What is closure like?

Closed comedones is a term that many people are unfamiliar with, and many people don’t know what closed comedones are. However, if you mention its nickname, people will suddenly realize that its nickname is acne. Closed comedones grow on many people's faces, but in most cases they are not very obvious. However, if people touch them carefully with their hands, they will feel the presence of closed comedones. So what are closed comedones?

What are closed comedones?

Closed comedones are small grains that grow on the face. They may not be very visible from a distance. They are not red, swollen, painful or itchy. You have to touch them with your hands to feel them. Some people can see that their faces are uneven and rough when the light is facing sideways. The blackheads that people are more likely to find are open comedones, which have larger pores and are easily oxidized by the air. Closed comedones have smaller pores, so the blackheads are trapped inside and are not easy to come out. Although closed comedones are not physically painful, they make the skin look uneven and feel particularly rough. In addition, closed comedones are chronic, they just keep on growing over time, and that’s how it is, which leaves people helpless.

What is the cause of closed comedones?

1. Drying

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.

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.

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.

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.

5. Androgen

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.

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.
