We recommend standing in front of a good, natural light source so your face can be clearly seen and isn’t covered by shadows. Ensure your whole face fits within the frame of the photo, and go make-up free for this selfie so you can see what your skin truly looks like. We also recommend taking your before and after photo in the same position, with the same lighting, and even the same outfit if possible—this will give you the best, most accurate representation of your results.
