I recently stopped in a drugstore and looked at the foundation. I decided to go back to buying like I used to. I bought two bottles of the same brand foundation and type. However one darker shade and one lighter shade. My complexion is olive so I can wear different shades usually I buy a light beige.
However I use a darker shade sometimes for a bronze look. Sometimes ifI feelthat a shade is too dark or too light I mix the two shades together in the bottle.
