Efficacy data quantifies the performance of a skincare product on specific skin parameters such as hydration, firmness, or oiliness. Efficacy testing is carried out at a third-party clinical facility under the supervision of a dermatologist and toxicologist. This data is analyzed by a statistician for clinical relevance, i.e., does the product produce a statistically meaningful effect on the skin parameter being evaluated to support the product claim hypothesis.
