I frequently cover shopping events like Prime Day, Black Friday and Cyber Monday as a writer for NBC Select, so I know how to find deals that are actually worth buying. I spent weeks combing through thousands of discounts to find the best Prime Day beauty deals — each one I recommend below is highly rated and 20 percent off or more, as well as at its lowest price in at least three months. I’ll frequently update this list throughout Amazon Prime Day.
