Redness, rash, dryness, peeling, itching – allergies or seasonal sensitivity, do you know the difference? In summer and autumn, the temperature gradually drops and sometimes suddenly warms up again. The temperature fluctuates drastically, and cold and warm air exchange frequently. When it is hot, the capillaries expand and the rate of water loss from the skin accelerates; when it is cold, the body compensates for the expansion of blood vessels to maintain blood supply and body temperature, and the permeability of blood vessels increases (immune cells become more active). Humans have the ability to adapt to environmental changes, but there is always a lag period in the response. It has been established that the oil secreted by the skin (sebum) together with the intercellular matrix (especially ceramides) form the chemical barrier of the skin. When they are reduced, the skin barrier will weaken. Recently, a significant number of girls have been experiencing a very high concentration of skin allergies: redness, rashes, dryness, peeling, itching, etc. We call this “seasonal”. This is a phenomenon we call “seasonal sensitivity”. When the skin is dry, red and itchy, many women say, “Oh, I’m allergic!” when describing it. .”. However, when asked for details, such as whether they have recently changed any skin care products or been exposed to any allergens, they find that there is nothing unusual. Allergy or “seasonal sensitivity” Most people are not allergic, but the skin barrier function is not able to adapt to the environmental stress caused by the change of seasons. Simply put, fall is here, but the skin is still living through summer, thus creating all kinds of uncomfortable symptoms. True allergies would have been a minority of a minority of people as well. Allergies and sensitivities are two different things: Sensitive refers to skin that is more fragile, has an imperfect keratin barrier and is poorly tolerated. Allergy is a kind of allergic reaction, in which allergens enter the body, prompting the body to produce the corresponding antibodies, triggering an antigenic antibody reaction, manifesting as erythema, papules, pimples and other clinical objective signs, often accompanied by itching. Allergy When seasonal sensitivity occurs, please first review your own skin care methods to see if your skin is damaged by improper skin care and is in a thin, translucent, red and sensitive condition, for example, if you feel tingling when you wash your face and the pain disappears afterwards, it is a “simple irritation” caused by fragile skin and not an allergy. As long as you stop these irritating and damaging methods, simplify your skin care and pay attention to protection, it is easy to get relief, but it takes 3 months or even a year to fully repair, and when the skin repair is completed, the tolerance increases and seasonal changes will no longer cause sensitivity. Allergies If your own skin condition is healthy and intact, and you are not allergic or have little history of allergies, consider whether it is an allergy. Skin care during the change of season Eat more fruits and vegetables and drink more water; keep a positive and optimistic attitude; hydrate frequently and pay attention to sun protection. At the same time, you can appropriately choose some mild skin care products that can help protect your skin from the external environment and quickly soothe your skin, making it feel comfortable and balanced. The most important way to deal with allergies is to identify the allergens according to the suspected factors and avoid re-exposure to them, and generally the symptoms will disappear automatically in a short time after eliminating the allergens. Of course, prolonged and persistent allergies can also damage the skin and eventually turn it into sensitive skin. Whether it is allergy or sensitivity, the following methods can be used: moderate cleansing is the key to maintaining sensitive skin, because dirt in the pores is also the bane of allergy inflammation.
