I don’t know when people started talking about the discoloration caused by alcohol. A friend of mine went to a counter to buy skin care products. As soon as the counter lady said that this product contained a small amount of alcohol, she frowned and gave up buying it. And I thought it was very interesting. What's interesting is that sometimes when I go to buy skin care products, some salespersons will take the initiative to emphasize that this water has no alcohol. I feel that many people will use the presence or absence of alcohol to decide or weigh whether to buy this product. Alcohol seems to have become a shady ingredient. So is alcohol really as scary as everyone thinks? Is it really a taboo in cosmetics? Since so many people are unwilling to choose products containing alcohol, why produce them in the first place? And there are still many products that contain alcohol, and some people choose products containing alcohol and use them quite well.
Let’s talk today about whether alcohol contained in skin care products will harm the skin. Is it so terrible?
First of all, not all alcohol smells are caused by alcohol! ! The smell of alcohols and ethers is basically the same as that of alcohol. It is difficult for normal people to distinguish them by smell. For example, ethanol alcohol, such as butylene glycol , caprylene glycol, and caprylene glycol are all moisturizing ingredients.
Secondly, is alcohol really bad for the skin? No, alcohol is a good solubilizer. Some non-water-soluble active ingredients are difficult to dissolve in water. Alcohol can be used to solubilize these ingredients until they are transparent. At the same time, because the high volatility of alcohol can bring a slight cooling feeling when used, it is added to lotion to control oil. And the content is not very high!
What effect does alcohol have in cosmetics?
The main effects of alcohol include the following:
_ | First, it astringes and tightens the skin. The fact that alcohol evaporates easily will bring a cooling sensation to the skin and act as astringent to the skin. |
_ | Second, it has the function of cleaning and removing grease. Alcohol has good solubility and enhances the product's ability to remove grease. |
_ | Third, alcohol can not only dissolve in water, but also dissolve oil and organic matter, and is often used as a solvent in cosmetic formulas. |
_ | Fourth, promote penetration. Alcohol can quickly penetrate the skin to promote penetration. |
How to judge whether a product contains alcohol
In addition to opening the product lid and smelling the smell, looking at the ingredient list of the product is the most intuitive way. Generally speaking, the standard label name of alcohol in the product ingredient list is "ethanol" (or Denatured alcohol), if you see these two words, it means the product contains alcohol. However, other ingredients with the word ethanol cannot be directly identified as alcohol. For example, " phenoxyethanol " is not alcohol, but a safe antiseptic ingredient.
Of course, I am not saying that there are no people who are allergic to alcohol. I am just saying that most people have no need to talk about alcohol discoloration!
I am not encouraging everyone to use alcohol-containing cosmetics. The best way is to choose products that suit you. There are differences between individuals. dry skin and sensitive skin are best to use alcohol-containing cosmetics with caution, because alcohol is not friendly to both skin types, while oily skin has a strong sebum secretion and is not sensitive to alcohol. The buffering power is strong, so you can choose some cosmetics containing alcohol according to your own needs.
