Demodex Mites Life Cycle: Nutrition and Treatment
Ungex controls the oiliness of the skin to eliminate the main source of nutrition and survival for Demodex mites.
Among the 140 known parasite species, Demodex mite is one of the species that coexists with humans. The parasite lives mostly on the scalp, face, and chest. The two types of Demodex mites, namely "Demodex folliculorum" and "Demodex brevis,” live near or inside of the sebaceous glands and hair follicles. They are mostly active at night but can also be felt moving on the skin during the day.
The Demodex folliculorum mite is a little longer than the Demodex brevis. The length of this parasite is 0.3 to 0.4 mm, while the brevis type is 0.2 to 0.3 mm. Despite these differences, Demodex mites' life cycles are similar in both types.
Demodex mites life cycle
The life cycle of both Demodex sexes is 14 to 16 days. Males and females have anatomical differences. The male is slightly taller and thinner than the female. These mites easily mate at the top of the hair follicles, near the skin. Since the lifespan of adult Demodex is not long, the increase in population on the host skin depends on the number of mating during Demodex mites' life cycle.
After mating, the female mite moves to the sebaceous glands and lays eggs inside them. These eggs are heart-shaped and 0.1 mm long. Demodex "larvae", which has six legs like their parents, hatch in the next 4 days. In the next step, the larvae turns into "protonymph" and slowly enters the sebaceous gland duct. As the protonymph passes through the top hole of the follicle and crawls on the skin, this living thing matures into "deutonymph". Deutonymph moves on the skin and re-enters the follicle duct where it becomes an adult. In general, the larvae grows over 7 days and matures completely to mate again. If the young adult Demodex can mate successfully, the population of these uninvited guests on the host's skin will gradually increase. In this way, Demodex mites life cycle continues over and over. A female mite lays eggs several times during her lifetime if she is lucky, then dies like her couple and her body remains at the place of death.
How is the feeding status during the Demodex mites' life cycle?
Demodex is an organism, and so much like other organisms, they need food. On the other hand, this parasite can only grow on human skin. If they are removed from the skin, they will dry up quickly and die. Much of a Demodex mite’s life cycle is spent eating. But what is Demodex food?
Using an electron microscope, researchers have been able to find the mouth of the Demodex, which has perforating appendages that are sharp and powerful weapons. The Demodex folliculorum has a primary gastrointestinal tract and no anus. Using its mouth, which is in front of the body, Demodex can break down the lipid bilayer and absorb the contents of the cell. Thus, these mites feed on the epithelial cells of the follicles and sebaceous glands.
But in addition to the above, it seems that the most important food during the Demodex mites' life cycle is "sebum" (skin oil). The skin produces sebum to protect itself and prevent it from drying out. Sebum is secreted from the sebaceous glands and spreads throughout the hair and skin. For this reason, both the Demodex folliculorum and Demodex brevis accumulate more in areas with active sebum secretion. These areas include the outer part of the ear, cheeks, forehead, and neck. So, the more food there is, the more parasites there are.
To get rid of them, you must interrupt the Demodex mites' life cycle. One way to do this is to prevent the creature from growing and maturing. The easiest way is to reduce the amount of food available.
With its natural compositions, Ungex controls the oiliness of the skin to eliminate the main source of nutrition and survival for Demodex mites. Because most of these parasites live deep within the skin, Ungex products penetrate the skin and work to wash them out as regular washing is sometimes not enough to full treat Demodex mites.
Also, as mentioned, because these mites are prone to drying out, their lifespan outside the host's body is limited. That's why separating them from the skin interrupts the Demodex mites' life cycle and kills them.
