The formation of red blood silk is mostly due to various injury factors. There are no capillaries in the epidermis. The cellular nutrition of epidermis is mainly provided by the third stratum spinosum of our skin epidermis. When acanthocytes are damaged, their ability to provide nutrition will be reduced. Our skin has the ability to repair itself. At this time, the capillaries in the dermis expand independently, helping the spinous cells to provide nutrition, thus forming red blood. The more serious the cell injury in epidermis, the longer the injury time, the heavier the capillary proliferation and migration, and the more serious the red blood. When the skin is damaged by 30%, it is red and spotted; 50% skin injury, linear red blood; 70% of the skin is damaged, which is a red silk net; 90% of the skin is damaged, and it is flaky red blood.
