What is it?
Oak Moss Absolute is a fragrance derived from tree lichen that is used in a variety of personal care products.

How do I avoid it?
Skin contact with Oak Moss Absolute is required for it to cause a rash. Discontinuation of exposure to products containing Oak Moss Absolute should result in improvement and/or resolution of your dermatitis. By law, all products made in the US 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 no information ask your pharmacist or call the company directly. At work, request a material safety data sheet (MSDS) to help identify potential sources of exposure.

The avoidance of fragrance agents such as Oak Moss Absolute can be difficult, since so many everyday products contain these substances. One should use only fragrance-free cosmetic and household products. “Unscented” products may contain low levels of a fragrance to cover up an undesirable odor and also should be avoided. Products labeled as “hypoallergenic” do not assure that the product is truly free of fragrance.

Since fragrances are complex mixtures of many ingredients, an individual may tolerate one fragrance but not another. A trial-and-error method of avoiding a fragrance allergen in a product can be performed by applying the product to the forearm in the same small area twice a day for a week. If no dermatitis develops, the product may likely be used safely.
