How AI Skin Analysis Works — and How to Get an Accurate Scan

Step 1: Checking photo quality

The quality of the photo matters more than anything else. Before scoring, AISkinScan checks brightness, sharpness and whether the face is fully visible and facing the camera. Photos that are too dark, blurred, or partly covered by hair, glasses or a hand are rejected rather than scored, because a misleading result is worse than no result.

Step 2: Mapping the face

A face-mesh model places 468 landmark points on the face — around the eyes, nose, lips, jawline and forehead. These points divide the face into regions, such as the forehead, each cheek, the nose, the chin and the under-eye areas. Mapping regions lets the report show not just how much acne you have, but where.

Step 3: Scoring each concern

Separate analysis modules then look for different features in each region. Some use colour (redness for inflamed acne, darker patches for pigmentation, under-eye darkness compared with the nearby cheek), and others use texture (fine-line density for wrinkles, surface roughness for dryness). Machine-learning models trained on dermatologist-graded photos estimate severity. Each concern gets a score from 0 to 100, and these combine into an overall score and grade.

What the results can and cannot tell you

AI analysis is good at measuring visible, surface-level features consistently. It is useful for spotting patterns and tracking whether a routine is helping over weeks and months.

It cannot feel texture, ask about symptoms, look under a dermatoscope, or know your medical history. It cannot diagnose skin cancer, infections, or conditions such as rosacea or eczema. Lighting, camera quality and skin tone can all affect results. Treat any score as a starting point for a conversation with a dermatologist, never as a final answer.

Tips for an accurate, repeatable scan

• Face a window with soft daylight; avoid harsh overhead lights and direct sun.
• Remove makeup, glasses and anything covering your forehead.
• Hold the phone at eye level, about an arm's length away, and look straight ahead.
• Keep a neutral expression — smiling or frowning creates temporary lines.
• For tracking progress, scan at the same time of day, in the same place, every two to four weeks.
