Abstract: Systems and methods are provided for improving skincare product formulations to address predicted skin trends. A biomarker analysis system is used to determine concentrations of various protein biomarkers of a user. A skin diagnosis computing device uses the protein biomarker concentrations to determine one or more skin trends, and determines one or more skincare product ingredients to address the skin trends. A skincare product is compounded that includes the one or more skincare product ingredients.

Abstract: A computing device obtains a first video recorded by a first camera (e.g., a rear-facing camera of a mobile computing device) having a first field of view in an illuminated environment and obtains a second video recorded by a second camera having a second field of view (e.g., a forward-facing camera of a mobile computing device) in the illuminated environment that differs from the first field of view. The second field of view is directed toward a face of a live subject. The computing device extracts lighting environment images from the first video and face images from the second video. The computing device processes the face images and the lighting environment images (e.g., using machine learning models) to obtain a plurality of determinations of skin tone of the face and combines the determinations of skin tone of the face to determine a combined determination of skin tone.
