How the B4GLOW face, skin and hair scan works, and how accurate it is
Short answerB4GLOW runs computer vision inside your browser. It maps 478 face points to measure face shape, separates skin and hair in the image, then scores six skin signs, reads hair length, colour and texture, and finds your undertone. Accuracy depends most on light, camera sharpness and angle. It is cosmetic guidance, not a medical diagnosis.

What it measures
- Face shape: seven shapes scored from face proportions and jaw angle, with tilt correction.
- Skin: dark spots, redness, uneven tone, texture, shine and dark circles, each with a severity level.
- Hair: length, colour, texture, hairline and facial hair.
- Colour: skin undertone and a 12-season colour palette.
- Scalp: an optional five-zone check (front, crown, back, left, right).
Getting the most accurate result
- Face a window in daylight; avoid overhead or coloured light.
- Remove glasses and pull hair off your face.
- Use the five-frame precision scan, which combines several shots.
- A USB webcam or rear phone camera is usually sharper than a laptop camera.
- B4GLOW shows a reliability rating so you know how much to trust each result.
