One of the beautiful (but sometimes frustrating when you can’t control yourself) truths about makeup is that you can make it as easy or as complicated as you want.
Case in point: primer. Most of the time, either because I’m inherently lazy or because I’m almost always running behind, I’ll use a single un-tinted pore-minimizing primer all over my face, except for on my lids, where I’ll use a separate eye primer, but sometimes I’ll feel like going the extra mile, so I’ll use a combination of multiple face primers, and sometimes I’ll even incorporate an additional color-correcting primer.
Make Up For Ever’s Step 1 Skin Equalizers are good for things like this.
When I feel like going that extra mile, before applying my main face primer, I’ll use a separate orange-tinted color-correcting primer first, and I like $36 Make Up For Ever Radiant Primer Peach for this, to neutralize any purple, blue and gray tones on my skin, which for me is usually under my eyes, around my mouth and along my jawline.
