What are the common causes of closed comedones on the face

Closed comedones are also a relatively common type of acne. This type of acne will form small bumps on the face. Although they are not red or painful, they do not disappear for a long time, which has a great impact on the appearance. There are many reasons for closed comedones, the main one being the blockage of keratin follicles. At this time, some of the cortex in the skin cannot be excreted normally, and protrusions will form on the surface of the skin. If you want to avoid closed comedones, you must exfoliate regularly and keep the facial skin clean to help the normal metabolism of sebum. In addition, dryness, ultraviolet radiation or not paying attention to skin cleansing may cause closed comedones.

6 Reasons Why You Have Closed Comedones

Reason 1: Dryness

When the skin is not moisturized enough, the skin's metabolism will slow down, causing the formation of new skin cells to slow down, making it difficult for old dead skin cells to fall off normally, and as a result, they will accumulate on the skin's surface.

People with the following characteristics should pay special attention: skin easily peels, makeup is not easy to adhere to

Reason 2: Ultraviolet rays

When the skin is exposed to strong ultraviolet rays, in order to protect the body from damage, the skin will become thicker, thus forming a keratin blockage. In addition, ultraviolet rays will accelerate the drying of the skin and become the culprit of keratin hypertrophy.

People with the following characteristics should pay special attention: not paying attention to sun protection in winter, not using sun protection when not outdoors for a long time, and skin dullness and dryness worsen after summer.

Reason 3: Friction

A lot of unintentional physical friction can also cause the accumulation of cuticles to become thicker, such as irritating the skin with your fingers directly without making bubbles when washing your face, and wiping your face vigorously with a towel after washing your face. Such friction will stimulate the skin's self-protection and cause the cuticle to thicken.

People with the following characteristics should pay special attention: Do not use a foaming net, wipe your face vigorously with a towel, or touch your face frequently

Reason 4: Vitamin deficiency

Vitamins are essential for protecting the skin, especially vitamin B and vitamin A, which are closely related to skin metabolism. If these two are insufficient, the growth of new cells will slow down, and without the maturation of new cells, old dead skin cells will remain on the surface of the skin.

People with the following characteristics should pay special attention: those who eat out a lot, have a picky diet, and don’t like vegetables

Reason 5: Male hormones

Androgens can also cause the cuticle to thicken. Although the reason has not been identified, the increase in androgens will indeed disrupt the balance between androgens and estrogens, causing the cuticle to thicken faster. One thing worth noting is that the increase in androgen is also closely related to stress.

People with the following characteristics should pay special attention: those who are easily stressed, have adult acne, and are prone to acne before menstruation

Reason 6: Aging

As we age, our body's metabolism weakens. For example, the repair speed of skin wounds slows down. The body's metabolism weakens, and the natural keratin becomes prone to hypertrophy.
