What is the black spot on my face?

Some people always feel that a layer of black stuff grows on their face, but they don’t know what it is. In fact, most people will have dark spots, but the specific details can only be known after a detailed examination. It is mainly a symptom of the disease that will appear after long-term exposure to ultraviolet rays, so you should avoid exposing your skin to the sun.

Dark spots, also known as pigmentation, mostly occur on the face and are common in women. It is a disease that seriously affects people's appearance and makes people upset. Studies have shown that there are many causes of facial skin spots, which can be summarized into the following factors:

If people's facial skin is exposed to the sun for a long time, especially when it is directly exposed to ultraviolet rays without any cover, it is easy to cause pigmentation. After using inferior cosmetics, or long-term use of cosmetics that are inconsistent with their own skin properties, some people's skin will experience allergic reactions or inflammation, and it may also cause pigmentation and form dark spots.

Dark spots can be caused by a variety of reasons, including female endocrine (hormone) imbalance, digestive dysfunction (such as long-term constipation), liver dysfunction, excessive mental stress, severe lack of sleep, anemia, etc.

In addition, premature aging of the skin is also one of the important causes of dark spots. The epidermal cells on the face are usually replaced every 25 to 30 days. If the skin metabolism is active, even pigmentation will disappear naturally in a relatively short period of time as the stratum corneum falls off. As we age, the skin's metabolism declines and the natural repair ability of the skin's stratum corneum decreases. As a result, the deposited pigments are difficult to fade and turn into dark spots.

A large part of congenital pigmented spots are birthmarks, which are mostly large black or blue-black spots on the face or body, called Ota's macular spots or Ito's macular spots. Another part is pigmentation disorder (zygomatic macular spot) that occurs on the face of Asians. Although it is also congenital, it is not present at birth. It will slowly emerge in adulthood around 20 to 40 years old. The color will deepen due to internal factors such as pregnancy or hormonal imbalance or external factors such as sunlight exposure. Other congenital pigmented spots include coffee spots, freckles and various moles.
