Facial skin allergy symptoms? Who told me?

Skin allergies are also called "sensitive" skin. From a medical perspective, skin allergies mainly refer to when the skin is exposed to various irritations, such as adverse reactions to cosmetics, chemical preparations, pollen, certain foods, polluted air, etc., resulting in redness, itching, peeling and allergic dermatitis on the skin. and other abnormal phenomena. Sensitive skin can be said to be an unstable skin, a skin that is always on high alert. Special attention should be paid to its care. Causes of skin allergies The causes of skin allergies include two major aspects: intrinsic factors and external factors: The intrinsic factor is the allergic constitution itself, which plays a leading role in the onset of skin allergies. Early and complete desensitization is the key to treating skin allergies and preventing recurrence. There are also many external factors. Including factors such as diet, inhalants, climate, and contact allergies. Among them, seafood, protein, spicy food, alcohol, inhalation of pollen, dust mites, cold weather, contact with chemicals, soaps, detergents, etc. are the most common causes of skin allergies. Due to such complex reasons, skin allergies recur repeatedly due to the intertwining of numerous causes and triggering factors. How to take care of skin allergies 1. Stay away from allergens. Because allergy symptoms will always exist and it is impossible to cure them, you can only take precautions at all times to avoid contact with allergens that may cause allergies. 2. Be clear about the skin care products you use and how to use them. Avoid using substances that are strong, overly active and may cause irritation to the skin. Excessive and improper use of powerful cleaning products will destroy the natural protective tissue on the surface of the skin; cosmetics that are too active and accelerate blood circulation can also irritate the skin and cause damage. Do not use soapy lotions such as medicated soap when washing your face. Experts who use surfactants to decompose keratin should avoid this as much as possible. It is best to use emulsion or non-soap soap, which can adjust the pH and adapt to the skin. Products such as scrubs and exfoliants should be avoided. Follow a simple cleansing, toning and moisturizing routine. 3. Pay attention to the use of sunscreen products. Sensitive skin has a thin cortex and is relatively incapable of defending against ultraviolet rays, making it prone to aging. Therefore, it is better to use sunscreen after applying basic skin care products as a barrier. However, the ingredients of sunscreen are also one of the factors that can easily cause irritation. , so it is best not to apply it directly on the skin surface. Recently, some manufacturers have launched sunscreen products with fewer chemical ingredients and physical ingredients, which are relatively less irritating to the skin. At the same time, avoid overexposure, because ultraviolet rays have extremely strong penetrating power, and regular exposure will make the skin thinner and more susceptible to irritation. 4. Use cosmetics with caution. For people with sensitive skin, it is best not to replace the cosmetics you are used to. If you want to use new cosmetics, you should do a skin test first. The method is to apply the cosmetics to be used on the more delicate skin on the inside of the wrist and leave it on. One night or 2-3 days to observe the reaction. If any abnormal reaction occurs, such as inflammation, redness, rash, etc., you must avoid using the cosmetic. 5. People with "sensitive" skin should usually wash their skin with warm water. In areas with flying pollen in spring, they should go out as little as possible to avoid pollen dermatitis. They can use moisturizer in the morning and evening to keep the skin moist and prevent the skin from getting pollen. Dryness and scaling. 6. In terms of diet, eat more fresh fruits and vegetables, and the diet should be balanced. It is best to include a large amount of fruits and vegetables rich in vitamin C, and any food containing vitamin B. Drinking plenty of water, apart from various benefits, also moisturizes the skin in the body. I usually make some homemade nutritional masks, such as cucumber juice mask, loofah juice mask, egg white honey mask, etc., to gradually improve the skin condition and gain skin fitness. 7. Rinse the clothes you carry with you. The detergent remaining in the clothes and towels may irritate the skin. 8. Sleep has beauty effects. Eight hours of adequate sleep every day cannot be replaced by any skin care products. 9. Exercise can increase blood circulation, enhance skin resistance, and enter optimal condition.
