What is green concealer for?
Green sits opposite red on the colour wheel, so a green-toned corrector visually neutralises redness — persistent flushing, the surrounds of a blemish, or general unevenness across the cheeks and nose. It is a correcting step, not a concealing one.
How do I use it without looking green?
Sparingly, and underneath. Apply a thin layer only to the red areas, tap to blend the edges, then apply your normal concealer or foundation over the top. The green should be almost invisible before you add anything else. Too much product is the only way this goes wrong.
Cream, liquid or powder?
Cream and liquid formulas layer more easily under foundation and suit most uses. Green primers cover the whole face and are better for widespread redness rather than targeted spots. Powders are the lightest touch and work over the top of a base rather than under it.
What about other correcting colours?
Peach and orange counter blue-toned darkness, which is why they are used under the eyes. Lavender counters sallowness or yellow tones. Yellow can soften purple discolouration. Most people only ever need one, if any.
