Why does my face itch after using facial cleanser

Basically everyone has used facial cleansers, but everyone's skin type is different, so you must be careful when using facial cleansers and choose different facial cleansers according to different skin types. Some people will have some reactions on their faces after using facial cleansers, such as small red spots and itchy skin. Once this happens, stop using the facial cleanser immediately. This is mostly caused by an allergy to the facial cleanser. The most common phenomena are redness, itching and peeling, so you should pay special attention when choosing a facial cleanser.

Causes of skin allergies

The causes of skin allergies include internal factors and external factors:

The internal factor is the allergic constitution, which plays a leading role in the onset of skin allergies. Early and thorough desensitization is the key to treating skin allergies and preventing recurrence.

There are many external factors as well. Including diet, inhaled substances, climate, contact with allergens and other factors. Among them, seafood, protein, spicy food, alcohol, inhalation of pollen, dust mites, cold weather, contact with chemicals, soaps, detergents, etc. are the most common causes of skin allergies. Due to such complex reasons, skin allergies recur repeatedly due to the interweaving of numerous causes and inducing factors.

How to take care of skin allergies

1. Stay away from allergens. Because allergic symptoms will always exist and cannot be cured, you can only be careful at all times and avoid contact with allergens that may cause allergies.

2. Be clear about the skin care products you use and how to use them. Avoid substances that are highly effective, overly active, and potentially irritating to the skin. Excessive and improper use of strong cleansing products will damage the natural protective tissue on the surface of the skin; overly active cosmetics that accelerate blood circulation can also irritate the skin and cause damage. Do not use medicated soap or other soap-based lotions when washing your face, because surfactants are good at decomposing keratin and should be avoided as much as possible. It is best to use an emulsion or non-soap soap, which can adjust the acidity and alkalinity to suit the skin. Products such as scrubs and exfoliants should be avoided. Follow a simple cleanse, toner and moisturizer routine.

3. Pay attention to the use of sunscreen products. Sensitive skin has a thinner skin layer, has less defense against ultraviolet rays, and is prone to aging. Therefore, it is better to use sunscreen after applying basic skin care products as a barrier. However, the ingredients in sunscreen are also one of the factors that can easily cause irritation, so it is best not to apply it directly on the skin surface. Recently, some manufacturers have launched sunscreens with fewer chemical ingredients and more physical ingredients, which are relatively less irritating to the skin. At the same time, avoid excessive exposure to the sun, because ultraviolet rays have extremely strong penetrating power, and frequent exposure to the sun will make the skin thinner and more susceptible to irritation.

4. Use cosmetics with caution. For people with sensitive skin, it is best not to change the cosmetics you are used to. If you want to use new cosmetics, you should do a skin test first. The method is to apply the cosmetics to the delicate skin on the inside of the wrist, leave it on for one night or 2-3 days to observe its reaction. If an abnormal reaction occurs, such as inflammation, redness, rashes, etc., you must avoid using that cosmetic.

5. People with "sensitive" skin should use warm water to wash their skin more often. In areas where pollen is flying in the spring, they should try to reduce going out to avoid pollen dermatitis. They can use moisturizer in the morning and evening to keep the skin moisturized and prevent dryness and flaking.

6. In terms of diet, you should eat more fresh fruits and vegetables, and have a balanced diet. It is best to include a large amount of fruits and vegetables rich in vitamin C, and any food containing vitamin B. Drinking plenty of water, in addition to various benefits, can also moisturize the skin internally. You can make some nourishing facial masks at home, such as cucumber juice mask, loofah juice mask, egg white honey mask, etc., to gradually improve skin condition and achieve healthy skin.

7. Rinse your clothes thoroughly. Detergent residue in clothes and towels may irritate the skin.

8. Sleep has beauty benefits. Eight hours of sleep a day cannot be replaced by any skin care products.

9. Exercise can improve blood circulation, enhance skin resistance, and put the skin into optimal condition.
