Dull Skin? 7 Common Causes and a Simple Brightening Routine

Dull skin looks flat, tired and slightly grey rather than fresh and luminous. It's rarely a sign of anything serious – it usually means light isn't reflecting evenly off the skin's surface. Fix the cause, and the glow comes back.

7 common causes of dull skin

1. Dead skin build-up – a rough surface scatters light instead of reflecting it
2. Dehydration – thirsty skin looks lacklustre and fine lines show more
3. Sun exposure – tanning and uneven pigment make tone look patchy
4. Pollution – urban particles and smoke add oxidative stress
5. Poor sleep and stress – skin looks paler and puffier
6. Skipping makeup removal – residue clogs pores overnight
7. Using too many harsh products – an irritated barrier looks red and rough, not radiant

A 3-step brightening routine

1. Brighten in the morning

Vitamin C is the go-to ingredient for radiance; niacinamide helps tone look more even. Radiance Booster combines both with Glutathione in one lightweight serum. Follow with moisturiser and SPF 30+.

2. Renew at night

Gentle exfoliation once or twice a week, and a retinoid on other nights, keep the surface smooth so it reflects light. Try Eternal Glow 2–3 nights a week.

3. Hydrate every day

Hyaluronic acid on damp skin plus a moisturiser gives an instant plump, dewy look. See our hyaluronic acid guide.

Quick glow habits

• A cold splash or chilled face roller in the morning to reduce puffiness
• A short facial massage while applying serum
• Fruits, vegetables and enough water through the day
• Changing pillowcases twice a week

How fast will skin brighten?

Hydration and exfoliation show results within days. Vitamin C and retinol need 4–8 weeks for a lasting difference in tone and texture.
