I. What is skin allergy? Medically speaking, skin allergy is an immune response, or overreaction, of the body to certain external stimuli, often with self-conscious itching of the skin, producing various rashes, which can be combined with respiratory or gastrointestinal symptoms in severe cases, or even life-threatening! So it is very important to understand the general knowledge of skin allergies, and even more so for those who suffer from skin allergies! Second, the general characteristics of skin allergy disease high incidence rate, accounting for about half of all skin diseases; cause or allergen is not easy to determine; treatment is difficult, easy to recur; lingering difficult to heal, long course; infants and the elderly incidence rate is high. So, is there nothing that can be done when you have skin allergies? Of course not. As long as you take the right treatment method under the guidance of a dermatologist, you can achieve satisfactory results. Misconceptions that patients tend to fall into when treating skin allergies (1) Random medication. After suffering from an allergic skin disease, you choose the treatment drugs at will based on your feelings or usual impressions, or hearsay. (2) Seek medical consultation at random. Any medical discipline has its own rigorous scientific system, and so does dermatology. So seek medical advice from a dermatologist. (3) Lack of basic understanding of the skin allergy you suffer from and frequent changes in doctors or medications. This type of disease is prone to recurrence and the medication is slow to take effect, so consult your doctor clearly in this regard. (4) Expecting too much from the treatment in some cases. Despite the rapid development of medicine, it is far from being able to solve all problems, and the majority of diseases can only be solved within a certain range and limit. (5) Trying to cure the disease “at the root”. Sometimes the rash and symptoms disappear, but once the allergen is encountered, or the allergen is not eradicated, it is easy to relapse.
