Our favorite celebrities always look stunning on the red carpet, but that doesn’t mean that we can trust their endorsements when it comes to makeup. Kim Kardashian’s KKW concealer and contour kits have come under fire because fans claim that they simply aren’t inclusive enough, and skew far too light. Kylie Jenner’s lip kits are a hit, but many people feel that the names of her blushes are needlessly risque, especially considering her many young fans. Kat Von D is a tattoo artist turned makeup maven who also has her share of controversy behind the scenes of her cosmetics. Sia is a vegan singer who recently endorsed MAC cosmetics. The only problem with that is that it’s well-known that MAC tests their products on animals and they’re not cruelty-free. It seems like Rihanna’s Fenty beauty collection is so fabulous that nobody can fault it. Although competing brand, Make Up For Ever did try to throw some shade on social media, Rihanna responded with an epic clap back.
