Use the power of complimentary colors to conceal difficult scars, blemishes, or skin conditions. The green shade conceals ruddiness (a reddened complexion). The lavender hue conceals sallow skin (a yellowing of the skin due to illness, bruising, or injury). The yellow shade conceals dark regions such as under eye circles, especially on medium skin tones. The pink color brightens and conceals dark regions as well, especially on fair skin.
