What Is a Patch Test Certificate?
A patch test is a dermatological safety assessment in which a product is applied to the skin of human volunteers under controlled clinical conditions and observed for signs of irritation or allergic reaction. The study is conducted by an independent laboratory, after Ethics Committee approval, under the direct supervision of a qualified dermatologist.
A patch test certificate is the formal document issued by the testing laboratory stating the outcome of that study. It tells you three things: who tested the product, how it was tested, and what the result was. For The Derma Co 5% Vitamin C Daily face serum, all three are published in full on this page.
