As we age, our skin can lose its luminosity, so the radiant glow of L’Oréal Paris Lumi Magique ($42.99) is ideal for marketing consultant Maria, who has just turned 50. This foundation diffuses light across skin in order to erase imperfections without masking them, giving an illuminating finish and a light-to-medium coverage with SPF18. Maria’s shade is W5 Golden Sand. Maria wears a Shen voile vest, $349.
