FAQs

When should I retest?

For most routines, retest after 6–8 weeks of consistent use. Some aging-related changes may require longer.

Should I use Skinara products before retesting?

No. You can use the Progress Test to assess a Skinara routine or other skincare products you are using.

Do I need to sample the same area?

Yes. Collecting from the same facial area under similar conditions gives you the best results.

Should I change my other products during the testing period?

Ideally, keep the rest of your routine consistent. Multiple simultaneous changes make it harder to understand what influenced the result.

Will the test prove that one product caused the change?

It can show changes associated with the period in which you followed your skincare routine, but it cannot prove that one product caused those changes.
