How the dimorphism test works
Sexual dimorphism is one of the four things our AI scores (alongside bone structure, harmony and feature quality). It reads the sex-typed traits of your face and maps them onto a low-to-high dimorphism scale.
- Upload a clear, front-facing photo (good lighting, neutral expression)
- The AI measures jaw width, brow ridge, chin, cheekbones and facial width
- Get your dimorphism score — from soft/androgynous to highly masculine
- See exactly which features to work on to raise it
The facial dimorphism scale
For men, higher dimorphism usually reads as more attractive — but harmony still matters. Learn how it feeds your overall PSL score.

Frequently Asked Questions
What is facial dimorphism?
Facial dimorphism is how strongly a face shows masculine or feminine traits. High dimorphism (in men) means pronounced masculine features — a wide, defined jaw, a strong brow ridge, prominent cheekbones and a broad face. Low dimorphism means softer, more feminine/neutral features. It's one of the core things looksmaxxing raters and the PSL scale weigh.
What is high vs low dimorphism?
High dimorphism = strongly sex-typed features (very masculine for men, very feminine for women). Low dimorphism = softer, more androgynous features. For men, higher facial dimorphism usually reads as more attractive and dominant; for women, lower dimorphism (more feminine) usually does.
Is high dimorphism good?
For men, moderate-to-high facial dimorphism generally scores well because it signals a strong, masculine bone structure — think defined jaw, forward chin and hunter eyes. But balance matters: harmony and proportion count too, so an extremely dimorphic face isn't automatically a high PSL score.
How can I increase facial dimorphism?
Non-surgical levers that sharpen masculine features include getting to a lean body-fat percentage (reveals the jaw and cheekbones), mewing and correct tongue posture, chewing/jaw training, reducing facial bloat (sleep, sodium, hydration), and grooming — a defined hairline, groomed brows and light stubble all raise perceived dimorphism.
