A LOT of products in the drugstore are based on pseudoscience. Products like Mederma (claims to reduce scars) sound scientific and are expensive ($30/tube), but Mederma is just a gel with some "botanical extract" that has been shown scientifically not to work. (They show before & after photos, but scars naturally look better on the same timescale.) Other products like Airborne (to prevent colds on airplanes) are just dietary supplements which likely do not do as they say. This product even says it is "invented by a mom" -- why should that be a selling point for a medical product? The list goes on and on.
