Which is better, soap or shower gel? Recently, I read an article "Please Bath with Bar Soap" on the Internet, warning you that parabens in shower gel may cause breast cancer. Because it is found in some breast cancer patients, you should switch to bar soap. But another report pointed out that some soaps contain harmful surfactants, which is very interesting! According to these online intellectuals, don't bathe with cleaning products. Bathing with clean water is the healthiest and safest. Alas, I have to say that the more developed the internet is, the easier it is for some "interested" people to confuse readers who don't understand chemical composition! Let's start with parabens. P-hydroxybenzoate is a preservative, and its complete scientific name is P-hydroxybenzoate. There are mp (methyl nipagin), bp (butyl nipagin) and pp (propyl nipagin) according to the different carbon numbers of functional groups.
When many people hear Nipokin, they think of cancer, evil preservatives and black-hearted businessmen! I really must say that preservatives are a necessary evil. A can of rotten products full of bacteria without preservatives is definitely more terrible than products with preservatives. There is no absolutely safe preservative in the world. Parahydroxybenzoate is controversial, but not necessarily carcinogenic, but long-term exposure to high concentrations may cause skin allergies. At normal concentration, parabens are basically a relatively safe and effective preservative system, especially in products that are washed off immediately after contact, such as lotions and detergents.
Take a bath with shower gel every day, can you absorb excessive p-hydroxybenzoate to cause cancer? Of course not! Paraben's claim that it causes cancer has not been confirmed, and the time that the shower gel contacts the skin is quite short. In this process, the amount of parabens that will enter your body is almost zero, so don't worry that "parabens in shower gel will cause cancer". If you are worried about causing allergies, remember not to take a bath with too high water temperature, and don't let the shower gel stay on your skin for too long. Basically, there will be no problem.
After the shower gel is clear, some people will question the "surfactant" in soap or detergent. There are reports on the internet that surfactants are toxic, and industrial synthetic surfactants will accumulate in the human body and cannot be excreted ... What is a "surfactant"?
Simply put, surfactants are ingredients that can pull water and oil together. Water and oil are originally immiscible, but in order to achieve the cleaning effect and let the water wash away the oil, it is necessary to rely on surfactants. Whether it's excess sebum secreted by the face, greasy hands after eating, dirt on clothes ... as long as it needs cleaning, surfactant is the role of pulling oil into the water.
So, what are the surfactants? Of course, soap and synthetic surfactants in general cleaning products are all. Don't believe the nonsense that "natural handmade soap contains no surfactants". Of course, it also has surfactants. In addition, in fact, egg yolk is also a surfactant! Mayonnaise for salad and cold bamboo shoots in summer is emulsified and mixed with vegetable oil, water, vinegar and egg yolk.
There are many doubts and concerns about the synthesis of surfactants. Let's see if it is reasonable one by one. "Synthetic surfactants can penetrate cell membrane, destroy cells and denature protein."
Yes, surfactants can indeed destroy the cell membrane and denature protein. The question is, will your cells come into direct contact with surfactants? The surface of human body is protected by stratum corneum, so it is impossible for cells to directly contact surfactants.
"Surfactants will accumulate in the body and destroy your body."
Well, every time I see this argument, I laugh. I can't say "100% surfactant can't enter the body", but how much? Unless you take a bath with pure surfactant every day, or use shower gel as body lotion every day, you really don't need to worry about such things.
"Surfactants are environmental hormones that will destroy the environment and ecology."
Nonylphenol surfactant (NPEO, nonylphenol polyoxyethylene ether alcohol) and the residue of nonylphenol (NP, also called nonylphenol) after decomposition in nature are indeed an environmental hormone, which will cause damage and influence to the ecology. At present, it has been banned in household cleaners, but many clothes and fabrics will still be used during processing. This really needs everyone to realize that for the sake of ecology, do not use detergents containing NPEO.
In addition, I also want to remind everyone that it is wrong to be too slippery or too astringent after washing your face and taking a shower. Too slippery means that the emulsion remains on your skin surface, while too astringent means that the cleaning power is too strong and the sebum is removed excessively, which may lead to dry and red skin and even skin inflammation.
Conclusion Chemical components are ubiquitous in daily life, and skin will definitely come into contact with cleaning products every day. Just be careful that these cleaning products don't stay on the skin for too long, don't over-clean, and don't pursue the slippery feeling after washing. Then identify the components and reject NPEO. Whether you use shower gel or soap, you can wash pengpeng with peace of mind!
What's the difference between soap and shower gel? First, suggestions: use shower gel for dry skin, soap or shower gel for neutral skin, and soap before shower gel for oily skin.
Second, then the explanation of soap and shower gel: the first is the classification of shower gel. One is moisturizing and the other is refreshing. As the name implies, the first kind feels slippery after washing, and the latter is very refreshing after washing (the refreshing degree depends on what brand you use), just like washing your face with oil-controlled facial cleanser.
Compared with shower gel, soap is a strong base, which has a good effect on both decontamination and deoiling. However, as we all know, the oil layer on the skin surface has the function of water retention. If this oil layer is washed too clean, the skin will be dry before it is reformed, and a lot of oil will be secreted in the dry body. Doing this repeatedly will aggravate the oiliness of the skin to some extent.
Third, let's talk about the difference between soap and shower gel: summarizing the second item, we can easily draw a conclusion that soap has a better cleaning effect and shower gel has a stronger nursing effect.
Fourth, let's talk about the division of oily skin. Skin is generally divided into four categories: dry skin, neutral skin, oily skin and mixed skin. (See "How to classify our normal skin" for details. In fact, there is no obvious limit to the degree of oiliness. Which category we belong to is only a rough idea, and the specific degree varies from person to person.
Fifth, finally answer the question: dry skin is short of water, so naturally it is better to use moisturizing shower gel.
The skin quality of neutral skin is between the front and back. Please refer to the former and the latter for details, and adopt a compromise method according to your actual situation.
Oily skin is very troublesome, and it is not easy to clean up the dust on the skin surface. Needless to say, moisturizing and controlling oil is also a big problem. My suggestion is to wash with mild soap first, and then use shower gel. Dry after washing, refreshing and comfortable. As for what shower gel to use, it is said that it varies from person to person. Anyway, my skin is oily, and I usually use refreshing shower gel)
Mixed skin is the most troublesome, simply speaking, it is the mixture of the first three (or both), and how to choose it should be adapted to local conditions.
