Where concealer goes, and why one step lighter is enough
Concealer does two different jobs, and they need two different shades. Most concealer that looks wrong is the right product in the wrong place, or two steps too light.
By The Lucerna shade lab
Concealer is asked to do two jobs that have almost nothing in common. One is to make something disappear: a spot, a patch of redness. The other is to bring light to an area that looks shadowed, usually under the eye. The first job needs a shade that matches your skin exactly. The second needs one slightly lighter. Using one shade for both is why concealer so often looks either obvious or useless.
Covering: match exactly
To hide a spot, the concealer has to vanish into the skin around it. A lighter shade does the opposite: it draws a pale circle around the thing you wanted to hide. Use the exact match for your foundation, dot it directly on the spot, wait thirty seconds for it to thicken slightly, and tap the edges only. Leave the center alone.
Brightening: one step lighter
Under the eye, the goal is different. The area is often darker than the rest of the face, and a concealer one step lighter lifts it back to the level of the cheek. One step. Two steps lighter is the reverse-raccoon effect that looks fine in the bathroom and gray in daylight.
This is why our shade card lists two concealers for every foundation shade. For Lanternlight 210N, the exact match is Halo Blur 4.3 and the brightening shade is 4.2. They are neighbors, and that is deliberate.
Where it actually goes
The common habit is a big triangle under each eye. It uses three times the product you need and gives it three times the chance to crease. Darkness under the eye is usually concentrated in two places: the inner corner, by the nose, and the outer third. Put the concealer there.
Two dots, not a triangle
One at the inner corner, one at the outer third of the under-eye.
Wait thirty seconds
The formula sets a little and covers more.
Tap toward the center
With a fingertip or the pointed end of a damp sponge. The middle of the under-eye gets only what is carried over.
Stop below the lash line
Product right up against the lower lashes is what creases first.
Set with what is left on the puff
Not a fresh load of powder.
About creasing
Skin under the eye moves every time you blink or smile, and any product on moving skin will eventually gather in the lines. The Halo Blur is tested at eight hours under the eye and resists creasing well. No concealer is immune. The three things that help most cost nothing: less product, the thirty-second wait and a very light hand with powder.
If your under-eye is dry, moisturize it first and let it absorb. Concealer on dry skin looks flat by evening however good the formula is.
Other places it earns its keep
- Around the nose, where redness collects: exact match, tapped in.
- Under the brow, to sharpen the arch: exact match, on a small flat brush.
- Around the lip line, to clean up a dark lipstick: exact match.
- Down the center of the nose and on the chin for a little lift: the brightening shade, sparingly.
Choosing the shade
Do not pick a concealer by looking at concealer swatches. Pick your foundation shade first and let the mapping do the rest: the Shade Library lists the exact match and the brightening shade for all forty-eight foundations. If you buy only one, decide which job matters more to you. Spots: the match. Under-eyes: one lighter.
And if it turns out wrong, concealer is covered by the Shade Promise, like the foundation: one free exchange per order within 45 days, even after you have used it.
