How to survive dry winters with dry skin?

Jan 20,2022 | HISEEK PRETTY

The skin has its own set of protection mechanisms. Under normal circumstances, when the ambient humidity is insufficient, the skin's compensation mechanism will be triggered, thereby preventing a large amount of water loss due to evaporation. Especially in winter, this state will reach the extreme, and the skin's "compensation mechanism" is easily "disordered", resulting in "dry scales", making the skin look dull, and the ability to absorb moisturizing products also declines.

For my dry body (especially my limbs) in winter, as long as I perform a simple and rough action of applying body lotion after taking a shower every day, the symptoms of dryness and itching can be relieved.

Not everyone is as easy as me.

We have written a lot about moisturizing in historical articles. I believe everyone has a lot of understanding of the ingredients and mechanism.

This time, we will talk about some neglected details of solving the problem of dry skin or the correct way to do it.

Dry skin, the most intuitive indicator is the lack of water in the stratum corneum.

The epidermis of the skin is from the inside out, and the water content is getting lower and lower. The skin has the ability to absorb water from the air and from the deeper layers of the skin. This ability to absorb water is related to the structural integrity of the stratum corneum. Specifically, it includes the water retention capacity of lipid barriers (composed of fatty acids, cholesterol, ceramides), and the moisture absorption capacity of NMF (containing free amino acids, sodium PCA, lactic acid, urea, etc.).

These also constitute the skin's barrier function. Once the skin's barrier function is damaged, the ability to lock in water and absorb moisture is reduced, so the dryness of the skin will be inevitable.

But why is the skin barrier damaged?

What causes the skin to feel dry?

The reasons for drying are divided into two categories. One is endogenous and the other is exogenous.

Endogenous desiccation
Most of them are related to consumption and malnutrition; renal insufficiency; hemodialysis; suffering from genetic diseases such as ichthyosis Vulgaris, atopic dermatitis, etc. The most common cause of dry skin is skin aging, which often appears after the age of 60 and tends to continue to develop. Environment and lifestyle are important factors aggravating skin problems, such as dry environment or lack of good moisturizing habits.

Exogenous drying
Combination of irritability and exogenous triggers, including contact sensitization of topical formulation components. For example, the use of non-mild cleaning products, such as soap-based body wash, poor quality body wash products, etc. The surfactants in some body washes can dissolve the lipids of the stratum corneum and NMF, causing damage to the barrier and drying of the skin.

So, how to improve the dryness of the body through some hidden details in life and the right skincare habits?

1. Try to stay in a warm and humid place
The air-conditioned environment is also an important cause of dry skin. You can choose to spray some water or use a humidifier to solve the problem of over-drying of the air-conditioned room.

2. Choose a moisturizer
The spray can play the role of instant hydration. However, when there is a lack of water in the external environment, the spray does not have much moisturizing effect, and the use of the spray can easily take away the NMF in the skin epidermis, resulting in dry skin. So you need to follow up with products that lock in moisture, such as oily lotions or creams.

3. Take a bath: wash your face with warm water
The temperature of the bath should not be too high, otherwise, it will easily cause dryness and even sensitivity. In addition to excessive water that can dry the skin, the bath products used in the bath are also an important reason for drying the skin. Time to turn to mild body wash.

4. Correct use of heating equipment
Since the effect of temperature on the skin is so great, the human body close-range heating device in winter (such as the heating blanket, fan heater, electric furnace, etc. mentioned in the previous article) should not exceed 43 degrees when it radiates to the human skin (speaking in human language). That is, you don't get too close to the electric stove, be careful of scalding).

5. Body lotion
It's similar to our selection of facial moisturizers. For hydration, you can opt for some high glycerin body lotion, but make sure the formula is well developed and not too sticky. Everyone's needs for the skin feel of the body lotion are that it is not too sticky, not greasy, and can be absorbed as quickly as possible so that it can be worn without soiling the quilt. Of course, there are many more humectants and moisturizing ingredients to choose from.

A high-quality body lotion product needs to contain humectants, occlusives, emollients, skin lipids, and high essential fatty acid vegetable oils (EFAO). Best to have it all.

6. Pay attention to your diet
Those oils rich in unsaturated fatty acids, such as safflower oil, olive oil, camellia oil, etc., are necessary for a balanced diet. Because the essential fatty acids in these vegetable oils are important components of the human epidermis. And these human bodies cannot synthesize by themselves, and can only be obtained by "eating". Those who go on a diet to lose weight, and children who don't eat meat, are also more likely to have dry skin.

If you do the above six points well, it can be improved to a certain extent
Hope it helps your dry skin through winter. The good news is that the winter is coming to an end, and the beginning of spring is about to begin. I wish you a happy new year.
