Vitamin E occurs naturally in most vegetable oils. The highest concentrations are found in corn, soybeans, sunflower seed, wheat germ, grapeseed, alfalfa, and lettuce. Commercially, it is also added as an antioxidant or preservative in foods and skin care products.
Skin contact with tocopherol is required for it to cause a rash. Discontinuation of exposure to products containing tocopherol should result in improvement and/or resolution of your dermatitis. By law, all products made in the U.S. for topical use have the ingredients
listed either on the product package or the box that contains it, so check the labeling of your skin care products for this ingredient.
If there is not enough information, ask your pharmacist or retailer, or contact the company directly. At work, request a Safety Data Sheet (SDS) to help identify potential sources of exposure.
