Everyday skincare
Why does my skin look dull, sallow or uneven?

Dull skin usually means the surface is reflecting less light, because it is dry, short of water, or covered in a build-up of rough flakes. Sallow skin is a yellowish or greyish cast, often linked to tiredness or years of sun. Uneven skin tone means patches that look darker or redder than the rest, most often from sun or from marks left by old spots. The changes that help most are gentle, regular exfoliating, steady moisturising and daily sunscreen, given four to six weeks before you judge them.
What makes skin look dull
A few everyday causes, often several at once:
- A rough surface. Dry, built-up flakes scatter light instead of reflecting it. Long hours in air-conditioning and cold, heated winters both make this worse.
- Too little water in the skin. Dehydrated skin looks flat and shows fine lines more. Oily skin can be dehydrated too, especially if you wash it often because of humid weather.
- Sun. Over months and years, sun is the biggest everyday reason tone looks uneven and patchy. In tropical sun, patches can look darker within weeks of skipping sunscreen.
- Short sleep and stress. They show as a greyish, tired look, sometimes with small bumps on the forehead, and no product fully hides that. Our advisers suggest keeping to your usual simple routine in weeks like that, rather than piling on new products.
- Too much of a good thing. Exfoliating too often or piling on actives leaves skin red, rough and irritated-looking, which also reads as dull. This one is easy to miss, because the natural response is to add more.
Exfoliating, gently and not too often
Exfoliating helps loosen the dull, built-up surface so skin looks smoother and brighter. Leave-on acids are kinder than gritty scrubs rubbed hard.
- Lactic or glycolic acid suits dull, dry-looking or uneven skin.
- Salicylic acid suits oily skin with congested-looking pores.
Start with one evening a week, then build to two or three evenings at most. Do not use an acid on the same night as retinol. Signs you are overdoing it: plain moisturiser starts to sting, skin looks shiny but feels tight, or redness lingers. If that happens, stop exfoliating for one to two weeks and let your skin settle before starting again at a lower frequency.
Ingredients that help tone look more even
- Vitamin C, as a morning serum under sunscreen, helps skin look brighter and more even. Keep it closed and out of the light; if it turns dark orange or brown, it is past its best.
- Niacinamide helps the look of uneven tone and dullness, and most skin gets on with it well, morning or night.
Introduce one at a time, so you know which one you are seeing. Be patient with darker patches. They change slowly, over months rather than weeks, and a routine helps them look less noticeable rather than making them disappear.
Hydration and sunscreen do more than they get credit for
When someone asks about dullness, our advisers look at moisture first: getting it right often shows more than reaching for a brightening product. Moisturise morning and night, on skin that is still slightly damp from cleansing or toner. In air-conditioned offices, a hydrating toner or essence under your moisturiser keeps the surface smoother through the day.
Sunscreen is what stops your effort being undone: every morning, including cloudy days, and reapplied when you are outdoors for long. Without it, uneven patches tend to darken again.
The night before an evening out, if your skin feels calm, a hydrating sheet mask for about 10 minutes after your usual routine helps your face look fresher the next day. On the day itself, a moisturiser with a soft sheen adds a quick glow. Both are real but short-lived, so enjoy them for what they are.
How long to give it
Roughly what to expect, though every face is different:
| Change | When you may notice it |
|---|---|
| More moisture, morning and night | Within a few days |
| Gentle exfoliating | Smoother texture in two to four weeks |
| Vitamin C or niacinamide | Brighter look in four to six weeks |
| Uneven patches, with daily sunscreen | Gradual, over two to three months, and often only partly |
Do not switch products every week. Take a photo in the same spot, in daylight, before you start, and compare after a month.
What our advisers see
- Settle first, brighten second. Our advisers add a brightening step only once skin is comfortable. If it is red, stinging or breaking out, they look after that first and bring in vitamin C or another brightening product later.
- Brighten in rounds, with rests. Rather than using a brightening serum non-stop, they often suggest rounds of about two weeks on, then a short rest with the effort going into hydration. After a long run of exfoliating or brightening steps, two to four weeks of plain cleanser, moisturiser and sunscreen lets skin settle before you start again.
- Leftover sunscreen can look sallow. Sunscreen and makeup that are not fully washed off at night tend to leave skin looking yellowish and flat the next morning. On sunscreen days, cleanse twice: once to loosen it, once to wash it away.
This week, try
- Apply sunscreen every single morning, including at home near windows.
- Cleanse twice on the evenings you have worn sunscreen.
- Put moisturiser on slightly damp skin, morning and night.
- If you never exfoliate, try one evening this week. If you exfoliate more than three times a week, cut back.
- Take a daylight photo now, to compare in four weeks.
If a dark patch is spreading quickly, or a single spot or patch changes in size, shape or colour, see a dermatologist rather than adjusting your routine. If your skin and the whites of your eyes look yellow, see a doctor promptly.
