How much lighter or darker should concealer be than foundation?
“One shade lighter” is advice for exactly one part of your face. Everywhere else, it’s the reason concealer goes chalky, grey, or obviously visible in photos.
The short version
- “Concealer should be lighter than foundation” is only true for under-eye brightening. Everywhere else (blemishes, redness, spots), match it exactly.
- Going more than about one shade lighter creates visible greyness or a chalky cast, especially in flash photography.
- Start from your actual foundation match, then adjust from there. Find your foundation shade first if you’re not sure of it.
You’ve heard the advice a hundred times: go one or two shades lighter with your concealer. So you did, and now your under-eyes look brighter, sure, but your blemish concealer leaves a pale halo, and in every flash photo your face reads two different colours.
The advice isn’t wrong. It’s just being applied everywhere, when it was only ever meant for one specific job, the same over-generalising that trips people up on shade versus undertone.
One rule doesn’t fit your whole face
Concealer does two genuinely different jobs, and they call for opposite approaches. Under the eyes, the goal is brightening: a touch lighter counteracts natural shadow. On a blemish, a red patch, or a dark spot, the goal is disappearing, which depends on actually knowing your shade rather than a lighter concealer that just draws a paler spotlight around it.
How much, by area
- Under-eye brightening
Up to about one shade lighter than your foundation match. Beyond that, it stops brightening and starts looking like a separate colour sitting on top of your skin.
- Blemishes and dark spots
Match your foundation exactly, or go very slightly warmer if redness is the main thing you’re covering. Warmth cancels redness better than lightness does.
- Contouring or highlighting
A different job entirely, deliberately lighter or deeper for shape, not for matching skin. Worth keeping mentally separate from “concealer for coverage.”
The things nobody tells you
Flash photography exaggerates every mismatch
A concealer that reads as a subtle, pleasant brightening in a mirror can flash back distinctly pale under a camera flash, the so-called “reverse raccoon” look. If you take a lot of flash photos, err closer to your actual match than the lightest option that still looks fine in person. Anyone who’s seen their own party photos knows the look.
Getting your foundation shade right makes concealer easier, not harder
Every rule above assumes you actually know your real foundation match to begin with. If that’s uncertain, the concealer decision inherits the uncertainty. Get your foundation shade settled first and the concealer choice becomes a small, easy adjustment from a known point.
How do you know you’ve got it right?
Check in daylight and in a flash photo, not just a mirror in soft light. If it brightens under the eyes without reading as a separate patch of colour, and disappears everywhere else rather than drawing attention, it’s working. If either one looks like a distinct pale shape, it’s too light for that job.
Lighter concealer has one job: your under-eyes. Everywhere else, match, don’t brighten.

No, that rule is really just for under-eye brightening. Concealer used to cover blemishes, redness, or dark spots generally works best matched exactly to your foundation, or very slightly warmer to counteract redness, not lighter.
Why does my under-eye concealer look grey or white in photos even though it looks fine in person?
Camera flash exaggerates any mismatch far more than your eyes do in normal light. A concealer that's too light for the brightening effect you want in person can flash back distinctly pale or ashy, sometimes called 'reverse raccoon eyes.'
Can I use the same shade of concealer as my foundation for everything?
For blemishes and redness, yes, that's usually the safest choice. For under-eye brightening specifically, going very slightly lighter is a common and reasonable exception, just not by more than about one shade.
