The difference between allergy and sensitivity
The concept is different
Skin allergy is a kind of skin inflammation, which is an allergic reaction caused by external allergens, mainly refers to the redness, itching, wheals, peeling, etc. caused by external contact with certain allergens.
Sensitive skin refers to a state of hyperreactivity that occurs in the skin under physiological or pathological conditions, mainly on the face, producing symptoms such as burning, tingling, itching and tightness.
The factors caused are different
Allergic irritant: Allergens can be divided into four categories: contact allergens, inhalation allergens, ingestion allergens and injectable allergens.
Sensitive stimuli :
(1) Physical factors: such as seasonal alternation, temperature changes, sun exposure, etc.;
(2) Chemical factors: such as cosmetics, cleaning products, disinfection products, air pollutants, etc.;
(3) Iatrogenic factors: such as topical irritating drugs, local long-term large-term external glucocorticoids, some laser treatment postoperative, etc.
Allergy and sensitivity features
Features of skin allergies
(1): The onset is rapid, and the allergen can be reduced or eliminated after elimination;
(2): There are obvious genetic predispositions and individual differences.
Features of sensitive skin
(1): It looks like thin skin and obvious redness on the face (dilated capillaries).
(2): The skin is easy to redden, the general temperature changes, too cold or too hot, the skin is easy to redden, heat.
How to deal with allergies and sensitivities
How to deal with allergies
If you want to reduce the occurrence of skin allergies, everyone must! Certain! Be sure to stay away from the source of the allergen, after identifying the allergen, stay away from the allergen, which is the most effective way to prevent the occurrence and development of allergic symptoms. Usually patch testing can help identify the source of a contact allergy.
In addition, everyone should also pay attention to regular cleaning of home hygiene in daily life, pay attention to window ventilation, maintain a smoke-free environment, stay away from plush toys and pets, and regularly wash and dry clothes and bedding; Pay attention to your diet and choose alternative foods; Carefully check the food instructions to avoid accidental ingestion; Wear a mask when going out to avoid mosquito bites; Avoid overwork and colds; Be careful with skin care products and medications, unused skin care products should be tested on the skin behind the ears and used all over the face after no risk.
If allergies have already occurred, medication, desensitization therapy, etc. can be used.
How to deal with sensitivity
Develop good skin care habits in daily life, because sensitive skin is accompanied by different degrees of skin barrier damage, hydration + moisturizing + sun protection is the basic principle of repair, and at the same time, everyone chooses non-irritating repair products in daily skin care, do not over-clean, reduce the number of makeup;
For sensitive skin, you can also choose medical beauty projects to improve, such as red and yellow light, which can comfort the skin and repair the skin barrier; Sensitive skin can also use low-energy photorejuvenation to improve skin redness, enhance skin thickness, repair barriers, improve pigmentation, etc.
All in all, sensitivity and allergy are two completely different concepts, and the two can exist at the same time, when these two symptoms occur, we must seek medical attention in time to determine whether it is allergic or sensitive, so that we can better prescribe the right medicine and return the skin to a healthy state.
summary
Allergy is a human immune response, will not resolve immediately, has specific allergens, and will not use any irritants to be allergic, and is innate, can not improve can only avoid contact.
Sensitivity is a neurosensory response that is immediate because of exposure to various stimuli or damage to the barrier, which can be improved by reducing the concentration of the stimulus and removing the irritant or repairing the barrier.
At the beginning, allergic and sensitive skin may be similar, but it will soon feel different – the itchy symptoms of an allergic reaction are much more severe than those of sensitivity.
Regarding sensitivity, in addition to congenital poor tolerance, most of the causes may be impaired skin barrier, which are manifested very clearly:
1. Transepidermal dehydration, very dry skin, peeling, dry itching. The oil skin will obviously dry and oily in the same area, because the sebaceous glands secrete oil while the stratum corneum cannot retain moisture, and it will feel oily and dry.
2. Use skin care products, even if it is not very irritating, it feels intolerant and tingling; When high temperatures, changing seasons, and using new products, the skin will become red and unstable.
Is redness a sensitivity/allergy?
Not necessarily. The very fine capillaries in the dermis layer, when it needs a lot of blood or nutrients, it will expand to meet the demand, but sometimes it cannot regulate the expansion and contraction well, and red blood streaks appear.
There are many reasons for it:
01
heredity
There will be no effect on the skin
02
environment
Plateau or elevated temperature, normal skin reaction
03
There is inflammation of the skin
Capillaries need to transport a large amount of anti-inflammatory factors, causing them to dilate and cause redness
05
allergic
Immune response to allergens
06
Alcohol causes
Alcohol itself is not highly sensitized, but it will dilate the capillaries, so redness and redness will occur
Skin care must first find out whether it is sensitive or allergic, so as to prescribe the right medicine, otherwise the cycle is difficult to do well, especially if the allergy is serious, it may cause irreparable damage to the skin!
