Clinical Guide to Skin and Wound Care can help you, the practitioner, choose the proper skin and wound care products to facilitate skin health and wound healing based on the classification of the wound and skin condition. To use this tool properly, remember that the composition of a product is often key to its success and may be kept a trade secret. However, for fundamental safety reasons, the U.S. Food and Drug Administration requires a basic level of disclosure about the ingredients in products. Some products may contain ingredients that cause an allergic reaction in certain people or ingredients that shouldn’t be mixed with certain other ingredients. For example, many people are allergic to latex and need to know if it’s a component of a certain product. Labels of most food and household products contain information about their ingredients, which are listed in order of abundance in the mixture. In addition to the label, a Material Safety Data Sheet (MSDS) is available upon request from any manufacturer for any of its products. An MSDS contains health and safety information on the product and its ingredients. Practitioners should be careful when mixing products and should always read the product label and package insert before use.
