We believe ingredient transparency should be simple, specific, and honest. Every ingredient we use is disclosed clearly, along with why it’s there and what it does. Just as important, we’re open about what we don’t use and why. No vague claims, no hidden blends, no marketing shortcuts. This index is a straightforward reference to help you understand the materials behind our products and the standards we hold ourselves to.
