Evernic acid

Evernic acid is a substance derived from natural lichens. It has been used in cosmetics, lotions, and fragrances. How do I avoid it? Skin contact with evernic acid is required for it to cause a rash. Discontinuation of exposure to products containing evernic acid 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. 

Natural lichens can be found throughout most of the world. Dust or spores from these plants can be challenging to avoid. If your rash is primarily in exposed areas of the skin (outside of clothing), rinsing/bathing in a shower after outdoor activities may be helpful.
