I'm going to be a voice of dissent here and say that when shooting "beauty" images, especially for makeup artists' portfolios, it's actually ok to have some specular highlights AND skin smoothing is a no-no as you want to leave texture. Smoothing out texture ends up looking very amateur, but on the other hand, leaving texture in while doing the post production work can be REALLY hard to do and it takes a lot more time. Shortcuts and plugins are fine if you don't actually care about visible blurring or smoothing, but if you do, I suggest watching a lot of tutorials about beauty retouching in addition to input about lighting. Frequency Separation is often touted as a great way to retouch skin and retain texture, but it's actually a really easy way to overdo your images and should only be used sparingly.
In order to show off makeup you want good contrast and punch which IMO a beauty dish is the easiest way to get that look. I use a Mola Setti for most beauty work but there are lots of options. I've also used a large PLM for some things and it still lends that pretty glow but softens the shadows just a bit. You can see some of my work at the link at the bottom of my signature if you're curious about what I mean.
