Discover your lip shape with AI. Get personalized lipstick and makeup technique recommendations for full, thin, heart-shaped, or bow-shaped lips.
Upload a photo and our AI will identify your lip shape - heart, full, thin, cupid's bow, downturned, pillow, and more - with makeup tips made for your exact lip type. Free, no account needed.
Your lip shape determines which makeup techniques actually work for you — and which ones work against you. Thin lips and full lips need completely different liner strategies. A Cupid's bow and a round lip call for opposite application approaches. Most beauty tutorials skip this nuance entirely, which is why so many lip looks fall flat. Knowing your lip shape means you stop buying lipsticks that wash you out or liner techniques that look off. You'll know exactly how to define, balance, or enhance what you already have — without fillers, without guesswork, and without wasting another product.
Our tool uses advanced facial recognition technology to scan the unique contours of your mouth. It analyzes key data points—such as the definition of your Cupid's bow, the ratio of your top lip to your bottom lip, and the sharpness of your outer corners—to identify your precise lip shape in seconds.
Our AI is trained to recognize 12 distinct lip shapes: Full, Thin, Heart, Pillow (Full & Round), Wide Lips, Golden Ratio, Cupid's Bow, Downturned, Top Heavy, Bottom Heavy, Asymmetrical, and Lollipop (Round Pout).

No. Your photo is sent to our servers only for the analysis you requested. It's processed in memory and never saved to any database or long-term storage. We don't use your photos for AI training, and we never share them with third parties. If you choose to use the "Save my results" feature, only the scan result and the photo you explicitly choose to save are stored — and you can delete them from your account at any time.
Your lip shape is defined by the definition of your Cupid's bow, the ratio between your upper and lower lip, the width of your mouth, and the angle of your lip corners. The easiest way to find out is to upload a bare-lips photo to our free AI Lip Shape Detector — it maps all these factors and identifies your lip type in seconds.
There are many recognized lip shapes, but the 12 most common are: Full, Thin, Heart, Pillow (Full & Round), Wide Lips, Golden Ratio, Cupid's Bow, Downturned, Top Heavy, Bottom Heavy, Asymmetrical, and Lollipop (Round Pout). Most people have a primary shape with subtle features of a second — our AI detects these nuances for a more precise result.
Knowing your shape changes how you apply products! For example: Thin Lips benefit from "overlining" slightly with a nude pencil to create volume. Round Lips can be defined with a sharp Cupid's bow using liner for a bolder look. Bottom-Heavy Lips look balanced with a darker shade on the top lip and a lighter one on the bottom.
Yes, it is natural for lip shape to evolve. As we age, collagen production slows down, which can make lips appear thinner or less defined. Hydration levels also play a huge role—dehydrated lips can look smaller and wrinkled, while well-hydrated lips look plumper and smoother.
The "Cupid's Bow" is the dip in the center of your upper lip. Defined: A sharp "V" or "M" shape (common in Heart and Bow shapes). Soft/Flat: A gentle curve or straight line (common in Round or Oval shapes). Our AI looks at this specifically to tell the difference between similar shapes.
For the most precise result: 1) Relax Your Mouth: Do not smile, pout, or pucker. Keep your lips in their natural resting position. 2) Remove Makeup: Lipstick (especially over-lined lips) can trick the AI. Clean lips are best. 3) Good Lighting: Ensure the shadow under your nose doesn't hide your upper lip line.
