    It may seem obvious to say so, but the best fabrics for a healthy skin are usually natural ones. Nonetheless, sensitive skin reactions are more frequently a response to chemical additives than to the actual fabric. There are a few precautions that you can take to protect your skin from toxins in clothing.
