What causes freckles? External factors that cause freckles

Some people accidentally find that they have a lot of freckles on their faces. Freckles are sometimes caused by genetic factors, which are beyond our control, and sometimes because people do not develop good habits, such as not doing a good job of sun protection and often staying up too late. Let me introduce to you what causes freckles.

What causes freckles?

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.

External factors that cause freckles

1. Ultraviolet rays: In the summer, people produce a lot of pigments in order to protect the basal layer of the skin, and may accumulate more pigments in order to protect sensitive parts of the skin. 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.

Now, we should be clear about the reasons why freckles appear on the face. Nowadays, due to the high pressure in life and work, people are in a state of tension for a long time, and their skin condition is not very good. There are also some genetic factors that we cannot avoid. In addition to these two factors, freckles can also appear if people wash their faces too cleanly or do not have good sun protection care.
