Mary Kay used to have (may not anymore) a yellow wrinkle concealer in a bottle (liquid) I would put on under my foundation if I had any dark patches. It's fairly "drying" PG, so I only used it around my eyes. It was a very effective concealer. If you know any Mary Kay handlers in your area? You could spread it with you fingers to conceal dark circles; you could feather it right into the wrinkles themselves with a fine artist/makeup brush and totally hide wrinkles. The stuff really worked well!!!! But the chalky pale yellow worked with my very pale ivory to slightly pinkish complexion/coloration. Might not work the same on other complexion colors as well.
