• a lot of people forget about color correcting or don’t know how helpful it is:

green concealer: cancels out red blemishes, scars, scratches, rosy cheeks, rosacea etc

orange concealer: cancels out blue undertones such as 5 o'clock shadows, bruises, hickeys, dark circles. (orange primers are also good for freckles and any ashiness in medium to dark skin tones)

purple concealer: neutralizes yellow skin complexions or yellow bruises.

always color correct before applying foundation and never after, it changes the color of your base. youre welcome Source:cubik808
