Your face turns red when the sun shines? Itchy and painful after using inappropriate skin care products? Will the clothes wearing chemical fiber be red and itchy?

These symptoms don't seem to be skin diseases, but they are really uncomfortable and really affect aesthetics.

Are you also a sensitive muscle with high intolerance? Today, let's learn what sensitive muscles are, how sensitive muscles are formed, and how to maintain and adjust them.

For the judgment of sensitive muscles, a considerable part really depends on "I think".

There are three dimensions for evaluating sensitive muscles. Besides objective skin physiological parameters such as TEWL value, skin pH value and skin erythema index, there are really subjective and semi-subjective evaluations [1]. That is to say,

I feel prickly, itchy and tight after the skin is stimulated.

When answering the questionnaire, I gave myself high marks in skin sensitivity to weather, skin care products, cleaning products, clothes, textiles and rough items;

③ I took part in some irritation tests, and after applying capsaicin or lactic acid to my face, I gave a high evaluation of the stinging degree of my skin, so I am sensitive skin.

Is this arrogant evaluation standard also willful?

In a word, sensitive skin (SS) refers to a highly reactive state of skin under physiological or pathological conditions, mainly occurring on the face. When stimulated by physical, chemical, mental and other factors, the skin is more prone to subjective symptoms such as burning pain, tingling, itching and tightness. [ 1]

First of all, sensitive skin is different from skin allergy.

Skin allergy mainly refers to skin diseases related to immune system allergic reaction caused by human contact with certain allergens, such as redness, itching, wheal and peeling. Mainly manifested as various dermatitis, eczema, urticaria and so on. Specific allergens include things you touch (contact allergens, such as cat hair) and things you inhale (inhaled allergens, such as dust and pollen). What to eat (eating allergens, such as peanuts and beans). ) and needles (injection of allergens, such as some people are allergic to penicillin) and so on. Therefore, skin allergy is an allergic reaction caused by allergens and needs medical diagnosis and treatment.

Sensitive skin has no diseases related to immune system allergy such as dermatitis, eczema and urticaria, but an intolerant and highly reactive skin state.

This high reaction may be caused by many internal and external factors, including cosmetics, sun exposure, psychological stress and so on. Among them, the use of cosmetics is the most common factor.

For example, improper cleanser destroys the normal pH value of skin surface, which leads to or aggravates the weakening of skin protection ability, which may aggravate our skin sensitivity. On the one hand, the skin barrier is damaged, and external stimuli easily enter the skin. On the other hand, peripheral nerves are too sensitive. Under the synergistic influence of these two factors, there are too many local inflammatory factors in the skin, which further leads to the damage of skin barrier and vasodilation. [2]

It has been more than a year since the outbreak of COVID-19 last year, and it seems that masks have long been a necessity in daily life. However, wearing a mask with poor material will also aggravate the symptoms of sensitive muscles-

You should carefully choose masks with qualified quality to avoid the stimulation of materials and should not wear them for a long time. We can take off the mask every once in a while and let the skin relax for a while.

According to the expert knowledge of sensitive skin diagnosis and treatment in China (20 17), the proportion of sensitive muscles varies from country to country: 25.4-89.9% in Europe, 40-55.98% in Asian women and 36. 1% in China. I wonder if you are sensitive to skin after reading this article.

Are you sensitive to voting?

Answer yes! As soon as the sun shines, it is so red that mom doesn't even know it.

B Not at all, I love taking a bath, and my skin is good ~

I don't know, maybe a little sensitive?

After careful consideration, I made a decision against my ancestors-to tell you the secret of keeping sensitive muscles.

Of course, the platitudes of staying up late less, eating reasonably, avoiding spicy stimulation and exercising more are not mentioned.

You won't do it anyway, so let's see what is easy to do:

First, wash your face less and don't be too clean.

Skin care should be reasonable, exfoliating products should be banned, and face should be cleaned with warm water, and the number of times of face cleaning should not be too much every day.

Second, it is simple, and the skin care method is simple.

Repairing the damaged skin barrier is an important measure to treat sensitive skin. Reasonable skin care should follow the principles of gentle cleaning, soothing and moisturizing, and strict sun protection. It is advisable to choose medical skin care products that have been tested and clinically verified and have good safety. Some irritating functional skin care products need to be used with caution.

Well, I'm too lazy to use too many skin care products, and I have found new medical arguments.

Third, see a doctor.

Cold spraying or cold compress is also good for shrinking capillaries.

Irradiate red light or yellow light to relieve treatment,

Even severe symptoms require anti-inflammatory and antihistamine drugs.

What kind of treatment measures are needed depends on the diagnosis and treatment opinions of dermatologists. At this time, I can't "I want to".

I wish you all good skin and no sensitivity from now on.
