Every woman wants to be a beautiful angel. She usually pays great attention to her external image and hopes that her face will be clean and beautiful. She will be very distressed if there is even the slightest flaw on her face. Sun spots are one of the manifestations of these flaws, which have a bad influence on the beauty of the face and are a psychological burden for many people. So what are sun spots and what are its symptoms?

What are the symptoms of sunburn?

Sunspot is solar dermatitis, also known as sunburn, which is an acute inflammatory reaction of normal skin after exposure to the sun, manifested by erythema, edema, blisters, pigmentation and desquamation. This disease is more common in late spring and early summer, and is prone to occur in children, women, skiers and water workers. The intensity of the reaction is related to light intensity, exposure time, individual skin color, physique, race, etc.

The clinical manifestations are: after several hours to more than ten hours of sun exposure in spring and summer, a clearly defined bright red erythema appears on the exposed area. In severe cases, blisters and erosions may occur. Subsequently, the erythema darkens and desquamates, leaving pigmentation or reduction in pigmentation. Conscious burning or tingling sensation, often affecting sleep. Mild cases will recover within 2 to 3 days, while severe cases will take about a week to recover. Some patients may also experience conjunctival congestion and eyelid edema. If a wide area is exposed to the sun, it may cause systemic symptoms such as fever, chills, headache, fatigue, nausea and general discomfort, or even palpitations, delirium or shock.

There are three main stages in the formation of sunburn

The first is the latent stage, which mainly manifests itself in spots hidden in the bottom layer of the skin and cannot be seen by the naked eye.

Then comes the formation stage, which is characterized by moving up to the stratum corneum of the skin and being deposited on the surface of the skin before it has time to be metabolized.

The last stage is the mature stage, which is characterized by the accumulation of a large amount of melanin on the surface of the skin, forming clearly visible spots.

Excessive sun exposure increases the amount of melanin in the bottom layer of the skin and gradually accumulates on the surface of the skin. Most of them are surface or block-shaped, and their color is yellowish brown or brown, which are called sun spots. However, you will not necessarily get spots from sun exposure. Even if you have mild sun spots, they will gradually disappear due to your youth and fast metabolism. But after the age of 30 or 40, due to internal influences, more melanin is secreted. If you are exposed to the sun frequently, your skin metabolism will not be smooth and dark spots will naturally form.

Excessive sun exposure increases the amount of melanin in the bottom layer of the skin and gradually accumulates on the surface of the skin. Most of them are surface or block-shaped, and are yellowish brown or brown in color. These are what we usually call sun spots. What is medically known as sunburn is 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.

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 internal influences, more melanin is secreted. If you continue to be exposed to the sun frequently, your skin metabolism will not be smooth and dark spots will naturally form.

Through the introduction of the above content, I believe that everyone has a certain understanding of the symptoms of sunburn. It is recommended that everyone pay attention to skin care, avoid prolonged sun exposure, and take sun protection measures. If you have sunburn, you must remove and treat it in time to avoid sunburn affecting your appearance and mood. Finally, I hope all friends can restore their beautiful appearance and regain their confidence.
