How is the LYMA Skin Scan different from a filter or a fun selfie tool?

Filters are built to flatter. The Skin Scan is built to do the opposite. A filter adjusts the image you see; the Skin Scan analyses the image to score what is actually there, including the markers you would rather it did not find. It exists to show you how your skin routine is progressing, and the areas you should focus your time.
