It's easy to be tempted into buying products with exotic plant extracts, but a simple, regular cleansing regimen will do your sensitive skin much more good than sporadic blasts of anti-aging toner and the latest expensive goops. Unless a dermatologist advises otherwise, try to limit what you use to cleanse your skin to only two or three products at a time -- a gentle soap, sunscreen, and a moisturizer once or twice a day is plenty for most people. Your sensitive skin comes into contact with a terrible range of chemicals every day, from air pollution to bacteria and plain old dirt. Soaps and body washes are often complicated cocktails, and the more diverse the chemicals you're putting on your skin, the greater the chance that you're introducing an irritant. Also, if you use only a few products and a condition develops, you and your dermatologist will be able to quickly narrow down which ingredient is causing the problem.
