Although I'm pretty low-maintenance when it comes to my skincare routine, I have to admit that I'm sometimes a bit baffled by the overwhelming number of products some regimens involve. As a creature of habit, I'm pretty good about applying various creams and serums in the proper order. However, for those not quite so regimented, you may want to share with them that the sequence does matter. According to the American Academy of Dermatology, most dermatologists say that the order in which skincare products are applied can influence how well they work. "Medications or treatments should be applied directly after washing the face," says board-certified dermatologist Susan C. Taylor, M.D. "This ensures that the medications or treatments are properly absorbed by the skin. Otherwise, people may think a product isn't working because it's applied in the wrong order." She recommends that people first cleanse, apply any medication or treatment, followed by a moisturizer and/or sunscreen, and then makeup, if desired. "It's important for people to know that using several products at the same time may not only negate the benefits of each product but also irritate the skin," says Taylor.
