Allergic skin will be red, tight or itchy, these are signs that your skin has signs of allergies, then you should pay special attention to prevent allergies. Washing water temperature First of all, the first thing to do to prevent allergies is to master the temperature of the water used to wash your face. Some people feel that the weather is cold, so they use hot water to wash their face, or to save time, they wash their face together with the bath, in fact, this is not right, hot water is easy to make the pores increase and destroy the sebaceous film of the face, thus causing allergies; nor can you wash your face with cold water, because the skin in a sensitive state, whether hot or cold water, will produce bad stimulation of the skin, so it is best to wash your face with warm water. The water temperature is just a little higher than cold water. In addition, do not be blown by the cold wind, and do not sunbathe. Some people like to take hot towels on the face, in fact, this is also easy to cause the skin’s resistance to decline, so it is best not to apply heat in the spring. Some people think that moisturizing is not as important as the humidity in the air increases in spring, but in fact moisturizing is still very important for the skin, especially for dry skin. It is best to use some purely moisturizing plant-based sprays in early spring to hydrate the face often, so that the skin is healthy and not so easily sensitive. Skin care also need to reduce the burden too many skin care products can also increase the possibility of skin allergies, so if you find that the skin does not seem to be so comfortable, you should start to give the skin a “load”, such as sunscreen and isolation to choose a good, so since the use of sunscreen, isolation cream is not necessary to use. If you are still worried about the burden on the skin is too heavy, then wear a hat, umbrella are both safe and practical good way. There are also people who will go into the misunderstanding of anti-allergy, for example, some people find their skin more red, with a thicker foundation to cover, which will instead stimulate the skin, increase the burden on the skin, and even develop into dermatitis, so if you find that the skin is more red, you have to do subtraction for the skin instead of doing addition.
