The place you first touch a concealer wand often ends up with the most product. If you draw a broad shape automatically and then spend time blending it away, the starting shape may be doing more work than the concealer needs to do.
Look at the area you want to cover in even light. Under the eyes, for example, the variation you notice may sit mainly near one corner rather than across the entire lower lid. Around the nose, one small area may need attention while the surrounding skin already looks the way you want. There is no need for symmetrical application when the two sides of a face are different.
Begin with less than you think you need, using an applicator appropriate to the product and keeping it out of the eye. Place a little product on the area itself, then soften the edge into the surrounding skin. Blending the border and repeatedly sweeping across the center are different actions: the second can move coverage away from where you wanted it.
Stop to look before adding
Once the edge is softened, step back from the mirror. If you immediately add more while looking from a few inches away, it becomes difficult to judge whether the first amount was enough. Give yourself a view of the whole face before deciding.
Texture and color also affect the result. A shade that is much lighter than the surrounding skin may draw attention to an area even while covering its original color. A thick layer can create a visible patch of its own. More product will not reliably solve either mismatch.
Try changing only one part of the application on your next attempt. Keep the same concealer and use a smaller amount, or keep the placement and try a different tool. A sequence of small changes is easier to interpret than buying a new formula, brush and powder at once.
For touch-ups, inspect what actually remains. If only one edge has shifted, adjust that edge instead of coating the whole area again. Concealer can have a limited assignment. It does not have to turn into a second layer of foundation simply because the wand is already in your hand.
