Red spots on the skin

The skin is the outermost layer of the human body or the first layer of protection. Due to various external stimuli, the skin may sometimes become red and swollen or even have some bumps. The most common reason for this phenomenon in life is allergy. The most important thing for allergies is to find the allergens. Allergies can be serious or minor. At the same time, the treatment methods for skin redness and particles caused by different allergies are not exactly the same, so it is necessary to understand different allergens.

1. Seasonal skin sensitivity

Some people will experience more serious skin allergy problems when the seasons change: dryness, itching, peeling, erythema, etc. Skin sensitivity is related to dry skin, as well as to the environment, climate, age, food and cosmetics. People who are prone to allergies should pay more attention to the balanced intake of dietary nutrition, eat more fruits and vegetables, and less fish, shrimp, beef, mutton, greasy, sweet and irritating food. If allergic symptoms occur, stop using any cosmetics immediately and observe and care for your skin. During this period, do not wash your face with too hot water to avoid irritating the skin, and pay attention to sun protection.

2. Allergy to cosmetics

Certain ingredients in cosmetics can cause skin allergies, irritate skin cells, and cause skin cells to produce antibodies, leading to allergies. If skin allergies are caused by improper use of cosmetics, you should not use ointments for treating general skin diseases at will. Otherwise, it will cause rough skin, pigmentation, and aggravate the skin disease.

3. Neurodermatitis

Neurodermatitis is a common itchy skin disease in adults. The cause of the disease is generally believed to be related to mental factors, such as emotional excitement, excessive work stress, sadness and anxiety, etc. Severe itching is the characteristic of this disease. The skin becomes thicker after scratching, but the boundaries are clear and there is no scale. It is light red in the early stage, and then there is local pigmentation, which often occurs around the neck, behind the elbows, buttocks and sides of the calves.

4. Peach Blossom Ringworm

It is a skin allergy reaction. Some light pink, round red spots will appear on the face. They will be itchy and a little peeling. Because it often occurs in the spring when flowers are blooming, it is called "peach blossom ringworm". This skin disease begins in spring and subsides in summer and autumn. The main symptoms are whitish or reddish round or oval patches on the face with small scales attached to the surface, and sometimes itching. It is more common on the face, but can also be seen on the upper arms, neck, and shoulders. It is common in people with allergic constitution, and is also related to factors such as excessive exposure to wind and sun, indigestion, vitamin deficiency, dry skin, and the use of inferior cosmetics. Do not use anti-tinea drugs indiscriminately, otherwise it will aggravate the condition.
