What is face shape detection?

Face shape detection is a process powered by AI technology that analyzes facial features from a photo or live camera feed.

By examining the shapes of the face, eyes, lips, and brows, an AI face analyzer determines the overall face shape, which can be oval, round, square, heart-shaped, oblong, or rectangle. This analysis helps individuals understand their facial structure, enabling them to make more informed decisions about makeup, hairstyles, glasses, and other beauty products.

How does AI face shape detection work?

AI face shape detectors use advanced algorithms and machine learning techniques to analyze facial features. Here’s a step-by-step breakdown of how it works:

  1. Image capture: The process begins with the user uploading a clear photo or turning on a camera on their preferred device.
  2. Facial feature mapping: The AI technology maps out key facial features and the distance between the eyes. 
  3. Shape analysis: Based on prior training, the AI determines the closest face shape match.
  4. Result presentation: The detected face shape is presented to the user along with personalized recommendations for makeup and contouring.

How to use AI face shape detection in your business

AI face shape detection technology has a wide range of applications that go beyond the mere identification of facial shapes. These applications span various industries and offer significant value to both consumers and businesses. Here are some of the most important ones.

✧ Virtual try-on integration

Virtual try-ons are revolutionizing the way consumers shop for beauty products, eyewear, and even fashion accessories. By integrating AI face shape detection into your virtual try-on, you can offer a highly interactive and personalized shopping experience

Therefore, this technology allows users to virtually try on different products, such as:

  • Makeup: Consumers can see how different shades of, for example, foundation, lipstick, and eyeshadow, will look on their specific face shape, as well as get an invaluable impression on contouring techniques.
  • Eyewear: Users can try on various styles of glasses and sunglasses to find the perfect fit for their face shape, enhancing both comfort and aesthetic appeal.
  • Hairstyles: Individuals can experiment with different haircuts and styles to determine which best suits their face shape, eliminating the risk of a bad haircut.

According to research, virtual try-ons keep users engaged 200% longer than traditional online shopping methods and can lead to a 2.4x increase in purchase likelihood. Additionally, brands that integrate virtual try-ons see a significant boost in conversion rates and customer satisfaction.

Customers are more likely to purchase products when they are confident that those products will suit their unique features.

AI face shape detection also provides valuable data for your business that can be used for market research and customer insights. By analyzing the face shapes and preferences of a large user base, you can:

  • Identify trends: Understand which face shapes are most common among your customers, which products are being used for particular shapes, and tailor your product offerings accordingly.
