This small pimple on the baby's hand is called friction eczema, and some people call it sandy dermatitis. As the name implies, it is because the baby appears after playing with soil, sand or water. Sandy dermatitis, medically known as papular dermatitis and lichenoid dermatitis, usually occurs in children aged 3 ~ 10. For more health information, pay attention to WeChat official account: Hydrolyzed Ozone Application Alliance. The reason is that children's skin is delicate. After repeated stimulation and friction with water, sand and soap, their defense function is reduced. In addition, strong sunlight and sweat immersion in summer lead to skin inflammation. Chinese medicine believes that summer is hot and children have damp heat. Some children are naturally intolerant of external stimuli such as water, soap, sand, etc., so the damp heat in the body fights against external evils and penetrates into the skin.
Sandy dermatitis
But sand is so common, how can a baby be easily allergic to sand?
This is easy to understand. A baby of one to three years old has just learned to walk. It is the time for the human body's resistance to adjust and develop. In other words, most things in this world need to adapt slowly, including sand, so children are prone to allergies when they touch it. The incidence of this kind of sandy dermatitis is typical, usually on the back of the hand, chest, forearm, and some will have buttocks (because of wearing open-backed pants). This kind of dermatitis sometimes itches, and sometimes it is not obvious.
As a common skin disease prone to preschool children. The damage of sandy dermatitis to the skin is normal skin color or reddish, and the size of papules varies from needle-like to millet-like, scattered or densely distributed but not fused, but slightly moss-like, without blisters and exudation. The rash is symmetrical, generally occurring on the back of fingers, wrists and forearms, and itches consciously. Before dermatitis, children often crawl on the grass, sand or carpet, dig sand or play with building blocks. Blow bubbles with soapy water or washing powder, so that the skin on the back of the hand and wrist is stimulated by friction or allergic to certain substances. The occurrence of this disease is also related to factors such as sunlight exposure.
Sandy dermatitis is easy to recur because it is related to poor human immunity, and the adjustment of human immune system function generally takes 90 days as a cycle. In this process, the baby's sand dermatitis will recur, sometimes light and sometimes heavy, but don't worry about these. As long as after this period of time, the baby's immune system will adapt to sand and so on, and then it will not be allergic to sand in this life. But it takes a process, usually two or three months. In this process, if the acne grows much or itches, you can apply medicine to relieve itching.
It is often found that many parents like to bathe their children with soapy water and hand sanitizer on the grounds that soapy water is cleaner. Do you know that hand sanitizer will destroy the protective layer on the skin surface, lead to decreased resistance, irritate the skin, and lead to more serious dermatitis? Some people don't understand. They take medicine for months and wash it for months. As a result, children's hands are as rough as adults.
How to prevent or reduce the harm of sandy dermatitis to your baby? As parents, it is necessary to limit the time for babies to play with sand. If you have sandy dermatitis, you can apply some itching cream locally to prevent children from scratching and causing infection; It can also be treated with hydrolyzed ozone oil without hormones and antibiotics, which can effectively solve the problem. Never use drugs containing hormones, which is easy and quick, and is potentially harmful to your baby!
