There’s a significant difference between concealers, correctors and illuminators, even though most people can’t distinguish them.
You can find numerous concealers on the market that provide coverage for many different imperfections. They come in various forms: sticks, pallets which contain various shades for covering different skin problems, as liquid products in tubes… Sometimes, concealers don’t provide enough coverage, for example for covering extreme under-eye darkness. In that cases you have to use correctors which task is, as its name implies, to correct extreme imperfections. Correctors often come in form of pallets, which contains different shades – green for covering redness; yellow, pink, orange to cover dark circles etc.
Illuminators are used to highlight different areas of face. They can be used alone or after applying corrector. They mostly come in a pen with brush and can be used to highlight the under-eye area, above the lip area, cheek bones etc.

How to cover the under-eye darkness
Correctors are used to cover very dark circles, which concealers can’t fully cover. Pink and peach correctors are used for extreme under-eye darkness. Right shade depends on your skin color. Use pink corrector for pale skin, and for deeper skin tones choose peach shades.
After correction of dark areas, it is necessary to lighten them. For lightening purposes use a yellow concealer or an illuminator. To set that all up, apply the powder foundation on the under-eye area.
