How to remove sun spots on arms

Many people often have sun spots on their arms. Sun spots are caused by high-intensity ultraviolet rays and long-term exposure to the skin. It is recommended to use traditional Chinese medicine to regulate the effect. Pay attention to exercise and improve the skin's resistance to the outside world. Try to wear sun-protective clothing when going out, because sun-protective clothing can block part of the ultraviolet rays and prevent secondary sunburn.

Pathological etiology

Sunburn is caused by excessive exposure to ultraviolet B (UVB) rays.

Disease diagnosis

Sunburn, also known as solar dermatitis, should be differentiated from contact dermatitis. The latter is caused by a history of contact with irritants, has nothing to do with sun exposure, can occur in any season, and the skin lesions occur at the site of contact with the irritant.

There is a clear history of working under strong sunlight.

It is more likely to occur in early summer when the skin has not yet tanned and has low tolerance to sunlight, and it is especially likely to occur after sudden exposure of areas that are not often exposed to the sun.

After a certain period of exposure (half to 2 hours), edematous erythema with clear boundaries appears.

The erythema progressively worsens within a few hours, and may even cause blisters and burning pain. Symptoms usually peak within 24 hours.

The course of the disease is 1-2 days for mild cases and 5-7 days for severe cases. After recovery, the skin will peel and there may be mild pigmentation.
