Your Lip Shape Affects More Than You Think

Lip shape influences makeup styles, symmetry perception, even how people interpret your expression.

Scientific Research

Research has shown that there is an "ideal" ratio of upper to lower lip volume that is perceived as most attractive. A balanced fullness is generally preferred, while over-filled lips are often rated as less aesthetic. One study found that lips with an upper lip height that is 20% to 25% of the hemi-lip (half the lip) width were considered most aesthetic

Studies have found that a harmonious upper-to-lower lip ratio is more appealing. The most aesthetically pleasing proportions often fall between a slightly fuller lower lip (approaching the golden ratio of 0.618:1) and an equally balanced 1:1 ratio

Types of Lip Shapes

Lip shape is determined by the relative volume, curvature, and symmetry of the upper and lower lips. Scientific research in facial aesthetics shows that balance between the two lips strongly influences perceived attractiveness.

Full Lips

Full Lips

Full lips create symmetry with a 40:60 ratio and suit bold, blurred, or matte styles without contouring.

Thin Lips

Thin Lips

Thin lips exude refined elegance—use gloss, soft overlining, and a bright center highlight to create fuller, balanced look

Cupid's Bow Lips

Cupid's Bow Lips

Cupid’s bow lips have a defined “M” shape—use liner to trace the peaks and gloss to enhance their soft, feminine charm

Top-heavy Lips

Top-heavy Lips

Top-heavy lips have a fuller upper curve. Use nude liner on top and clear gloss below.

Bottom-heavy Lips

Bottom-heavy Lips

Bottom-heavy lips show more fullness below. Define the top with a rosy liner and keep lower gloss subtle.

Round Lips

Round Lips

Round lips look evenly full. Outline softly with nude liner and add central gloss to enhance shape.

Wide Lips

Wide Lips

Wide lips extend horizontally. Apply darker liner on corners and light gloss at center to create balance.

Asymmetrical Lips

Asymmetrical Lips

Asymmetrical lips add individuality. Use liner to match both sides and add light gloss for uniformity.
