Patch Test

Definition

A method of testing for allergic reactions by applying a small amount of product to a small area of skin before full use. For lip products, a patch test is typically done on the inner forearm. If redness, itching, or irritation develops within 24-48 hours, the product should not be used. While Numbrrrz's simple organic formula rarely causes reactions, we recommend patch testing for anyone with known sensitivities.
