Vitamin E: does it work, and at what %?
Vitamin E is one of the actives we grade on evidence, not marketing. The benefit is real — but only when the dose clears the threshold the research supports. Here's the number, and the products that actually hit it.
The verdict: Tocopherol is an antioxidant that stabilizes vitamin C and supports the barrier.
How we grade Vitamin E
We check the disclosed concentration against the effective threshold from peer-reviewed dermatology literature and regulatory monographs, then weigh the formulation and any product-specific study. The grade is computed from the open rubric — re-run it on any ingredient list and you get the same letter. Also labeled as Tocopherol.

Common questions
What concentration of Vitamin E is effective?
On Visage Theory's rubric, Vitamin E reaches an effective dose at 0.5% and a strong, research-backed dose at 1%. Below that, the labeled benefit is unlikely no matter how good the marketing is.
Is more Vitamin E always better?
Not necessarily — past the effective range you mostly add irritation risk, not benefit. What matters is clearing the threshold in a stable formula, which is exactly what our grade checks.
How do I know a product actually contains an effective dose of Vitamin E?
Most brands list the active but hide the concentration. When the dose isn't disclosed we can't confirm efficacy, so we withhold a grade rather than guess. Products that disclose an effective dose are graded and listed below.
