Six causes of pore blockage

If the pores are clogged, the skin is rough and the smoothness is seriously affected. So, what are the causes of pore blockage? Let's let Xiaobian give you an introduction!

Causes of pore blockage:

One: grease

People with oily skin have this kind of annoying brain, the pores are not only obvious, but also occupied by blackheads, which are mostly related to excessive secretion of sebaceous glands. The sebum secreted by the sebaceous glands is not directly discharged to the surface of the skin, but is excreted from the roots of the hair through the duct of the hair follicle. The function of the pores is like a tube of skin oil. When the skin is excessively secreted, it requires a large volume of tubing. When dredging, the pores will increase. When the skin is over-contaminated and not completely cleaned, the oil and the keratin in the pores fuse together, and an annoying acne is formed! The acne occupies the nest in the pores, and the pores become thicker over time. Therefore, this is why people with oily skin have large pores and love acne.

Two: drying

Drying can also cause large pores, which appear in the relatively dry parts of the cheeks. The openings are obvious and not full, and they are dry, which can be regarded as the initial reflection of skin aging. Because with the increase of age, our sebaceous gland secretion will gradually decrease; secondly, healthy young epidermal cells can do the work in the 28-day cycle of keratin metabolism, and then in the process of late "keratin differentiation" Produces natural moisturizing factors, intercellular lipids and other ingredients. These ingredients work together with sebum to keep the surface of the skin in a moist and soft state. The dry pores indicate that the skin itself has its own functions. It began to slowly decline.

Three: aging

Don't think that the relaxation caused by age is limited to the drooping facial muscles, which also occurs on the pores. Because the surrounding skin is atrophied, the tension is lost, and the pores are gradually elongated in the longitudinal direction, forming a teardrop type or y. The shape of the pores, especially in the vicinity of the cheeks of the cheeks, this phenomenon is particularly obvious, indicating that skin aging has slowly emerged from the deep. Therefore, the pores are dilated and drooping, which is definitely an important symptom of skin aging. In addition to the reduction of superficial sebum, natural moisturizing factors and self-secretion of intercellular lipids, the deeper causes are the loss of collagen and cell loosening and elastic fiber breakage between the dermis and epidermal layers.

Four: sunshine

Ultraviolet rays in the sun are the number one enemy of the skin. It is definitely not an exaggeration. Ultraviolet rays not only cause sunburn to the skin, but also cause sebum oxidation on the surface of the skin. The skin's immunity is reduced, the basement membrane is damaged, and the DNA is damaged. . The most terrifying thing is that the sun is like a pair of scissors. The knife and the knife cut the collagen fiber, causing the skin to lose its elasticity, causing the skin to relax and accelerate the formation of aging pores. Therefore, all seasons, sunscreen is a must.

Five: dirty air

Increasingly dirty and dirty air and environment will cause skin cells to produce a lot of free radicals, which will seriously damage the structure of collagen elastic fibers and make them lose their original elasticity. Their relationship with tightening pores is also mentioned before, but very It is a pity that we have a way to protect the sun, but unfortunately the dirty air is not protected by any skin care products, so the nightly makeup removal and cleaning work is particularly important.

Six: Environment

The foundation of skin health is moisture, and the skin cells are pieces of bricks. Water is needed to connect and bond. Without water, bricks are easy to collapse, forming uneven skin surface and pulling the pore shape irregularly. Modern society allows us to live in an environment where air conditioners are ubiquitous. A large number of people feel dry and dull in the air-conditioned environment. Coupled with the makeup time is too long, often make up the makeup, it is to make the skin less and less water, the pores are also increasingly obvious.
