I assume the display is being smeared by skin oils and not makeup or some other cosmetic/pharmaceutical product. This happens to me and is important mostly when I show someone else an image on the display. The easy fix is to wipe the display on your shirt when necessary. I assume any stick-on protector you put over your screen will get just as smeared and will need to be replaced just as often as you already clean the display. If you need to protect the display from something that can damage the surface then a stick-on display may be a good answer.
