[Health Channel/Comprehensive Report]A woman in her 20s has a rough feeling in her arms and calves when the seasons change, occasionally accompanied by desquamation, often with dry itching symptoms, making it difficult for her to fall asleep. Therefore, I went to the pharmacy to buy anti-itch ointment for a long time. Although it was relieved at first, the dry and itchy skin symptoms did not improve after a few times. Repeated medication made the skin more and more itchy, which scared her to see a doctor.
According to Hu Yixuan, a dermatologist at Jingyan, due to changes in environmental temperature and humidity during the season, many people are prone to redness, itching, chapped, dull and rough skin, which is like a reappearance of wall cancer; while the air is dry and cold in autumn and winter. The skin is prone to dryness and keratin damage due to lack of moisture, and its tolerance to external stimuli will also decrease, causing abnormal reactions such as redness, swelling and itching.

However, long-term use of anti-itch ointment without the instructions of the doctor may cause the skin to become thinner, redden, capillary dilatation, and cause skin damage. Sudden withdrawal may also have a rebound effect, and withdrawal symptoms such as burning and puncture may occur. For pain, redness, swelling, etc., Hu Yixuan also listed 3 wrong skin care behaviors during the change of seasons for the public’s reference:
1. Rub the medicine as soon as the skin is itchy, for fear of rubbing out drug resistance
Although commercially available ointments and medicines can relieve discomfort, they mostly contain steroids. If red and itchy skin is caused by dry and cracked skin, you can switch to products containing “natural plant sterols” extracted from rapeseed to relieve inflammation and itching. It has a deep moisturizing function. Compared with medicinal steroids, it is milder and less burdensome on the skin, suitable for long-term use.
2. Scratching will form a vicious circle
Scratching with external force to relieve itching may cause inflammation, irritation, heat, pain, itching and other symptoms caused by pathogens. Hu Yixuan suggested choosing shea butter rich in vitamins A and E, vitamin B5, amino acids and other moisturizing repairs. The products with care ingredients can alleviate dryness and cracking discomfort caused by weather and scratching, repair damaged skin, improve skin saturation, improve dehydration, and build a healthy stratum corneum for the skin.
3. Excessive bath water temperature can easily cause the skin’s protective power to decrease
There are abundant flora on the surface of human skin, that is, skin microbiome. In this system, good bacteria will inhibit the growth of bad bacteria and protect the human body from pathogenic microorganisms. However, if you take a bath in autumn and winter, Excessive heat may damage the protective power of the sebum membrane, and also make the skin’s oil and water imbalance, affect the original balance of beneficial bacteria, and cause damage to the immune system.
Maintain skin pH5.5, weak acid, environmental protection, healthy sebum membrane
According to foreign studies, every time the temperature drops by 1 degree, the oil secretion of the skin will be reduced by 10%, so the water content of the skin stratum corneum will also be reduced, resulting in dry and sensitive skin. Hu Yixuan explained that when the water content of the skin’s stratum corneum decreases, it will also affect the pH of the skin surface, causing the ecological imbalance of the skin flora, which also weakens the protective power of the sebum membrane.
Hu Yixuan reminded that in addition to bathing with suitable water temperature, you should also avoid bathing products that contain soap and alkali and have too strong cleaning power. It can also create a natural skin ecology with more beneficial bacteria than bad bacteria, so that bad bacteria cannot take advantage of it.
If you want to stay away from cancer of the wall, you can start with daily maintenance. You can choose a pH5.5 slightly acidic shower gel to strengthen the skin barrier, and use mild natural plant sterols to repair damaged skin. You can also apply anti- Moisturizing lotion with dry allergy function, soothe dry redness, sensitive itching, and maintain normal skin physiological functions.
