New Eurofins C&PC protocol quantifies pigmentation contrast as a predictor of skin age
Eurofins C&PC has introduced an advanced protocol that establishes a robust link between pigmentary contrast and estimated skin age, offering cosmetic brands a novel endpoint for efficacy substantiation. The method relies on high-resolution imaging and precise colorimetric analysis to measure the contrast between individual pigment spots and surrounding skin. These values are then correlated using machine learning tools and a database of decades of studies on pigment evolution and skin ageing.
This enables calculation of an “age gain”: the reduction in estimated skin age following treatment. For example, if a pigment spot typical of a 60-year-old resembles that of a 52-year-old post-treatment, the protocol quantifies an 8-year age gain. This metric provides a clinically interpretable, objective indicator – bridging biophysical data with consumer-relevant claims.
The protocol is adaptable to diverse phototype, ensuring accuracy and cultural relevance in global trials. It also delivers a reproducible framework for benchmarking formulations targeting hyperpigmentation, complexion uniformity, and overall skin tone improvement.
By integrating this protocol into clinical studies, Eurofins C&PC empowers brands with a scientifically validated, communication-ready measure of cosmetic efficacy, strengthening innovation pipelines and regulatory compliance.
