Why does my face look dull? What should you look at first?

“Nothing is exactly wrong, but my face looks dull.” I hear this a great deal in the treatment room, but ‘dull’ is not actually one symptom. Several different things overlap to make it look that way, so they need to be taken apart one by one.

The short answer

There are four main reasons a face looks dull — dead skin building up and dryness so the skin does not reflect light evenly, pigment such as melasma and spots, loss of healthy colour, and shadows from hollowing and uneven texture. Sun and smoking were linked with a dark, blotchy skin tone (186 twin pairs), and those who applied sunscreen daily had 24% less skin ageing over 4.5 years. Sleep affects how tired other people think you look, but there is also a randomised study in which one night without sleep did not change the measurements. At Miso Clinic, 4F Bombom Building, 125 Dongdeok-ro, Jung-gu, Daegu (Exit 1, Kyungpook Nat'l Univ. Hospital Station), +82-53-428-2700, we first sort out which one plays the bigger part.

What are the reasons a face looks dull?

Four reasons a face looks dull
ReasonHow it looksWhat to do first
Build-up and drynessNo glow, looks rough, make-up sits on topMoisturising and barrier repair, managing dead skin
PigmentMelasma, spots, a blotchy toneSun protection, a pigment assessment
Loss of colourLooks pale and tiredCheck sleep, smoking and general health
ShadowsHollowing under the eyes and at the front cheeks, uneven textureVolume and skin texture treatments

Most of the time it is not one thing but two or three overlapping. That is why one cream does not solve it.

Does poor sleep really make the face dull?

Two studies say slightly different things. When 40 people looked at photos of 10 people taken after 31 hours without sleep, they rated them as paler, with more fine lines and dark circles. But in a study that randomised 181 people to one night without sleep, there was no difference, whether skin colour was measured by machine or the photos were rated.

Even in that study, though, the less yellow the skin and the more dark circles, the more others judged the person to “look tired”. My reading is this: one night does not show much, but when sleep stays short and the colour and the area around the eyes change, that is what gets read as ‘dull’.

What about sun and smoking?

In a study of 186 pairs of identical twins, a dark, blotchy skin tone was more common in the twin who had more sun and the twin who smoked. These are comparisons between people with the same genes, so the part played by habits shows clearly.

And in a randomised trial that followed 903 people for 4.5 years, those who applied sunscreen daily had 24% less skin ageing. In the end, this is the foundation of managing dullness.

Does anything I apply help?

If build-up and dryness are the cause, moisturising and barrier repair alone bring back quite a lot of glow. For photoageing across the whole face, prescription retinoids (tretinoin) worked in a 48-week trial (99 people). But they can cause redness and peeling at first, so I start at a low concentration.

I could not find a reliable study comparing ‘tone-up creams’ with one another. Please see looking brighter the moment you apply something and the skin actually changing as two different things.

When should I think about treatment?

When some dullness remains after 2 to 3 months of basic care.

What I consider first, by the dullness that remains (clinical judgement)
What remainsConsidered first
Rough texture, no glowSkin boosters (texture and hydration)
Shadows under the eyes and at the front cheeksRestoring volume
Thinning and loss of firmnessCollagen boosters, RF
Melasma and spots as the main causeA pigment assessment first

If your colour has suddenly got worse, or you also have tiredness or dizziness, check your body (anaemia, thyroid and so on) before your skin.

Dull skin: frequently asked questions

My face has suddenly become dull. Why?

Lack of sleep, dryness and UV are common, but if you also have tiredness or dizziness, have your body checked for things like anaemia.

Will sleeping get rid of the dullness?

One night made little measurable difference, but when sleep stays short, changes in colour and dark circles get read as looking tired.

Do skin boosters help with dullness?

I consider them if the texture is rough and there is no glow. If pigment is the cause, they are not the right fit.
