Well-tolerated by all skin types, vitamin E is safe when it is incorporated into cosmetic products at concentrations of 0.5% or less. However, excessive dosages of tocopherol (>0.5%) can potentially lead to skin irritation or sensitization reactions. Furthermore, individuals with a history of allergic reactions should avoid vitamin E. However, before using a product containing vitamin E, first perform a skin test on a small area of the body.
