i could do it daily no problem. results week 5 onwards. i would say definately worth the 52 dollars if you have moderate KP. severe might need longer.

  • the photos online are NOT exaggerated

    i didnt believe the before and afters and bought the duo just to test. week 8 and i look like the after photos. im not even joking. sent a pic to my sister and she thought i edited it. ordering the trio next time to save more.

    had KP on my triceps and shoulders forever. picked this up because my girlfriend ordered it. been using for 9 weeks and ill literally not stop. shoulders are smooth for the first time since i was a teenager. only product im keeping in my routine.

  • buying again immediately

    200ml lasts me about 8 weeks using on both arms and thighs 4 to 5 times a week. duo subscription is the move. shipping was fast and the bottle is genuinely beautiful. would not switch to anything else now that i found this.

    Hannah B. Nashville, TN Verified buyer · Used 14 weeks
  • works on KP and dark spots both

    im fitzpatrick 5 and every brand only tests on white skin. pebble actually shows results on different skin tones in their photos which is why i tried. 8 weeks in the bumps and the PIH from years of picking are BOTH fading. niacinamide is the GOAT.

    Kiana O. Atlanta, GA Verified buyer · Used 8 weeks
  • good product packaging A+

    the bottle is gorgeous the formula is genuinely effective my arms are smoother. one star off because i wish the pump dispensed slightly more per push, i find myself doing 3 pumps per arm. but the formula itself is the best ive used.

    Lauren P. Boston, MA Verified buyer · Used 7 weeks
  • works but took longer than i hoped

    didnt see much for the first 6 weeks and almost gave up. week 10 finally smooth and the redness is mostly gone. so it works just be patient. 3 stars because the brand promises week 4 to 8 results and mine was week 10. but the result is real.

    this is the part most other acid products get wrong. i can use this daily without my skin getting raw or peeling. its actually balanced. ph 3.8 must be the sweet spot. arms smooth by week 5 and havent looked back.

    im back to update. left a 3 star at week 3 because i wasnt seeing changes. week 8 my arms are smoother than ever. updating to 5 stars because i was impatient. KP takes time. trust the process.

    wanted to love it. used for 8 weeks consistently 5x a week. bumps softened slightly but the redness didnt budge for me. might just be my specific KP type. returned via the 60 day promise no questions asked which i appreciate.

    i have had bumps on my forearms since like 8th grade and just accepted it. tried this on a whim. 7 weeks in and the inner forearm where it was worst is basically clear. so weird seeing my own arm and not flinching at the texture.

  • outer thigh KP is GONE

    i have had strawberry legs and KP on the outer thighs for so long i forgot what smooth skin even looked like there. 9 weeks of pebble 5 times a week and the bumps are 90% gone, the redness is way down, and the PIH spots are even lighter. wore a bikini last weekend without thinking about it which is INSANE.

    Marisol R. Atlanta, GA Verified buyer · Used 9 weeks
  • tried the ordinary first, this beats it

    spent 2 years cycling thru ordinary lactic, glycolic, amlactin. nothing held. pebble has held for 8 weeks now. the niacinamide must be why. its more balanced than just one acid.

    Kaitlyn P. Phoenix, AZ Verified buyer · Used 8 weeks
  • shoulder PIH actually fading

    im fitzpatrick 5 and most acids leave me with worse dark spots than the bumps i started with. used pebble 7x a week on my shoulders for 10 weeks. the bumps cleared by week 6 and the PIH from years of picking is genuinly fading. niacinamide carries this formula.

  • works but slow

    its working but slowly. arms are maybe 40 percent better at 8 weeks. ill keep using because the trajectory is positive but i was expecting faster based on the marketing. 3 stars feels honest. would buy again with adjusted expectations.

    been on pebble 8 weeks and the bumps on my right calf are basically gone. been hiding my legs since high school. wore a midi skirt to my friends wedding last weekend and didnt even think about it. honestly emotional posting this.

  • week 4 nothing week 8 yes

    im torn. weeks 1 through 4 i was about to leave a 1 star review honestly. weeks 5 through 8 it started kicking in and now my arms are maybe 50 percent better. so the product works it just takes way longer than the brand claims. 2 stars for the misleading timeline 4 stars for the actual results = compromise at 2.

    did the math after my second bottle. duo subscription saves 15 percent and you get free shipping. its like 44 dollars instead of 52 and it shows up before you run out. im on auto now. arms are smooth bumps are essentially gone. definately recommend the sub.

§ 11 / Questions

The honest answers.

What is keratosis pilaris?

It's a buildup of keratin around hair follicles. Tiny rough bumps, usually on arms or thighs. Genetic. Common in 14M+ women. Not a hygiene problem.

Is Pebble safe for daily use?

Yes. The 4% glycolic and 2% salicylic are buffered with cica, allantoin, and panthenol so the actives work without stripping. Start 2–3 times a week, build to daily over two weeks.

When will I see results?

Texture change in 1–2 weeks. Visible bump reduction at week 3–4. Photographic results between week 8 and 12. KP is genetic, so this is management, not cure.

Can I use it with retinol?

Yes, but not in the same shower. Alternate days. AHAs and retinol both exfoliate — combined, they over-strip.

Is it safe for sensitive skin?

The cica complex was added because Korean derms treat irritation as a design constraint, not a side effect. That said, start every other day and patch-test on a small area first. If you've reacted to AHAs before, talk to your dermatologist.

Can I use it on my face?

It's formulated for body skin. Facial skin is thinner; we'd rather you use a face-specific actives product.

Pregnant or nursing?

Salicylic acid in topical wash-off products is generally considered low-risk, but everything skincare during pregnancy should be cleared with your OB. We default to caution.

What's the 60-day promise?

Try Pebble for 60 days. If your skin is no smoother, email us. We refund. No bottle return required.

Where do you ship?

US and Canada to start. EU rolling out late 2026. Free US shipping over $40.

How do I cancel a subscription?

Two clicks in your account. Or one email. We don't make you call anyone.
