▲ The product is a good product, but if you are allergic to gluten, you'd better not use it.

If itching and rash persist after use, you should go to the hospital in time. The real diagnosis of allergy depends on allergen detection.

2. Citrus essential oil

▲ Oshadi's copy has a reminder.

If you are using these essential oils, remember to store them in the dark during the day.

There are many ingredients in skin care products that will stimulate sensitive muscles, such as essence, propyl paraben (preservative) and coumarin (spice) ... Sensitive muscles must be avoided in time. There are also some effective ingredients, which have a good effect, but also cause certain irritation or exfoliation, barrier damage and other problems to the skin.

For the "unstable" skin during the season change, these stimuli will make your face worse. We have always said that "skin care means that prevention is greater than improvement". Actually, everything is. Don't try efficacy skin care products easily when changing seasons!

If some products are used for a long time and there is no discomfort in autumn and winter, they can continue to be used. Just remind everyone that you should be careful to buy and replace skin care products in spring. You can wait until May to use effective products.

1. Alcohol skin care products

Including but not limited to various sunscreens (especially Japanese sunscreens) and Japanese lotions.

Alcohol is added to the product, on the one hand, to dissolve the active ingredients, on the other hand, to dissolve some lipids in the skin, open the barrier channel and help the active ingredients to be absorbed.

There is a lot of oil in the skin, and alcohol will not be too much burden, but it should be used with caution for dry skin and sensitive skin! The dryness in winter has not been reversed, and the products with high alcohol concentration will only become drier and drier, which is not good for the skin barrier.

2. Acidic skin rejuvenation products

Especially common acidic products such as fruit acid and salicylic acid. Modified fruit acids such as lactobionic acid (not lactic acid) and gluconolactone are excluded. Please refer to the following products for details.

"Acid" is naturally a good skin rejuvenation product, but the principle of skin rejuvenation is to quickly exfoliate and make the skin tender. The skin is dry, sensitive and unstable, and it is easy to damage the skin barrier because of exfoliation. Don't toss at this time.

3.？ Prototype VC product

Especially for the prototype VC, the name of the ingredient list is "ascorbic acid", and there are no other words behind it. Products are commonly found in professional skin care brands such as Beauty Branch and Obagi.

Generally, there will be a special logo on the bottle: XX% L- ascorbic acid (XX% L-VC) and so on.

VC is super cow, high-concentration prototype VC is more cow, and there is nothing to say about its efficacy.

However, the pH value of prototype VC products is mostly less than 3, which is much lower than the pH value of the skin itself (probably not more than 6), which will soon cause skin tingling and redness. Don't use it casually unless the skin is resistant.

For example, the components of AA2G, VC-IP and other derivatives are not counted, and the irritation is not very strong. It is estimated that some people will ask Kiehl's transparent bottle whitening balance brightening freckle essence, which is the VC derivative used. But the overall formula is not suitable for changing seasons, so wait and see!

4.？ Alcohol products

Alcohol a, also known as retinol. Super anti-aging ability, but irritating to the skin!

At the initial stage of using alcohol A, most people will inevitably have peeling, dryness, tingling and acne increase, which are normal intolerant reactions of alcohol A. ..

If you use alcohol A all the year round, you won't be intolerant for a long time, and you can continue to use it.

If you are sensitive to muscles and have dry skin, you have just started using alcohol A recently, or you already have intolerance. It is recommended to pause, moisturize and repair, and wait until the season changes.

There is no need to buy it

1. mite spray

It's no use counting one!

Mites can cause skin and respiratory allergies, but their feces and corpses are also allergens. Even if the spray is useful, it can only kill mites and can't remove other things. Allergens still exist.

It is best not to dry or beat the quilt indoors. Dust and mites are photographed in indoor air, which is more likely to cause respiratory allergies.

The really effective way is to maintain good hygiene habits and keep these allergens away from us:

Hymn independent dryer can better collect broken hair, dander and pet hair on clothes, and can reduce dust mites, dust and allergens in indoor air.

2. Japanese anti-allergic skin care products

The division between skin care products and medicines in Japan is much more vague than in our country. Many second-and third-class drugs can be bought in local pharmacies, and it is naturally easy to enter China through purchasing, such as:

For example, IHADA is a brand of Shiseido Group, and its products include two or three kinds of medicines (medicines) and external products (skin care products).

Japanese drugstores can sell medicines and skin care products, and some pharmaceutical companies and cosmetics companies will develop and produce products across banks. Many people may think that it is bought by a drug store and belongs to a skin care brand. Naturally, they will think that it is a skin care product. It has been used for a long time.

For example, the drugs we listed include diphenhydramine, lidocaine, ufen, oxazoline benzoate hydrochloride, chlorphenamine maleate ... Do you think the names are hard to recognize? Most of them are anti-allergic drugs, vasoconstrictors and anesthetics, so don't use them as daily care products.

For brands and products that you are not familiar with, don't start blindly without doing your homework, especially those products that are aimed at constipation, headache, allergy and sensitivity in Japan. Fuzzy demarcation will make it easy for you to mistake drugs for health care products.

When collecting information, I saw a question on Zhihu: "How serious can allergies be?"

One respondent @ Jingjing Jingjing, who liked 10000, said: "My cousin's father's comrades knew that my cousin was allergic to seafood and secretly gave him shredded squid, but he didn't come back."

"Allergy" is a strange word for a generation with information occlusion, but it is not for us. Although the boundary between "sensitivity" and "allergy" cannot be clearly explained by ordinary people, the reactions of itching, rash and edema have been one step ahead of them.

For these, timely prevention is the most effective way, I hope everyone can spend this season safely.
