While everyday skin conditions can be complex, the solutions don't have to be. That's why our products are based on a philosophy of Multi-Med Therapy-using the right medicines and active cosmetics, in the right formulations, in the right order. As practicing dermatologists, Dr. Rodan and Dr. Fields know that treating the underlying cause of a problem works and yields long-term benefits. To see real changes in your skin, you must use real medicines. Our product development strategy is to combine OTC (over-the-counter) medicines and active cosmetic ingredients to create safe and effective formulations. We take safety and efficacy very seriously, and we know that it takes the right concentration of an OTC drug or active cosmetic to achieve the desired result without adverse effects.
