Frequently asked questions

What is an in-home use test?
An in-home use test, or home usage test, has a panel of consumers who match your target use a product in real conditions over a set period, then collects their perception in a structured way: texture, scent, perceived efficacy, purchase intent. It answers what a lab can't: is the promise perceived, does the routine stick, what do people say about the product, in their own words?
Use test, agency consumer test, clinical test: what's the difference?
A Kayba use test happens at home, in a real routine, over several weeks: it measures declared perception and backs up perception claims. An agency consumer test follows a standardized protocol, in a facility or at home, on a quote. A clinical or tolerance test is run in a lab under medical supervision and is part of the regulatory file. A good program often combines the first and the last.
How many testers do I need for reliable results?
From 20 to 30 testers, perception trends are clear and usable. Standardized panels aim for 60 people or more for public, quantified claims. Our advice: start at 30, then adjust.
Can I target a precise profile?
Yes: age, gender, and your own screening questions (skin type, routine, buying habits) right in the application form. You then pick your testers from the applications.
Are testers paid?
No. They get the product and take part because they're interested in the brand. The free product counts as a material connection, which has to be disclosed when their reviews are published.
Are tester reviews authentic?
Every tester signs an authenticity pledge, every journey is checked before it's validated, and every review comes from someone who received and used the product: the shipment, the surveys and the review are all linked.
What can I say about the results in my marketing?
The results back up perception claims, like “87% find it hydrating”. For a clinical or tolerance claim, you still need a lab test.
How much does a product test cost?
Your Kayba subscription, from €77/mo on Essential billed yearly, plus €12.50 per completed tester journey (€8 on Premium). A journey is complete once every survey is filled in, the final review is in and the authenticity checks are passed. Incomplete journeys aren't billed.
Where do tester reviews show up?
On your Shopify product pages, in the “Testé & approuvé” block: the rating, the measured claims, reviews by profile and before and after photos. The details are on the customer reviews page.
What happens to testers after the test?
The most engaged ones can join your ambassador program on Kayba and keep recommending your products. The test doubles as a recruiting channel.
