Many people have noticed that their pores on the face are becoming larger and larger as they themselves grow. Some people with oily skin also feel confused why these pores are getting larger. In fact, it is not only excessive oil that can lead to greatening pores. The true reasons are diverse. 

People with oily skin usually have many skin problems, such as greatening pores and blackheads. The sebum secreted by glandula sebacea is not discharged directly to the skin surface, but discharged through the hair-follicle drive pipe. At that time, the pores can be regarded as the pipe to transfer the oil. When the oil is excessive and needs larger pipe, the pores will be greatened. If people do not clean the face cleanly, the oil will mix with the horniness in the pores and generate blackhead. The blackheads will further make the pores greaten.

Drying can also result in greatening pores. As we grow, the sebum secreted by glandula sebacea will decrease. If your skin is still healthy and young, the skin will produce natural moisturizing factors to maintain the skin in a soft and moist state. If your pores are dry, to some extent it means your skin has begun its aging.

Ultraviolet rays in sunlight are a serious foe to our skin. Ultraviolet rays can not only make the skin get sunburnt, but also make the sebum on the skin surface oxidized and lower the immunity of the skin. A more serious point is that the sunlight is just like a knife, which can cut collagen fiber short, make the skin loss bounce and accelerate the generation of aged pores. Therefore, it is necessary to do enough sun-proof preparations.

Dirty air is another reason why the pores are becoming larger. The dirty air can produce lots of free radicals in skin cells which can seriously damage the structure of elastic fibers of collagen to make them lose resilience. Then, it is easy for the dirt to make our pores greaten. It is impossible to prevent the dirt air no matter what kinds of skin care products you use. Therefore, it is important to clean the face quite thoroughly.

The environment you are in is also an important factor to influence the pores. Nowadays, when people are at home or in offices, air conditioners are necessary. While air conditioners can make the air dry and indirectly let the skin lose water. Then the pores will become more and more obvious.

Many reasons in our life can lead to greatening pores. Some reasons we can prevent include the shine of sunlight and supplementation of water, etc. reasons we cannot avoid include the dirty air and so on.
