Many individuals with allergic-skin conditions have the misperception that natural skin products will be better and cause less itching or rash. However, many natural products contain proteins from plants that can be recognized by your immune system and cause a hypersensitivity reaction. Aloe vera is a commonly added plant product that can cause a contact dermatitis (itchy red rash) with frequent use. Many over-the-counter hydrocortisone creams contain aloe vera. For those with sensitive skin, eczema or hives, aloe vera should be avoided. Also know that skin products that contain food oils or proteins might potentially cause sensitization to food, leading to a food allergy. For instance, many over-the-counter (OTC) creams contain nut oils, and these may not be the best choice for infants with eczema who are at risk of developing food allergies. Two OTC creams that do not contain botanicals or food oils/proteins are Aquaphor and Vanicream. Skin reactions can occur not only with new products, but also from products you may have been using for some time.
