The biggest risk associated with vitamin E use is an allergic reaction. Vitamin E can irritate the skin, making skin problems worse. People with a history of allergic reactions should avoid vitamin E, or should do a ρá†ch test on a small area of skin first.
Because vitamin E oil is a supplement and a beauty product, the U.S. Food and Drug Administration (FDA) do not regulate it. This may mean that two vitamin E oils might have radically different concentrations and produce different effects in the same person.
Many vitamin E products contain additional ingredients. It is important to read the label and consult a doctor if uncertain about the product’s safety.
