Also referred to as “Subjective Analysis,” these tests report on subjective perception by consumer volunteers who rate the changes they see in their skin after using a tested product. This is often also called clinical consumer efficacy testing if performed through an independent clinical testing facility.
“These subjective results are critical, because they represent whether the study participant appreciated or noticed a difference in their skin after using a final formulation (the product a consumer will actually purchase and use). These tests are much more expensive and time consuming than relying on data from ingredient suppliers that just look at how one individual ingredient affects the skin.”
