Are there red spots on your face that are itchy?

If red spots suddenly appear on a person's face and they are very itchy, it is likely caused by allergic dermatitis. There are many causes of allergic dermatitis. Cosmetics, sunlight, and ultraviolet radiation can all cause allergic dermatitis. If this phenomenon occurs, anti-allergic treatment should be carried out. During the treatment period, the diet must be light, pay more attention to rest, and take oral anti-allergic drugs.

What are the symptoms of allergic dermatitis

Allergic dermatitis is an allergic skin reaction caused by contact with allergic antigens. Anyone who is genetically or physically susceptible to specific antigens may develop immediate or delayed allergic dermatitis when exposed to such antigens. The main symptoms are skin diseases such as redness, itching, wheals, and peeling of the skin when the human body comes into contact with certain allergens.

There are many causes of allergic dermatitis, so different patients show different symptoms, which means that there are many different classifications of allergic dermatitis:

1. Contact dermatitis: When the skin and mucous membranes come into contact with external allergens, erythema, blisters, bullae and even necrosis will appear on the body.

2. Symptoms of hormone-dependent dermatitis: The skin will have obvious erythema, papules, desquamation, irritation and other symptoms.

Symptoms of seborrheic dermatitis: It often occurs in areas with abundant sebum secretion, such as the head, face, chest, etc. It starts with mild erythema, covered with grayish white bran-like scales, accompanied by mild itching, and the rash expands. In severe cases, there is exudation, thick scabs, and a foul odor, and the entire head may be affected.

3. Symptoms of cosmetic dermatitis: In mild cases, there is only local skin itching, a few scattered small red papules, erythema and mild swelling; in severe cases, there is local skin edema, diffuse erythema, water scars of varying sizes, and even exudative erosion.

① Itching, especially at night, reduces the quality of sleep, thus affecting work, study and life;

② Frequent scratching of itchy areas. If scratching for a long time, it may aggravate skin inflammation and cause secondary infection of other diseases;

③If allergic dermatitis occurs on the face and other exposed parts, it will affect the appearance, make the patient feel inferior and depressed, and have an adverse effect on the patient's physical and mental health.

Warm reminder: Studies have found that allergic dermatitis is directly related to genetic and environmental factors, but in fact it is the allergic constitution that is to blame. To fight allergic dermatitis, you should start from the root and actively improve your allergic constitution.
