Skin Twin AI photo guide

Create an account, confirm your email and complete the four-step onboarding: who you are tracking, skin type and concerns, safety details, and consent.

You can add up to three people. Each person needs to agree before you upload their photo.

• Use natural daylight facing a window; avoid harsh overhead light or flash.
• Face the camera straight on, neutral expression, eyes open.
• No filters, beauty mode, makeup or heavy skincare residue.
• Pull hair back; remove glasses and hats.
• Fill most of the frame with your face. JPG, PNG or WebP under 10 MB.

Check in once a week, at a similar time of day, in the same spot and light. Small changes in lighting can move scores more than real skin changes.

Your skin score summarises 11 cosmetic metrics on a 0–100 scale. 80+ reads as excellent, 65–79 good, 50–64 fair, below 50 a focus area.

Arrows show the change against your previous check-in. One week is noise; look for trends over a month.

Usually the face was too small, blurred or poorly lit. Your quota is returned and the rejected photo is queued for erasure. Retake following the steps above.

To keep analysis available for everyone: up to 3 scans per 10 minutes and 10 per day per account.
