I have a feeling I have quite a lot to learn from Calvin, but there was one trick in particular which was so remarkable, I’ve been using it every day since. I can’t believe I’d never seen it before.
When I apply undereye concealer, I used to apply it in a semi-circle under my eye (logical, since that’s where the darkness is). Calvin applied concealer in what he called an “S” (and what I call an “upside-down checkmark”) shape.
He first touched his fluffy blending brush at approximately the center of the undereye (since he wanted to deposit the most product there, in the area that needed the most covering up). Then he moved his brush to the inside corner of the undereye and down the side of the nose. (He said many people have capillaries and redness to cover there anyway.) Then he swung the brush back up, sweeping under the eye and extending all the way from the outer corner of the eye to the outer corner of the brow. I’ll demonstrate on an older photo of me. (Of course you’ll blend-blend-blend until the concealer is invisible.)
This technique had the really remarkable effect covering AND highlighting, seeming to “flatten out” that area (it optically smoothed the hollows under my eyes). It was just one of those makeup tricks that seemed like magic. Try it — I think you’ll be hooked.
