We offer In-Use testing services to help cosmetic brands validate product performance, consumer satisfaction, and marketing claims—under real-life usage conditions. Whether you’re preparing to launch a new product or strengthen the claims of an existing one, our in-use testing delivers valuable, real-world insights.

What is in-use testing?

In-use testing involves a panel of volunteers using your cosmetic product over a defined period—typically between 7 to 28 days—in their normal daily routine. Participants provide structured feedback on various aspects such as:

• Skin compatibility

• Texture and sensory feel

• Ease of application

• Scent and overall user experience

• Hydration or soothing effects

• Perceived improvements (e.g. softer or smoother skin)

• Overall satisfaction and willingness to repurchase

These studies can be supervised by dermatologists and may include clinical observations, depending on your product and testing objectives.

Can in-use testing support claims?

Yes, in-use testing is widely used to support consumer-perception-based claims, such as:

• “90% of users noticed softer skin after one week”

• “Leaves skin feeling moisturized and refreshed”

• “Light, non-greasy texture”

• “Pleasant fragrance and easy to apply”

These are powerful for product packaging, advertising, and websites. However, if your claims involve measurable or clinical improvements (e.g. wrinkle reduction, increased elasticity), we recommend complementing the in-use test with instrumental or clinical testing for stronger, quantifiable evidence.

We’re happy to help you determine the right testing method based on your product claims.
