Dilated pores

What is a dilated pore?

Pores allow the skin to “breathe” by creating a channel between the skin’s surface and deeper layers. They are filled with sebum and can become blocked, creating blackheads and spots. Excess oil, makeup, sweat and naturally accumulated skin debris are often the cause of dilated pores. The situation can be exacerbated by hot weather, stress and the fact that some of us naturally have larger pores than others.

Often visible in the T-zone, they tend to be localised on the nose, chin and forehead. They are often more noticeable on people with oily skin, even though people with combination and dry skin can also suffer from them. While spots often improve over time, unfortunately this is not the case for dilated pores, which actually get bigger.

Main causes :

Essential for healthy skin, pores allow sebum and sweat to be naturally excreted. However, if your skin is oily they tend to dilate because of an accumulation of dead skin cells and sebum, which leads to other imperfections.

Pores dilate for a number of reasons:


The sun

UVA and UVB rays exacerbate dilated pores by damaging the collagen and elastin fibres in the dermis. The sun thickens the epidermis and stimulates the sebaceous glands to produce excess sebum.

Smoking and pollution

Adopt a healthy lifestyle by cutting down on smoking. The nicotine in cigarettes and pollution destroy the keratin proteins in the skin and interfere with its hydration.


Foods high in fat and carbohydrates have a direct impact on the beauty of the skin. To limit excess sebum production you are advised to adopt a balanced diet, rich in fruit and vegetables.
