Makeup tutorials are usually full of different foundations and concealers, but that's not usually necessary.
"I have seen way too many YouTube and Instagram videos where the 'guru' will mix three different full-coverage foundations, add two or three concealers (although the foundation did enough to cover), and then use a few different powders on top," Roe told Insider.
She said sometimes she'll mix a foundation or two to get the perfect shade and consistency for a client, but oftentimes just one product works just fine.
Roe also said that the heavy, full-coverage look that most beauty gurus show off in videos seems great with the right lighting, but her job as a makeup artist is to make sure her clients' skin "still look like skin as much as possible."
