377 (phenylethylresorcinol) – The new favorite whitening brand

    Today we’re going to talk about this whitening ingredient called web celebrity — 377. It is believed that now we are familiar with the composition of phloroethylresorcinol, which can be said to be one of the most widely used and most effective materials in the derivatives of phloroethylresorcinol.
    It should not be confused with hydroquinone (hydroquinone) and Kanboo alcohol. Hydroquinone is not used in cosmetics in China, and rhododenol has also been involved in white spot events, making Kanboo a quick flop. To make the distinction, let’s look at the following diagram.
    Before first learned about this component after, just at that time in Thailand, the empress is out of a beautiful day cream looks like toothpaste, boasts a clean white because there’s some titanium dioxide in (), and 377 of the most popular whitening ingredients at the same time, when a impulse, I bought two boxes of wanted to try, so cheap, after all, still contain 377, more cost-effective.
    The result that skin feeling is really touching, it is simply rub mud bath treasure. Milk body is white, can rub the color on the clothes and the foundation rub clothes. So after using it twice, it sits there forever (skincare is a very subjective and personal experience). Although we have stepped on thunder, due to the high efficiency of this ingredient, basically all the major brands have gradually replaced this cow Bee ingredient, but this ingredient will bring a lot of problems in the application. Let’s talk about it.
    First of all, Symwhite 377 is just a registered patent trademark of Dexin Company. In fact, many domestic and foreign raw material manufacturers have developed the raw material of phenethyl-resorcinol, but the trade name is not the same, the name of the ingredients are the same. The reason why phenethyl-resorcinol has a good role in improving skin color, one of the key points is that it has a bisphenol structure, such as the familiar hydroquinone, resveratrol are components with bisphenol structure, can play a role in the competitive inhibition of tyroginase, so gradually improve skin color.
    And phloroethylresorcinol has a bisphenol structure, so it is also a strong antioxidant, which has a good antioxidant effect. The downside is that antioxidants are known to protect others at their own expense, so phloroethylphechol, if not formulated with other antioxidants and color protectants, is prone to discoloration.
    In a nutshell, the phenylethylresorcinol effect is effective both in vivo and in vitro. This is despite the fact that each raw material company has demonstrated low allergenicity and safety at high rates with patch tests. However, this whitening ingredient is not so friendly. Because it has a problem with the application, which is the tingling. Phloroethylresorcinol is used in cosmetics to make people with poor skin barriers feel a short-term tingling sensation, but it is not caused by allergies, it is purely irritating.
    And to talk about tingling, you have to mention the way that phenethyl-resorcinol is dissolved in cosmetics.
    The first is a polar oil solution with good permeability, which allows phenethyl-resorcin to penetrate into the skin and play its due role. But to ease the sting, it is often made into a thick cream;
    The second method is to dissolve with diols, which has the advantage of reducing the tingling sensation, but also reduces the permeability of phenethyl-resorcin, which is easy to precipitate on the skin surface, resulting in poor final effect.
    So the products currently on the market are either emulsified in a thick way or in an alcohol-soluble way. Therefore, if the consumer is conscientious enough to add 0.5% to the highest standard in China, he/she must be psychologically prepared for the possibility of a short period of tingling. The normal skin basically reflects a weak tingling sensation in the range of 0.1%~0.3%.
    All in all, if you want to buy A product with phenylethylphechol, it’s best to be psychologically prepared, especially if you have A poor skin barrier, so build tolerance slowly, just as you would with cosmetics that contain Alcohol A.
    Still repair skin barrier well so, have healthy skin barrier ability to have good-looking skin only, ability USES protect skin to taste to add on the icing on the cake, after reusing effect of this kind of product can be better certainly.
