For under-eye concealer, choose a shade one step lighter than your foundation with a peachy tone if you have dark circles. For spots and blemishes, choose a concealer that exactly matches your foundation. Those two rules cover almost every concealer decision: lighter and peachy to brighten, exact match to cover.
Two Jobs, Two Different Shades
Concealer does two different jobs, and each job needs a different shade. The first job is brightening, mainly under the eyes, where the goal is to make a shadowed area look lighter and more awake. The second job is covering, mainly spots, redness, and blemishes, where the goal is to make something disappear into the surrounding skin.
Mixing these two jobs up is the most common concealer mistake. A brightening shade used on a spot will draw attention to it, because a lighter patch stands out against the rest of the face. A covering shade used under the eyes will do nothing for dark circles, because it matches the skin instead of lifting it. Knowing which job you are doing tells you which shade to reach for.
Most people need both: a brightening concealer for under the eyes and a matching concealer for spots. Buying one shade and expecting it to do both jobs is why so many people feel their concealer never quite works.
Under-Eye Concealer: One Shade Lighter
For under eyes, go one shade lighter than your foundation — not two or three. One shade lighter lifts the area and makes you look awake. Two or more shades lighter creates a pale, ashy patch that looks worse than the dark circles, especially in photos and daylight.
Tone matters as much as lightness. Dark circles usually have a blue or purple tint, and peach or salmon tones cancel blue and purple. So if your dark circles are noticeable, look for an under-eye concealer with a peachy tone rather than a plain light beige. Fair skin suits a light peach, medium skin suits a true peach, and deep skin suits a deeper orange-peach. The deeper your skin, the deeper the peach needs to be, or it will look ashy.
If your under-eye area is not very dark and just needs a little brightening, a plain concealer one shade lighter than your foundation, with no strong peach tone, is enough. Save the peach corrector for days when the circles are really showing.
Concealer for Spots: Match Exactly
For spots, redness, and blemishes, the rule flips: match your foundation exactly, or match your skin if you are not wearing foundation. A concealer that matches disappears into the surrounding skin, which is exactly what covering means. A lighter concealer on a spot creates a pale dot that draws the eye, and a darker one creates a shadow.
For redness, a slightly yellow-toned concealer can help, because yellow cancels red. But keep the depth the same as your skin — the tone shift should be small. A green corrector can also cancel strong redness, but use it sparingly and only on the red area itself, then cover with a matching concealer on top. Green corrector worn alone looks unnatural.
Apply spot concealer with a small brush or a clean fingertip, pressing it onto the spot rather than rubbing. Rubbing spreads the product thin and moves it off the spot you are trying to cover. Let it sit for a minute, then blend only the edges so the center stays covered.
How to Test a Concealer Shade
Test concealer the same way you test foundation, with one adjustment. For under-eye concealer, test under your eye, not on your hand or jawline, because the skin there is thinner and darker than the rest of your face. Apply a small amount, blend it, and check it in daylight. The right shade makes the area look brighter without an obvious pale patch.
For spot concealer, test it on or near the kind of spot you want to cover, or on your jawline if your skin is clear that day. The right shade disappears into the surrounding skin when blended. Check it in daylight and again after an hour, because some concealers oxidize and darken, just like foundations.
Wear-test before you commit when you can. A shade that looks right in the shop mirror can settle into fine lines, crease, or change color after an hour of wear. A proper test at home, over a full day, is the only fair trial.

Common Mistakes to Avoid
The biggest mistake is going too light under the eyes. A bright white triangle under each eye looks harsh in daylight and gray in photos. One shade lighter is the limit, and the peach tone matters more than extra lightness.
The second mistake is using too much product. Thick layers of concealer crease, crack, and draw attention to the very area you want to hide. Start with a small amount, build only where needed, and set under-eye concealer with a light dusting of powder so it stays in place.
The third mistake is skipping the undertone check. A concealer with the wrong undertone — too pink, too yellow, or too gray — will look off even at the right depth. Match the undertone family of your foundation, and adjust only the tone where the job demands it, like peach for dark circles.
Frequently Asked Questions
Should concealer be lighter or darker than foundation?
It depends on the job. Under-eye concealer should be one shade lighter than your foundation to brighten the area. Concealer for spots and blemishes should match your foundation exactly so the spot disappears into the surrounding skin.
What color concealer covers dark circles best?
A peach or salmon tone works best, because peach cancels the blue and purple tints in dark circles. Fair skin suits a light peach, medium skin a true peach, and deep skin a deeper orange-peach. Pair the peach tone with a shade one step lighter than your foundation.
Why does my under-eye concealer look gray?
A gray finish usually means the concealer is too light for your skin or lacks warmth. Try a shade closer to your foundation with a peach tone, and avoid going more than one shade lighter. On deep skin, a translucent setting powder can also add a white cast, so use a powder that matches your skin.
Can I use foundation as concealer?
For spots, yes — foundation in your exact shade covers small blemishes fine. For under eyes, foundation alone rarely brightens enough, because it matches your skin instead of lifting the area. A dedicated under-eye concealer one shade lighter with a peach tone does that job better.
