Sixty tubes on one shelf, all promising to erase everything you’d rather not see. That is a lousy place to learn. Concealer makes far more sense once you understand it’s a spot treatment, not a second layer of foundation. Get that idea straight and the aisle stops being overwhelming.
This is a from-scratch guide. No assumed knowledge, no jargon you’re expected to already speak. By the end you’ll know what to look for, where to put it, and how to tell in the shop whether a tube is worth your money.
What Concealer Is Actually For
Foundation evens out tone across your whole face. Concealer does the opposite job on a much smaller scale: it takes one specific thing and makes it less noticeable. A dark circle under one eye. A healing spot on your chin. A patch of redness beside your nose.
That’s why a tiny dot is usually enough. A pea-sized amount will cover both under-eyes for most people, and many beginners use five times more than they need on their first attempt. More product doesn’t hide more, it just creases, slides, and announces itself.
The Four Things That Decide Whether a Concealer Works for You
Brand, price and packaging matter much less than these four. Get them right and an £8 tube can outperform a £30 one.
1. Shade depth
Depth is how light or dark the product is. The common advice to buy one shade lighter than your foundation gets misused constantly. A shade or two lighter is fine for brightening under the eyes. Going three shades lighter on a spot creates a pale halo that draws the eye straight to the thing you were hiding.
2. Undertone
Two concealers can look identical in depth and behave completely differently because of undertone. Cool-toned skins lean pink or red, warm skins lean yellow or golden, neutral sits between. Match the undertone of your neck rather than your hand, which is often a different colour entirely.
3. Coverage
Sheer, medium and full describe how much pigment sits in the formula. Sheer formulas are forgiving and almost impossible to overdo. Full-coverage ones hide more but punish bad blending. If you’re new, start at medium and build with a second thin layer rather than reaching for maximum pigment on day one.
4. Finish and formula
Matte formulas grip and last but can look flat on dry skin. Radiant or satin finishes sit more like real skin and are gentler around the eyes. If you have dry patches, a hydrating formula in a tube with a doe-foot applicator is a friendlier first purchase than a dense matte stick.
Liquid, Cream, Stick or Colour Corrector?
Liquid is the default for under-eyes, cream is more forgiving on dry or mature skin, and stick formulas travel well and cover spots fast. Colour correctors are a different category altogether: peach, green and orange tones neutralise colour before concealer goes on top. They’re genuinely useful, but they’re a second step, not a starting point.
There’s a fuller breakdown of how each type behaves in this comparison of liquid, cream, stick and colour corrector formulas, which is worth reading once you know which problem you’re solving.
Where to Put It (and Where to Stop)
Beginners tend to draw a big triangle under the eye and blend downwards. That technique is designed for stage lighting and photographs, not for a Tuesday morning. Try this instead:
- Inner corner of the eye where darkness is deepest, applied as three small dots.
- The spot itself, nothing around it. Cover the blemish, not the neighbourhood.
- Sides of the nose if redness bothers you, using whatever’s left on the applicator.
- Skip the outer corner unless you specifically need it. More product there means more creasing.
Applying It So It Looks Like Skin
Warm the product on the back of your hand first, then tap it on with a fingertip or a small fluffy brush. Tap, don’t sweep. Sweeping drags product across the face and thins it out where you needed it most.
Let it sit for about 30 seconds before blending the edges, then set only the areas that crease with the tiniest dusting of powder. Setting everything is what makes concealer look like a mask. If you want a proper sequence from prep to set, this step-by-step concealer routine walks through the order of operations.
Five Mistakes That Trip Up Almost Every Beginner
Most first-tube regrets come from the same handful of habits. Applying too much product, blending with a dragging motion, using a shade three steps too light, powdering the entire under-eye, and expecting one concealer to handle dark circles, spots and redness equally well. That last one is the biggest myth in the category.
If your current tube is behaving badly, the culprit is often technique rather than the product itself. These common concealer mistakes cover the fixes in detail.
Let Your Skin Type Choose for You
Oily skin does better with a slightly mattifying, long-wear formula that won’t migrate by lunchtime. Dry skin needs something creamier, because matte textures cling to flakes and make them obvious. Combination skin can usually wear either, as long as you powder selectively.
Age changes the equation too. Skin thins over time, so heavy formulas settle into fine lines far more readily than they did at 22. If you’re shopping for yourself or a parent, this guide to concealers for mature skin explains which textures actually cooperate.
And if your main concern is post-acne marks rather than active breakouts, the coverage you need is different again. Pigment left behind by old spots responds well to medium coverage with a peachy undertone, which is the approach covered in these concealers for dark spots that hold up past midday.
How to Test One Before You Buy It
Swatching on your hand tells you almost nothing, because the skin there is a different colour and thickness to your face. Ask for a sample pot, or swatch along your jawline and step outside to check it in daylight. Shop lighting flatters everything.
Then watch it for two hours. Concealer that looks perfect at 10am and has slid into every line by 2pm is not the right one for you, no matter how good the reviews are. Note whether it creased, faded, or turned slightly orange as it settled.
Start with one medium-coverage liquid in a shade that matches your neck, learn to apply it sparingly, and only then decide whether you need a second product for brightening or correcting. Two concealers you understand beat ten you don’t. Once the basics feel automatic, experimenting with finish and coverage gets a lot more fun, and a lot less expensive.
