eczema

Eczema is a skin inflammatory reaction with severe itching caused by a variety of internal and external factors. It is divided into three stages: acute, subacute and chronic. The acute phase has an exudative tendency, while the chronic phase has infiltration and hypertrophy. Some patients directly present with chronic eczema. The skin lesions are characterized by polymorphism, symmetry, itching and easy recurrence.

The causes of eczema are complex and are often the result of the interaction of internal and external factors. Internal factors such as chronic digestive system diseases, mental stress, insomnia, excessive fatigue, mood changes, endocrine disorders, infections, metabolic disorders, etc., and external factors such as living environment, climate change, food, etc. can all affect the occurrence of eczema. External stimuli such as sunlight, cold, dryness, heat, hot water washing, various animal furs, plants, cosmetics, soaps, artificial fibers, etc. can all induce it. It is a delayed allergic reaction caused by complex internal and external factors.

Shingles

Herpes zoster is an acute infectious skin disease caused by the varicella-zoster virus. Children who are not immune to the virus develop chickenpox when infected. Some patients become carriers of the virus after being infected but do not develop symptoms. Because the virus is neurotropic, it can remain dormant in the neurons of the dorsal root ganglia of the spinal cord for a long time after infection. When the resistance is low or when you are tired, infected, or have a cold, the virus can grow and multiply again and move along the nerve fibers to the skin, causing severe inflammation of the invaded nerves and skin. The rash is generally unilateral and distributed according to nerve segments, composed of clustered herpes and accompanied by pain; the older the age, the more severe the neuralgia. This disease is more common in adults and is more common in spring and autumn. The incidence rate increases significantly with age.

Skin allergies

Skin allergies are also called "sensitive" skin. From a medical point of view, skin allergy mainly refers to when the skin is exposed to various stimuli such as adverse reactions to cosmetics, chemicals, pollen, certain foods, polluted air, etc., causing abnormal phenomena such as redness, itching, peeling and allergic dermatitis. Sensitive skin can be said to be unstable skin, a skin that is always on high alert. Pay special attention to its care.
