Sunscreen - Solar tests Experienced centers in in-vitro and in-vivo methods
Science Inspired, Quality Driven.
SPF TESTING
In vitro
SGS IDEA and SGS IEC have been involved in in vitro and in vivo sunscreen testing for many years, relying on a continuous improvement approach to ensure our customers a high level of reliabilityin the results communicated to them. Strict compliance of our study conditions with the current international methods, regular training of our teams, internal audits carried out several times a year, and participation in inter-laboratory proficiency testing schemes organized by BIPEA * , in accordance with ISO/CEI 43-1, are key elements of this approach. *Interprofessional Bureau of Analytical Studies, Paris, France - www.bipea.org BIPEA is a non-profit organization whose mission is to challenge the performance of test laboratories vis-à-vis their results, on an international level. • For each tested product, the obtained value is consistently close to the reference value. The Z-scores recorded by our laboratories always fall within the range of-1 to +1, demonstrating their expertise. This also ensures that the results produced are reliable and meet the expected quality standards.
