In summer and autumn, the temperature drops gradually, and sometimes suddenly warms up. The temperature fluctuates drastically, and the 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 in order 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 very concentrated skin allergy reactions: redness, rashes, dryness, peeling, itching, etc. We call this “seasonal allergy”. This is a phenomenon we call “seasonal sensitivity”.
”Allergy” or “seasonal sensitivity”?
When the skin is dry, red, itchy, etc., many women say, “Oh, I’m allergic!” when they describe 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.
Most people are not actually allergic, but rather the skin barrier function has failed to adapt in time to the environmental stresses brought about by the change of seasons. Simply put: fall has come and gone, but the skin is still living through summer, thus producing all sorts of uncomfortable symptoms. True allergies would have been a minority of a minority of people as well.
Allergy and sensitivity are two different things. Acquired sensitivity is mainly caused by a decrease in skin barrier function, while allergy is a metamorphic reaction involving the immune system. Although the symptoms of both are superficially similar, the mechanisms by which they occur are completely different.
1. Sensitivity.
When seasonal sensitivity occurs, please first review your skin care methods to see if the skin itself is damaged due to improper skin care, in a thin, translucent, red, sensitive condition, such as washing a face will feel tingling, and after washing the pain disappears, it belongs to the “simple irritation” caused by skin fragility, and not allergies.
As long as you stop these irritating and damaging methods, simplify 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, when the skin repair is complete, tolerance increases, seasonal changes will no longer cause sensitivity.
2. 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.
Change of season skin care.
1, prevention.
Usually eat more fruits and vegetables, drink more water;
Keep a positive and optimistic attitude;
Often hydrate, pay attention to sun protection.
At the same time, you can appropriately choose some mild nature of skin care products, can help protect the skin from external environmental aggressions, quickly soothe the skin, so that the skin feels comfortable and balanced.
2. Treatment.
The most important way to deal with allergies is to rank the allergenic source according to the suspected factors and avoid re-exposure. Generally, after eliminating the allergenic source, the symptoms will disappear automatically in a relatively short time. Of course, a long period of sustained allergy will also cause damage to the skin and eventually become sensitive skin.
For both allergies and sensitivities, the following methods can be used.
① Stop using suspicious cosmetics, irritating methods and products.
②Avoid stimulation, such as hot and cold acidic wind friction sunlight, avoid excessive cleaning.
③ Use chamomile puree, cactus, licorice, horsetail, mung bean and other extract ingredients to soothe and calm, if necessary, seek medical help and use anti-inflammatory drugs.
④After the symptoms have disappeared for a month or two, do a test with the product to distinguish whether it is an allergy or a simple irritation in order to avoid future re-exposure.
If it is an allergy, take care to avoid allergy-causing products and don’t believe in claims like “detoxification” or feel bad about the money and insist on using it up.
If you are sensitive, you should use simple repair products with simple ingredients and strengthen your daily care to let your skin gradually return to normal.
