Recently, there have been many patients with red, itchy and ulcerated skin. Now that the temperature is rising and everything is reviving, people are going out more frequently. As the weather gets warmer, there are more spores, pollen, and dust caught in the air, and spring has really turned into a high season for skin diseases. Many of you will also find that every year spring skin always has this and that problem. While spring is just stepping in, I’ll talk to you about the knowledge of spring-prone skin diseases and how to prevent and treat them so that you can target them. Peach fungus The medical name of this disease is white furfur, is a chronic skin disease of unknown cause. It occurs in children and is most often seen in people with darker skin. The common symptom of “peach fungus” is that the patient will have a patch of whitish or pale red colored spots on the face, 0.5 to 2.0 cm in diameter or larger. After a few weeks, the reddish patches gradually change to whitish patches covered with a few bran-like scales, sometimes with itching, and when exposed to ultraviolet light, a series of inflammatory reactions occur and the skin becomes itchy, red, and flaky. Spring is prone to “peach fungus” because some friends, especially those with dry skin or seborrheic dermatitis, experience a series of inflammatory reactions when their faces are attacked by pollen, air pollutants, and various microorganisms, plus ultraviolet light exposure. This is actually caused by allergies and is a completely different thing from what is medically known as ringworm. Oral vitamin B complex and vitamin C tablets can be taken. Cosmetics and strong alkaline soaps should not be used, and vitamin E cream or aloe vera gel can be used. Try to consume less fat and sweets and no irritating food. This disease should not be treated as ringworm with unauthorized medication, nor should you use dermatitis and other hormone-containing ointments on your own to prevent adverse reactions such as facial pigmentation spots. The most important thing is that you should be aware of the fact that there are many different types of urticaria. The typical manifestation is the appearance of wind clusters of varying sizes all over the body, with severe itching and an increase in the rash after scratching, which occurs more often at night and lasts for several hours before subsiding. The cause of urticaria is complex and cannot be found in about 3/4 of patients. The more common causes include food and food additives, inhalants, infections, drugs, insect bites, sunlight, and genetic factors. In milder cases, antihistamines can be taken, and in more severe cases, antimicrobials can be used. The specific medication to be taken is at the discretion of the doctor at the hospital skin clinic. Skin allergy Skin allergy is something that many people may encounter. It is actually a kind of allergic reaction of the body to allergens, which occurs in people with allergies. There are hundreds of common allergens such as chemical substances (e.g. cosmetics), pollen, dust, ultraviolet light, certain foods (e.g. seafood), etc. Itchiness is the most important characteristic of allergy, and the skin also shows symptoms such as redness, swelling, peeling and atopic dermatitis. With skin allergies, prevention is better than cure. It is important to avoid allergens to the greatest extent possible. For those who are already allergic, you can take oral anti-allergy medications such as paracetamol, cyproheptadine, reserpine, keratan, etc., which act to stop the itching. Never use cosmetics and skin care products again at this time. Wash your face with warm water and apply vitamin E cream or aloe vera gel. Contact dermatitis develops on exposed parts of the limbs that come into contact with exogenous substances. In mild cases, local erythema, itching or burning sensation, slight edema, or dense pinpoint-sized papules; in severe cases, the erythema swells significantly and blisters appear. Properly treated, the disease usually heals within 2 weeks, but there is a risk of recurrence when exposed to suspicious substances again. The disease is caused by direct contact between the skin and certain substances. Common allergens in our life include earrings, rubber, hair dyes, certain cosmetics, etc. Certain plants also tend to cause allergies, such as lacquer tree, nettle, and cat’s eye grass. In case of more severe allergy symptoms, oral anti-allergy medication can be taken. But the best treatment is to avoid contact with the allergen. Usually allergic reactions occur after a period of time, and once they occur, they occur more quickly when re-exposed. If the allergen has been identified with a patch test, it is important to avoid re-exposure in order for the symptoms to not recur. In spring, when skin diseases tend to be high, friends with allergies also need to pay extra attention when playing outdoors. The best means of prevention and treatment is to do a good job of protection and avoid contact with allergens, such as wearing a mask and long clothes. If the allergy is acute and the reaction is severe and intense, go to the hospital as soon as possible.
