Why your under-eye concealer keeps creasing
There are few makeup annoyances more predictable than under-eye concealer that looks perfect when you leave the house and somehow finds every fine line on your face an hour later. You blend it carefully. You set it with powder. You may even use a concealer that specifically promises not to crease.
And yet, by midday, there it is: product collecting in little lines underneath the eyes.
The frustrating part is that creasing is not always a sign that your concealer is bad. The skin around the eyes is thin, constantly moving, and naturally has folds. Every time you blink, smile, or squint, the makeup sitting on top of it moves, too.
So the goal is not necessarily to make the concealer completely immovable. It is to stop it from gathering so heavily that the under-eye starts looking drier, heavier, or more textured than it did before you applied anything at all.
And very often, the fix is simply using less.

Do not overdo the prep
Under-eye makeup tends to look better on hydrated skin, but there is a difference between moisturized and slippery.
A rich layer of eye cream immediately before concealer can leave too much product sitting on the surface, which gives your makeup more opportunity to move around. The same goes for layering several skincare products underneath your eyes and applying makeup before they have had time to settle.
You do not have to skip eye cream entirely. Use a light layer, let it absorb, and if the area still feels especially slick, gently blot away any excess before moving on to makeup.

You probably need less concealer than you think
The large triangle of concealer underneath the eye has had its moment. If creasing is your concern, covering the entire area in a thick layer of product usually works against you. Instead, look at where you actually need coverage.
For most people, the deepest darkness tends to sit around the inner corner and along the hollow beneath the eye. Placing a small amount of concealer there and blending outward gives you brightness without leaving an unnecessarily thick layer over every natural line.
If you still need more coverage, build it gradually. A second thin layer is generally easier to control than one generous swipe.
This is also where highly pigmented formulas can help. If a concealer gives you enough coverage with a very small amount, there is simply less product available to settle.

Keep the heaviest coverage away from fine lines
Sometimes we instinctively put the most concealer exactly where we see the most texture, when doing the opposite can look better.
Use the bulk of your product where the discoloration is strongest, then blend whatever remains across areas with more visible fine lines. You still get an even finish, just without packing a thick layer of makeup into every crease.
A small brush is particularly useful here because it lets you place concealer precisely rather than spreading it across the entire under-eye. You can then tap over the edges with your finger or a damp sponge to soften everything and pick up any excess.

Let it crease before you set it
This sounds counterintuitive, but one of the easiest ways to prevent obvious creasing later is to let your concealer settle first. After blending, continue with another part of your makeup for a minute or two. Look up, smile, blink—basically let your face move normally. Then check the under-eye.
If the concealer has already collected in your lines, gently tap it back out with a fingertip, brush, or sponge. Only once the area is smooth again should you add powder. Otherwise, you may be setting the crease in place.

Use much less powder
Powder can help hold concealer in place, but more powder does not automatically mean more staying power.
A thick layer underneath the eyes can absorb moisture and emphasize texture, particularly on dry or mature skin. Baking may work for certain makeup looks and skin types, but it is not always the best strategy when the goal is a natural-looking under-eye.
Try picking up a small amount of finely milled powder with a puff or small fluffy brush, removing the excess, and pressing it only where your concealer tends to move. You may find that you barely need powder on the outer half of the eye at all.

Pay attention to the concealer itself
Technique can solve a lot, but formula still matters.
Very creamy, emollient concealers can look beautifully luminous but may move more throughout the day. On the other end of the spectrum, extremely matte formulas can grip well but make dry under-eyes look more textured.
Somewhere in the middle is often easier to work with: a thin, flexible concealer with enough pigment that you do not need much of it.
And if you already own a concealer you like but find it slightly too rich, changing the way you apply it may be enough. Use less, keep it concentrated where you need it, and remove any excess before setting.

Less is more
Ultimately, a perfectly crease-free concealer is a difficult promise to make because the skin underneath your eyes is supposed to move. A tiny amount of settling by the end of the day is normal. What you are trying to avoid is that thick, obvious line of product that suddenly makes you notice texture you were not thinking about before.
The smoothest-looking under-eye usually comes down to a lighter hand: enough concealer to even things out, enough powder to keep it in place, and no more product than you actually need.
