What are the causes of sun spots and what treatments are available

What causes sun spots is a question many friends want to know. Many friends will have the following spots on their bodies after a hot summer. These spots are what we often call sun spots. So what is the cause of sun spots? How are sun spots formed? Let us take a closer look at it below.

What causes sun spots

Sunburn is medically known as solar dermatitis, also known as solar erythema. Exposed skin will develop symptoms such as erythema and edema after being exposed to the sun, followed by bran-like desquamation and skin pigmentation. Sunburn is caused by sunlight or other light exposure. It is an acute damaging reaction of the skin to strong light exposure and is a photosensitive skin disease. Sun spots appear as oval protrusions or smooth, dark brown patches that are prone to appear on the outside of the forearms, backs of hands, fronts of calves and face. They are about the size of a grain of rice to a nickel.

Possible treatments

When the skin is exposed to the sun, the pigment stem cells in the basal layer of the epidermis will secrete more melanin. If this melanin cannot be metabolized normally and smoothly, it will lead to the formation of dark spots. When you are young, you will not necessarily get spots from sun exposure. Even if you get mild spots, they will gradually disappear due to your youth and fast metabolism. However, after the age of 30 or 40, due to the influence of internal pigments, more melanin is secreted. If you continue to be exposed to the sun frequently, the skin metabolism will not be smooth and dark spots will naturally form.

There are still many kinds of treatment methods that can be used at present. The most common one is laser freckle removal. It is mainly operated by means of laser treatment equipment. The instrument emits a specific wavelength. The laser emitted at different wavelengths will be absorbed by the pigment in our skin. Generally, after the pigment is gradually absorbed by our body, the spots will fade accordingly.

The above are the causes of sun spots. I believe you already understand them. Sun spots not only affect the appearance, but also harm our skin, so once you have sun spots, please seek treatment in time.
