Quick Answer:
Heart-shaped lips have a sharply peaked cupid’s bow and a fuller center on the lower lip, forming a heart outline. They’re often called rare, but no study has counted them.
By Muhammad Rehan Iqbal, Founder and Developer of OvalFaceShape.com, specializing in face shape analysis, interactive facial assessment tools, and educational styling guides.
Heart-shaped lips combine a sharply peaked cupid’s bow on the upper lip with a lower lip that is fullest at the center and narrows toward the corners. Seen from the front, that outline reads as a heart.
Who this guide is for:
This guide is for anyone identifying their own lip shape before choosing makeup, and for people comparing it with filler terminology. The Lip Shape Analyzer on OvalFaceShape.com can confirm the result from a photo.
What Are Heart-Shaped Lips?
A heart shape needs two features at once. First, the cupid’s bow (the double curve at the top of the upper lip) comes to a pointed V with two clear peaks. Second, the lower lip carries its volume in the middle, so the outline tapers toward the corners.
Either feature alone gives a different shape. A sharp bow on an evenly full lower lip is usually described as bow-shaped. A central lower-lip fullness with a soft bow reads as round or full.
Do not confuse this with a heart-shaped face. This article covers the mouth. The heart face shape guide covers the outline of the head.
Heart-Shaped Lips vs Cupid’s Bow Lips
“Cupid’s bow” names one anatomical feature that every upper lip has to some degree. “Heart-shaped lips” names the whole lip outline. Here is how the common neighbors compare:
| Check | Heart-shaped | Bow-shaped | Full / round |
|---|---|---|---|
| Center of upper lip | Sharp point | Soft, rounded curve | Soft or shallow |
| Peaks above the dip | Clearly higher | Slightly higher | Barely visible |
| Lower lip | Fullest at center, tapers | Even width | Full across |
| Corners | Outline narrows | Stays roughly constant | Stay full |
How to Tell If You Have Heart-Shaped Lips?
- Relax your mouth. A smile stretches the corners and flattens the bow.
- Look at the center of your upper lip. A pointed V suggests heart-shaped. A rounded curve suggests bow-shaped.
- Compare peak height to the dip. A clear difference supports heart-shaped. A shallow difference points to full or round lips.
- Check the lower lip. Fullest in the middle and thinner at the corners fits heart-shaped.
- Take one straight-on photo. A mirror reverses your face. The Lip Shape Analyzer measures the same cues from a single neutral photo.
Are Heart-Shaped Lips Rare?
Heart-shaped lips are widely called rare, but I could not find a published population study that counts lip shapes, so any exact percentage you see online is unsupported.
The claim rests on a reasonable mechanism: The shape needs two features at once, and both tend to soften with age, so the combination is probably less common than either feature alone. That is an inference, not a measurement.

Heart-Shaped Lips on Women and Men
The shape is not limited to one sex. A photomorphometric study of 176 people, rated by 250 judges, found that the ratio of upper vermilion height to mouth-nose distance was significantly higher in attractive female and male perioral regions, with sex-specific differences elsewhere. Penna et al., J Plast Reconstr Aesthet Surg, 2015 nih
In both sexes the upper lip is typically thinner than the lower. Measurements of attractive young women found an upper vermilion height of 6.47 mm against 11.64 mm for the lower, and attractive men showed the same pattern. Aesthetic Plast Surg, 2025 For the heart shape, the practical difference is styling: men usually skip lip color and rely on the natural bow.
Shape vs Size: Thin, Small, Full, Soft and Refined
Heart shape describes outline, not size. Any size can be heart-shaped:
| Term | What it describes | Compatible with heart shape? |
|---|---|---|
| Thin / small | Less visible vermilion | Yes, if the V and central taper are present |
| Full | More vermilion volume | Yes, if the bow is pointed |
| Soft | Gentle, rounded edges | Less likely, since softness blurs the V |
| Refined / defined | Crisp edges, clear peaks | Yes, this is the typical look |
| Natural | No makeup or filler | Possible, since the shape does not require enhancement |
What Do Heart-Shaped Lips Mean?
Anatomically, they mean nothing beyond how the lip is built. Face-reading traditions link the philtrum and upper lip to personality, fertility and attraction, but these are cultural interpretations, not evidence, and I don’t present them as fact.
How to Get Heart-Shaped Lips?
Three routes exist, with very different evidence levels:
- Makeup (most reliable): Trace the V with a liner within one shade of your natural color. Keep gloss to the center of the lower lip. Avoid filling the dip or overlining the corners. Satin and gloss catch light on the peaks better than heavy matte. K-beauty “gradient” looks work the same way: color is deeper at the edges and lighter at the center, which emphasizes the central fullness.
- Exercises: I found no strong clinical evidence that lip exercises change lip shape, so I would not rely on them.
- Filler or surgery: Injectors use “heart” as a target result, meaning volume concentrated centrally. Whether it suits you depends on your anatomy, which only a qualified, regulated practitioner can assess. This page is not medical advice and does not recommend any procedure.
A caution on “more is better”: In a study of faces of young white women, the most attractive ratio of upper to lower lip was 1:2, and the authors advised avoiding the overfilled upper lip look. Popenko et al., JAMA Facial Plast Surg, 2017 That study used morphed images of women aged 18 to 25, so treat it as one data point, not a universal rule. sciencedaily
Key Takeaways
- Heart-shaped lips need both a pointed cupid’s bow and a lower lip fullest at the center.
- They are not the same as “cupid’s bow” alone, and not the same as a heart-shaped face.
- “Rare” is a practitioner claim, not a measured fact.
- Size and shape are separate: thin, small and full lips can all be heart-shaped.
- Makeup is the safest way to emphasize the shape. Exercise evidence is weak. Filler needs a qualified assessment.

FAQ’s
Are heart-shaped lips attractive?
Often yes, but attractiveness is subjective. Research links certain lip proportions to higher ratings, with no single “best” shape.
What is the rarest lip shape?
No study has ranked lip shapes by frequency. Heart-shaped lips are commonly named rarest, but that’s observation, not data.
What does it mean to have heart-shaped lips?
Anatomically, only that you have a pointed cupid’s bow and a lower lip fullest at the center. Personality meanings are cultural interpretation.
Are heart-shaped lips rare?
Probably less common than bow-shaped or full lips, since the shape needs two features. No population study confirms how rare.
Is a cupid’s bow the same as heart-shaped lips?
No. Every upper lip has a cupid’s bow. Heart-shaped lips need a sharply pointed one plus a center-full lower lip.
Are heart-shaped lips the same as a heart-shaped face?
No. One describes the mouth, the other the outline of the head.
Can lip filler or makeup create heart-shaped lips?
Makeup can imitate it by tracing the V. Filler is a medical decision for a qualified practitioner after an in-person assessment.
