Having your tinted moisturizer looking streaky after a few minutes of application means that there are parts of your face that are not appropriately hydrated (particularly with those individuals with combination-type skin).  The reason these streaks or patches disappear is that your skin is so dehydrated in places, it tends to immediately soak up the hydrating emollients and humectants, leaving the pigment sitting on top of your skin, looking dry and uneven. The same happens when you're using BB or CC creams and liquid foundations. If you get patches and streaks after applying your tinted moisturizer, try using a plain, untinted one until your skin condition gets better. When the lines and patches disappear the next time you apply anything tinted on your face, that means your skin is getting healthier.
