The FORMUSCOPE pledge

No sponsorships. No free-product grades. Every source on the page.

We pay our own way

When we test in hand, we buy the product, and the receipt goes in the evidence file. Brands can’t pay for coverage, placement, or a re-grade.

We show our work

Claims are quoted with capture dates. INCI lists are linked. Studies list design, size, and funding.

We fix mistakes in public

Every correction and grade change is logged with a date and a reason. See the log.
