What are the causes of freckles?

Some people accidentally find that they have a lot of freckles on their faces. Some freckles are caused by genetic factors, which we cannot control, while others are caused because people do not develop good habits. In this case, we can prevent the freckles caused.

What are the causes of freckles?

1. Internal factors that cause freckles: 1. Stress: When a person is under increased stress, a lot of adrenaline will be secreted. If the stress is high for a long time, the metabolic balance level will be damaged, and the pigment stem cells will become very active.

2. Genetic genes: Freckles have certain genetic factors. They may be inherited from parents or from several generations, and increase with age. This disease is mainly due to an autosomal dominant genetic disease and is also clearly related to sun exposure. In the hot summer the spots will become more and more numerous and darker in color, while in the winter the spots will become lighter but will never disappear completely.

2. External factors that form freckles: 1. Ultraviolet rays: In the summer, in order to protect the basal layer of the skin, people will have a lot of pigments, and in order to protect sensitive parts of the skin, more pigments may accumulate. Frequent exposure to the sun can not only promote skin aging, but also may cause freckles.

2. Bad cleaning habits: Some people may over-exfoliate when washing their faces. Excessive cleaning can make the skin very sensitive. When the skin is sensitive, melanocytes will also secrete melanin, which can cause freckles, blemishes and other pigmentation problems.

Through the above introduction, we can find that there are many causes of freckles, and freckles have a certain impact on the patient's life. Nowadays, people are under relatively high pressure in life and work, and some people are in a state of tension for a long time. Although some skin problems are caused by genetic factors, we cannot avoid them.
