What Is Your Lip Shape?

Your lip shape is defined by the volume, the definition of the Cupid's bow, and the corners of your mouth.

Cupid's Bow

The upper lip has a distinct, sharp "V" or "M" shape in the center. This shape is classic, defined, and often associated with a youthful appearance.

Key Feature: Defined Peak

Round

Lacks a sharp Cupid's bow. The top lip is a smooth, continuous curve. This shape gives a soft, pouty, and button-like aesthetic.

Key Feature: Smooth Arch

Full / Plump

Both the top and bottom lips are equally voluminous and pillowy. This is the most sought-after shape in modern beauty standards.

Key Feature: Volume

Thin

Naturally slender lips with less vertical height. They are often wider horizontally and have an elegant, sophisticated look.

Key Feature: Subtlety

Heart Shaped

A prominent Cupid's bow on top paired with a heavier bottom lip, but narrower width overall. Resembles a heart symbol.

Key Feature: Compact Pout

Down-turned

The outer corners dip slightly downwards, creating a gentle curve on top. This shape can give a serious or naturally relaxed expression.

Key Feature: Soft Corners

How to Check Your Lip Shape

Our AI analyzes the curvature of your Cupid's bow and the volume ratio between your top and bottom lips.

Relax Your Pout

Upload a photo with a neutral expression. Do not pucker (duck face) or smile too widely, as this distorts your natural shape.

Contour Mapping

The AI traces the Vermilion Border (the edge of your lips) to detect the sharpness of your Cupid's bow and corner angles.

Why Knowing Your Lip Shape Matters

Lipstick isn't one-size-fits-all. The way you line your lips can completely change your facial proportions. Identifying your natural shape is the first step to mastering your makeup.

Precise Overlining

Knowing where your Vermilion Border fades allows you to overline naturally without looking fake.

Facial Balance

If you have a heavy bottom lip, knowing your shape helps you balance it with the top lip for symmetry.

Aesthetic Decisions

Thinking about fillers? Knowing your baseline anatomy helps you communicate exactly what you want to a professional.

Cupid's Bow

"I always tried to round out my lips with liner, but it looked fake. This tool told me to embrace my sharp Cupid's Bow with a red matte lip, and I've never felt more confident!"

Thin Shape

"The overlining tips were a game changer. I realized I was drawing too far outside the corners. Following the 'center-only' overline advice made them look naturally plump."

Full / Round

"Fast and accurate. It identified my round shape correctly. I stopped using dark liner and switched to the recommended gloss finish, and it looks so much softer."

Lip Shape Analysis FAQs

Do I need to remove my lipstick?
Yes, absolutely. Lipstick, especially if it's overlined or a bright color, hides your natural "Vermilion Border" (the edge of your lips). For the AI to detect your true geometry, please use a photo with bare, clean lips.
Should I smile in the photo?
No. Smiling stretches the lips and thins them out, while "duck face" (puckering) distorts the shape completely. Please keep a neutral, relaxed expression with your mouth closed or slightly parted.
Can I change my lip shape?
Physically, no (without cosmetic procedures). However, visually, you can drastically alter your shape using lipliner. Our tool identifies your base shape so you know exactly where to overline or contour to achieve your desired look.
What is the "Cupid's Bow"?
The Cupid's Bow is the double-curve or "V" shape in the center of your upper lip. Some people have a sharp, defined bow, while others have a smoother, rounder curve. Both are beautiful and require different makeup techniques.
