In spring, skin allergy, pollen allergic rhinitis and asthma do not occur directly in contact with the above plants and flowers. Pollen is mainly spread by wind, in which it can be transported to places hundreds of kilometers to more than 2000 kilometers away. For people with allergic diseases or allergies, under the stimulation of allergens, serum IgE will increase to varying degrees every March. People with sensitive skin will have allergic symptoms such as itchy skin, dry and peeling facial skin, and excessive secretion of oil glands, leading to acne and redness. The skin is the second largest immune organ of human body, and it is easy to induce acute urticaria's disease or vascular edema of the skin under the stimulation of allergens, and then respiratory allergic symptoms appear. Pollen allergy in spring can induce allergic rhinitis and asthma syndrome such as itchy nose, sneezing, runny nose, itchy eyes and cough, which is similar to a cold, so it is allergic to early spring.

Kangminyuan's anti-allergic probiotics are a method to regulate skin allergies from the inside out. There are countless microbial flora on the surface of human skin. Allergens are absorbed by epidermal dendritic cells (DC) connected with IgE receptors, and then they go home and present antigens to skin T lymphocytes, starting an inflammatory reaction. Therefore, the combination of allergen and IgE receptor related to allergy plays an important role in initiating skin inflammatory reaction. This is considered to be the immune cause of eczema-like, urticaria-like, erythrodermic and acne-like rashes. However, when people with facial skin allergy can't get rid of the allergy completely through local anti-allergic protection measures, they can cooperate with the body to supplement enough anti-allergic probiotics Kangmin source, play the role of immune anti-allergic regulation, and enhance the skin mucosal barrier function, thus improving the skin's defense ability against allergens and the environment.
