As early as thousands of years ago, during the Zhou Dynasty, people began to bathe with rice water, and in the Qin and Han dynasties, it was found that using soap horn to wash clothes and wash hair was very effective.
However, ordinary people still use rice washing water for bathing, and some also use more convenient and easily available plant ash.
Since the Western Jin Dynasty, wealthy people began to use bath beans for bathing, which is a washing powder with bean flour as the main raw material.
In the Southern Song Dynasty, there was soap, named "soap group", and the soap at that time was made of soap pods.
Modern soap was invented abroad and was first brought to Guangzhou in China by the United Kingdom in 1842.
Nowadays, the washing products used for bathing are mainly soaps and shower gels, and if there is no need to pursue a refined life, soaps and shower gels are suitable for anyone to take a bath.
It's just that when you don't choose the right one, either you can't wash it cleanly, or your skin is uncomfortable after taking a bath, and you can just do it.
However, modern people pursue a high-quality lifestyle, and whether to use soap or shower gel for bathing should be particular.
Dry skin and normal skin should choose a shower gel bath
The body wash is mild, without irritation, and the foam is rich when rubbing, which can increase the atmosphere of the bath. Especially for dry skin after bathing, it can be washed cleanly, with less degreasing, and the skin is not dry or tight after washing.
In addition to the washing function, the shower gel also has the function of emollientizing and beautifying the skin, and the skin is smooth and soft after taking a bath, as if you have just finished massaging and pushing oil. If you use body wash for a long time to take a bath, your skin will become smoother and smoother.
Soap has a strong ability to remove stains and is easy to clean oil stains, so people with oily skin should choose soap for bathing.
Since the advent of shower gel, people have found that some people do feel uncomfortable when they take a bath with soap, such as the following 3 types of people, who are not suitable for bathing with soap.
1. People with dry skin
Soap is an improved product of soap, the main ingredients are fatty acid sodium and surfactants, which is often alkaline, stronger than washing grease stains, and is very suitable for oily skin.
However, it is not suitable for dry skin, although it has a strong decontamination ability, but when taking a bath, it takes away a lot of oil on the surface of the skin, making the already dry skin even drier, resulting in itching and even peeling.
Especially in the winter when the weather is dry and dry, bathing with soap often causes the skin to lose its oily protective layer, which is susceptible to cold invasion and disease.
Therefore, it is best to use shower gel for people with dry skin to take a bath.
2. Patients with skin diseases
Some skin diseases are caused by fire, which is called "heat evil" in Chinese medicine, and some skin diseases are inflammation caused by germs.
The soap is more alkaline, which is more irritating to the skin with heat evil, and will aggravate the hot feeling of the skin. For skin diseases caused by germs, the alkaline environment is more suitable for the growth and reproduction of germs, and the pH range of shower gel is generally between 5.5-7.0, even if it is alkaline shower gel, its pH value is much lower than that of soap, so the sterilization effect is much better.
3. People with allergic skin
Some people have skin allergies to alkaline substances, and if you take a bath with soap, it will cause allergies and induce other diseases, so you should avoid using soap, even if you wash your face and hands.
