What's actually going on with your skin?

No spam. We hate it too. · Trusted by 5,000+ KP-skin people
Question 1 of 6
Where are the bumps?
The most common spots: upper arms (50% of cases), thighs, and behind. We'll route you to the right strength based on where + how stubborn.
Question 2 of 6
When did you first notice them?
When KP shows up tells us why your barrier is producing too much keratin. Childhood KP is genetic. Adult-onset is hormone- or barrier-related. Both have different routes.
Question 3 of 6
What does the bumpy area look like?
There's no wrong answer here. This just helps us route what to do about the color, not just the texture.
Question 4 of 6
What have you tried?
74% of people we've tested have used drugstore washes that don't have enough acid concentration. Pebble has 4-6% glycolic — therapeutic, not cosmetic. Knowing what you've tried lets us tell you what's actually different.
Question 5 of 6
How sensitive is your skin?
The #1 reason KP serums fail is irritation forcing pause. We need to know your tolerance to pick the right buffering.
Question 6 of 6
What's your goal?
Your timeline shapes which Pebble bundle is yours. 8 weeks is the median time-to-smooth in our clinical (n=312).
