Vitamin E: does it work, and at what %?

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.

The supply of Vitamin E we can actually verify

127 products in our index contain Vitamin E. 3 disclose a concentration we can confirm reaches an effective dose — that's 2%. The rest list it without a number, so its effect can't be verified at any price.

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.
