First of all, the bar of expectation for the effectiveness of cosmetics products has remained low for way too long. Modern customers demand that claims be backed up, they want to measure the results in an objective way, and they will choose only the products that have been proven to help them.
Second, the delivery of personalized solutions should be instantaneous. With more purchases than ever before being made online, we don't have time to wait around. Therefore, an image that can be captured in seconds and a diagnostic that can be delivered within a minute, combined with personalized product recommendations, is the way to go.
