Eczema and dermatitis are problems that have been plaguing people for years. They have complex causes, including intrinsic and extrinsic factors. Dermatitis and eczema flare up because of a multitude of intertwined causes and triggers, and may recur. So, how do we cope?
When an allergic body is exposed to an allergen for the first time, it will produce the corresponding antibodies, which are fixed in the skin and mucous membrane tissue. When the same allergen is encountered again, it will lead to the degranulation of mast cells and basophils, releasing histamine, 5-hydroxytryptamine and other allergic reaction mediators, and allergy can occur. For example, allergy to drugs, food, chemical fiber clothing, plastic, etc. The causes of atopic dermatitis include internal, external factors.
Internal factors
The intrinsic factor is the patient’s own allergic constitution. This plays a leading role in the development of eczema and dermatitis. The instability of the internal environment such as chronic digestive diseases, mental stress, insomnia, excessive fatigue, emotional changes and other mental changes, as well as infectious lesions, metabolic disorders and endocrine dysfunction, can trigger or aggravate the condition of eczema, dermatitis.
1, stress: when people are under pressure, they secrete adrenaline to prepare for dealing with stress. If a person is under long-term stress, the balance of human metabolism will be disrupted, the supply of nutrients needed by the skin will tend to slow down, pigment mother cells will become very active, and spots will grow.
Hormonal imbalance: The female hormone estrogen contained in birth control pills will stimulate the secretion of melanin cells and form uneven spots. The spots formed by birth control pills will stop after the interruption of taking the pills, but they will still stay on the skin for a long time. In pregnancy, due to the increase of female hormone estrogen, the spots will be easy to grow from the 4th – 5th month of pregnancy, and most of the spots that appear at this time will disappear after delivery. However, irregular metabolism, exposure to strong ultraviolet rays, and mental stress will deepen the spots. Sometimes the newly grown spots will not disappear after delivery, so more attention is needed.
3.Slow metabolism: spots will also appear when the metabolic function of liver is not normal or when the ovarian function is reduced. Because the metabolism is not smooth, or the endocrine disorder is in a sensitive state, the pigmentation problem will be aggravated. Constipation can lead to spots, which is actually the result of endocrine disorders that lead to allergies. When the body state is not normal, ultraviolet radiation will also accelerate the formation of long spots.
4, wrong use of cosmetics: the use of cosmetics not suitable for their skin, resulting in skin allergy, in the process of treatment such as excessive exposure to ultraviolet light, the skin will be in order to resist external aggression, in the inflammatory parts of the aggregation of mellanin pigment, so that the problem of pigmentation will occur.
External factors
External factors include diet, inhalants, climate, exposure to allergenic factors, etc. Among them, seafood, spicy food, wine, inhalation of pollen, dust mites, cold weather, exposure to chemicals, soap, detergents, etc. are the most common triggers of eczema and dermatitis.
1, ultraviolet light: exposure to ultraviolet light, the human body in order to protect the skin, will produce a lot of mylanin pigment in the basal layer. So in order to protect the skin will gather more pigments in sensitive areas. Frequent exposure to strong sunlight not only promotes skin aging, but also causes skin disorders such as dark spots, freckles and other pigmentation.
2, bad cleaning habits: because of strong cleaning habits to make the skin become sensitive, this will stimulate the skin itself. When the skin is sensitive, the body in order to protect the skin, melanocytes will secrete a lot of melanin pigment, when the excess pigment on the long spot, blemishes and other skin pigmentation problems.
What are the contraindications for dermatitis patients?
1, avoid scratching: scratching can make the skin constantly suffer from mechanical stimulation and thickening, and even cause infection. The patient’s itchiness is increasing, and the itchiness is increasing, forming a vicious circle, thus prolonging the course of the disease.

3, not hot water scalding: dermatitis, eczema in the acute phase, due to the expansion of capillaries within the skin, there will be varying degrees of skin redness, papules, blisters. The hot water scalding or soaking, redness and swelling aggravated, increased permeability, aggravating the condition. Therefore, dermatitis, eczema patients should be showered with warm water, do not soak in hot water and rubbing hard.
4, avoid stimulating food: chili, wine, strong tea, coffee and other stimulating food, can make itching aggravated easy to make eczema aggravated or recurrence, should be contraindicated.
