Tested
Three supplied reports: a patch test with 221 completers and no adverse events reported, an in-vitro irritation study, and an incomplete 12-week stability report.

The story of a rare bioactive, with centuries of documentation, a modern clinical program, and a conviction that nature's best solutions deserve the world's best verification.
Hirudin & Co. was founded on a powerful conviction: some of nature's most effective compounds have been right in front of us for centuries. They simply needed modern science to validate what traditional medicine already knew.
What was missing was rigorous, independently verified, modern clinical evidence. That is exactly what we set out to create.
We invested in a comprehensive clinical and laboratory testing program at two of the world's most respected cosmetic testing institutions: Eurofins CRL and LifeNet Health LifeSciences.
Here is exactly what we tested, who tested it, and what they found. Every study is available for download.
