Benton Glycolic Acid 7% Exfoliating Toner

What is this product?

This is the Benton acid toner to reach for when you want a stated dose rather than a vague one: 7 percent glycolic acid, printed in the product name, left on the skin with no rinsing and no neutralising step. Approach it as an unverified 7 percent, though, because the number that determines what 7 percent does is missing. Benton publishes no pH, no ingredient list and no irritation test for this product on any of its own surfaces collected here, so how briskly it works and how gentle the vehicle is cannot be checked. Treat the brand's claim that it also hydrates and soothes as intent rather than evidence, since no ingredient list exists to confirm a single hydrating ingredient. Skip it if your skin is reactive or new to acids.

What makes it different?

Most acid toners disclose the opposite half of the picture from this one. They publish an ingredient list and stay quiet about the percentage; Benton publishes the percentage in the product name and nothing else. The consequence is practical rather than academic: with no pH and no vehicle, a stated 7 percent does not tell you how hard the product works, so frequency has to be found by cautious trial rather than read off the label. The second thing to know is that the product page's ingredient block, usage block and any test graphics exist only as images, so nothing behind the number was transcribable in this collection.
