Eyeshadow Placement is a placement technique, not a product — the same shades applied in different zones produce completely different results depending on face shape. On a square face, a square face has a broad, angular forehead and a jaw with a defined, often 90-degree-adjacent corner at the hinge. width stays consistent from temple to jaw rather than tapering, and the chin is flat or minimally curved rather than pointed.
Technique
Technique: Darker shades applied to the outer corner or crease and blended inward or outward to visually widen, elongate, or round the eye shape itself.
The Goal on This Shape
The goal on this shape: Shift the eye's apparent shape and spacing to complement the face's overall proportions For a square face specifically, that means working with the fact that broad and straight across, roughly equal in width to the jaw at the top and the defining feature — strong, straight, with a visible corner at the angle at the bottom — eyeshadow placement is one of the few tools that can adjust that relationship without any permanent change.
Where to Apply It
Where to apply it: Soften the jaw's hard corner and add movement at the temples and chin. Rounded shapes — in a haircut's ends, in frame lenses, in a beard's edge — counter the squareness without erasing the jaw's natural strength, which most square-faced people are better served by softening than hiding. Concentrate the technique on whichever measurement is currently working against that goal, and use a light hand — placement makes the difference here, not product quantity.
