Winter is coming, many friends feel that the skin on the body is very dry after the bath, sometimes itchy, what is the problem?
If you want to know, read on!
Wash the skin dry in winter,
Try fixing five errors
1. Do not bathe for more than 15 minutes
Winter bathing, either grinding and rubbing do not want to go, or start, do not want to end easily, because it is too warm!
However, the longer it is washed, the easier it is for the skin to lose moisture and sebum, resulting in damage to the skin's barrier function.

Once this "wall" is damaged, the moisturizing performance of the skin will be greatly reduced, and it will not be able to resist the invasion of bacteria and viruses, which can easily cause itching and even dermatitis [1,2].
In fact, it takes 15 minutes to take a bath in winter, which is just the right time for 3 songs (except for Gu Juji's "Love Song King").
2. The water temperature should not exceed 38 °C
The higher the bath water temperature, the easier it is to take away the moisture and sebum on the surface of the skin, causing the skin to dry out.
If you want better skin, it is recommended to control the water temperature within 38 ° C in the winter bath, that is, it is not hot to the touch, and the feeling is slightly higher than the body temperature [3].
It's warm and doesn't make us feel too dry after washing.
3. Shower gel does not contain these ingredients, easy to be too "fierce"
In addition to not recommending soap, if you have these ingredients in your shower gel [4, 5] (see the ingredient list), the cleaning power is relatively strong, and it is easy to cause dryness:
Sodium lauryl sulfate (sodium lauryl sulfate)
Soap base (as stearic acid, sodium laurate, sodium palmitate)
They are highly degreased and are more suitable for use in the summer, where amino acids and glucoside shower gels can be used as alternatives.
If you take a shower every day, you can even occasionally skip shower gel.
For areas prone to sweating (eg, armpits, buttocks), use shower gel 2-3 times a week, and wash the rest of the area with warm water, which is also clean enough.
4. Rubbing the dead skin every day will make the skin worse and worse
Some small partners take a bath, shower gel is only the basic configuration, high with scrub, but also have to rub vigorously, hate can not rub themselves into a freshly shelled egg as smooth and tender.

In fact, total exfoliation is not good for the skin!
Because, the keratin on the surface of the skin itself will leave on its own.

Daily use of scrub or shower gel with scrub particles will only cause excessive cleaning, damage the skin's barrier function, and cause the skin to become red and itchy [6].
If you have oily skin and really like exfoliation, then go exfoliate once every 2-4 weeks.
If you have dry, sensitive skin, it is best not to use exfoliator products.
5. The older you grow, the more you should apply body lotion
As we age, our skin undergoes a series of changes.
Sebaceous glands and sweat glands begin to atrophy, secretion function slowly declines, moisturizing and protecting the skin less and less oil, the skin will become drier and drier.
In winter, even white dander will fall, and the autumn clothes and autumn pants will shake, and the "snow" will be artificially dropped locally.
So the older you get, the more you should pay attention to skin moisturizing.
In the winter, after taking a bath and rubbing the skin to 70% to 80%, you will start to apply body lotion, and the moisturizing effect will be better [7].
Itching after bathing,
Also be careful with eczema and urticaria
Eczema and urticaria are common pruritus disorders in dermatology [8,9].
The skin with "eczema" is already relatively dry, more prone to itching, and hot water irritation is likely to induce itching attacks.
In addition, some chronic urticaria may also be provoked by excessively high temperatures.
Therefore, if you always itch badly after taking a hot bath, in addition to recommending changing to a warm bath, it is also recommended to go to the dermatology department of the hospital to see, more at ease!
Mastering these, I believe that the skin of the little fairies will get better and better! Take a shower tonight, and remember to sing less!
