Final answer:
Towel steaming stimulates the vasodilation of blood vessels in the face, resulting in increased blood flow and improved circulation which can aid in skin health and healing processes.
Step-by-step explanation:
Towel steaming of the face helps to stimulate the vasodilation of blood vessels. This process involves the widening of the blood vessels, which allows for increased blood flow and circulation near the surface of the skin. The heat from the steamed towel causes the blood vessels to expand, promoting better oxygen and nutrient delivery to the facial tissue. Moreover, this enhanced circulation can help in various skin healing processes where, for example, fibroblasts mobilize and deposit collagen, and immune cells like macrophages work more efficiently. Therefore, towel steaming can be beneficial for skin health, potentially aiding in the rejuvenation and recovery of the epidermis.
