An oblong (long) face is noticeably longer than wide, with the forehead, cheekbones, and jaw roughly equal in width — the overall outline is closer to a rectangle. Cheek volume is on the lighter side, which makes the cheeks look longer. The overall read is intellectual and grown-up. Common on runways and editorial shoots — but in everyday life, "my face looks too long" is a common concern with this shape.
The makeup goal is the exact opposite of round: add horizontal weight. To shorten the visual length, place shading horizontally at the upper hairline and under the chin. This visually "cuts" the vertical run.
The key contour move is horizontal shadow on the forehead and under the chin. Lay it across the hairline to shorten the forehead, and across the under-chin area to shorten the jaw zone. Cheekbone contour is mostly unnecessary — narrowing what is already narrow makes things worse.
For hair, fringes are the answer. A full or see-through fringe instantly cuts the visual length. Side hair pulled slightly forward to add cheek volume helps too. Length should land between shoulder and collarbone — too long pulls the line back down.
Blush goes horizontally across the apples to anchor a horizontal point. Diagonal or under-cheekbone blush would re-emphasize the vertical line — avoid those. Lips should read horizontal too: keep them full, not thin or small. Glasses-wise, oversized or browline frames disperse the long vertical proportion of the face.
