Three reasons. The technology was developed with dermatologist input and tested against a data set of more than 3 million real facial images before LYMA adopted it. It reads a wide range of skin tones
and types, so a score means the same thing on your face as it does on anyone else's. And capture conditions are standardised, so the same skin scanned twice returns the same result. Accuracy in skin analysis means repeatability, and that is what the scan is engineered for.
