Including some cosmetics, and in fact, the causes of allergies are extremely complex, and it is important to find out the root cause in order to better fight allergies. What causes skin allergies? During the change of season, the skin often appears dry, itchy, peeling, red spots and other allergic symptoms. In fact, besides being affected by the environment and climate, it is more precisely related to dry skin, age, food, cosmetics, certain substances in the air and so on. Very often, allergies are not just skin symptoms, but the following conditions are also telling you to prepare to do allergy prevention work Respiratory: continuous sneezing, runny nose, nasal congestion, nasal itching, recurrent coughing, chest tightness, wheezing, difficulty breathing, etc. Skin: rash, itchy skin, skin edema, etc., appearing all over the body or localized skin.

Skin allergy OR sensitive skin? It is important to know that skin allergy and sensitive skin are not the same. Sensitive skin is divided into congenital and acquired. 1, congenital caused by genetics, usually thin epidermis, dermis blood vessels are obvious, cheeks are easily congested and red, as long as encounter internal or external stimulation or excessive rubbing, the face will have a reaction. 2, Acquired due to stress, abnormal lifestyle, environmental pollution or excessive application of acid maintenance products and other acquired factors, and easily sunburned. The skin allergy is a dermatitis symptom caused by the combination of external allergenic substances and body antibodies. Such as eating seafood, alcohol and certain fruits and other irritating foods; airborne smoke, ultraviolet rays, pollen, dust, etc., but also may be cosmetics in the fragrance, chemical preservatives, etc.. In addition, the change of seasons, excessive stress or fatigue can also cause allergies. (It is recommended to check the allergens.) Skin allergy, dry skin and acne during the change of season? The main reason for these problems during the change of season is that the skin does not adapt to climate change and the skin itself does not adjust to it leading to severe dehydration! This time must be gentle cleansing, a lot of moisturizing, simplify maintenance, and refuse makeup. Special reminder: never use chemical cosmetics and masks containing hormones, otherwise the effect will be counterproductive! Next, we will continue to tell you a full set of skin seasonal allergy care methods to make your skin easy for the winter! 1, cleaning Use only water (warm water) to wash your face, below 35 degrees is appropriate. Refuse to use cleansing milk cleanser, as long as the cleanser, certainly more or less will destroy the skin itself oil, it is best to temporarily stop using, and carry a bottle of moisturizing spray containing soothing ingredients to calm the skin (must not easily replace the skin care products! If you must change, it is recommended to change the first day after the period, when the skin is more tolerable and can reduce the probability of allergies). 2, sunscreen Allergy those days, if the sun is not very strong, morning and evening when you go out without sunscreen, because even if there is sunscreen without removing makeup, you also need to wash with a cleanser. If you must go out during the day and UV rays are very strong, then it is better to protect yourself from the sun (sunglasses, hats, parasols)! Try to avoid prolonged exposure to high temperatures, excessive sweat secretion will make the skin dry, blood vessels dilate and pores increase. 3, moisturizing The most obvious reason is one: the skin is dehydrated! That is to say, the skin needs so much water, but you give far from enough, so what is the result? Dryness, tightness, peeling! This step of hydration is the key to fight against allergies, regular lotion and hydrating essence at this time are not much effect, can only rely on the mask to first aid. After three days of applying a sheet hydrating mask, I washed my face with water at night, first shot some natural, hydrating and mild skin care water (should not use nutritional skin care products containing drugs, allergic chemicals or animal proteins), then put on the hydrating mask, massage the face to promote the absorption of mask essence, after the sticky feeling disappeared, apply the top cream. 4, diet, sensitive skin to pay special attention to nutritional balance, can eat more milk, soy products and fresh vegetables and fruits to enhance skin resistance, rich in vitamin C fruits and vegetables, pears and kiwi fruit is preferred. Try to avoid eating fish, shrimp, crab and other allergy-prone foods.
