In the north, the weather has four distinct seasons. Entering October, the temperature drops sharply and the air becomes drier and drier. This is followed by a large number of people who suffer from skin problems due to improper skin care. In our dermatology clinic, we see a large number of patients with itchy skin and hypolipic eczema. A lot of people to the winter, took off the long Johns dandruff flying around, as if it was snowing, is not good skin care!
Let’s explore the problem of skin care in winter from three aspects.
Why does winter appear easily the skin is dry and itchy?
1,In winter, the external environment is dry, and the humidity is greatly reduced. The moisture content in the air is low.
2,The secretion of sebaceous glands is greatly reduced in winter, resulting in dry skin.
3,Dry skin causes the skin barrier to be damaged, when the itch threshold drops, meaning that dry skin is more likely to itch.
4,Itching leads to scratching, which in turn promotes the release of inflammatory mediators and exacerbates itching, resulting in a vicious cycle of itch-scratching.
Many people like to take a hot bath in winter. The hot water will wash off the sebum membrane on the surface of the skin and lose the protective effect of natural sebum on the skin. In addition, too much water itself can irritate the skin and cause itchiness.
Winter skin care precautions
Do a good job of hydrating, moisturizing, choose the right moisturizer. Winter generally needs to choose more thick or greasy moisturizing cream effect is good, how to choose, the following will be detailed analysis.
Use a humidifier indoors to keep the humidity at about 40-50%.
Choose gentle cleaning products and avoid soaps or cleaning products with harsh surfactants like SLS.
Don’t use exfoliators.
Do not take a bath too often, wash 1-2 times a week. Bath water temperature should not be too hot, should be around 38 degrees, which is close to the body temperature. Bath time should not be too long, no more than 10 minutes each time. Try not to rub.
Close-fitting clothing and bedding should choose comfortable, breathable good pure cotton products, more tight clothing and chemical fiber products can increase the sensitivity of the skin and aggravate itching.
How to choose moisturizing products in winter
We often confuse moisturizers with emollients, but there are some differences.
The ingredients of moisturizers include emollients, hygroscopics and sealants.
Emollients, such as glycerin stearate and shea butter, fill the gaps between keratinocytes and leave the skin soft and smooth.
Hygroscopics such as glycerin, hyaluronic acid, alpha-hydroxy acid and sorbitol actively absorb water to moisturize the skin, similar to the natural moisturizing factors found in keratinocytes.
A sealer, usually an oily substance, that forms a hydrophobic film on the surface of the skin to prevent moisture loss. Common encapsulation agents are petroleum jelly/mineral oil, dimethyl silicone oil, vegetable oil, animal oil and lanolin.
Moisturizers with the right proportion of ceramides, cholesterol and free fatty acids repair the skin barrier, also known as skin barrier repair agents.
In winter, moisturizers of choice include moisturizers, hydrating masks (often containing hyaluronic acid), and moisturizers.
Moisturizers and hydrating masks hydrate your face, especially hyaluronic acid, which can absorb up to 1,000 times its own weight in water. But only hydrating, not locking water is not good. Autumn winter skin is very dry, besides the need to grab moisture from the environment outside still need to lock moisture. The encapsulation agent forms a hydrophobic film on the surface of the skin to lock in water. Accordingly, autumn winter must use the moisturizing frost that contains encapsulation agent ingredient. You can see that by looking at the cost chart on the package.
Of course, different skin types have different degrees of dryness in winter. Moisturizers with encapsulation ingredients are often heavy and greasy. For people with oily skin, lighter lotions are an option. If you don’t feel dry, you can even choose a moisturizer that doesn’t contain encapsulation.
In addition, skin dryness varies from body part to body part. The face, hands and the extensor side of the calf are the areas that need special moisturizing.
