The name 1,4-Benzenediol may be unfamiliar to everyone. If you have a deeper understanding of whitening products and ingredients, you should have heard of “hydroquinone”. Hydroquinone is hydroquinone. The status of hydroquinone for whitening and blemishes is like VA for anti-aging. It is currently a proven gold standard.
Sounds awesome, right? Come and wipe your face with a catty, will it immediately transform into an egg shell! NO! Why do we seldom hear the name of hydroquinone when the ingredients are hot and nicotinamide and VC whitening products are flying all over the sky?
Simply because it’s poisonous.
Hydroquinone has a strong effect of inhibiting the formation of melanin, but it is also accompanied by serious side effects and irritation, and is not stable itself. Hydroquinone is cytotoxic, improper use will “kill” melanocytes, and also cause depigmentation, forming white spots like vitiligo, which is much more difficult to treat than whitening and light spots.
However, in Japan and the United States, the control of hydroquinone is slightly looser. As long as the content of hydroquinone in the United States does not exceed 2%, it can be used as an OTC (over-the-counter drug) or added to skin care products. In Japan, there is also a 4% concentration of whitening essence!
While brands have plenty of data to say it’s absolutely safe, there is technology to stabilize hydroquinone! However, I dare not sell it, and I will not recommend normal and healthy people to buy whitening essence containing hydroquinone on a daily basis! But, the wisdom of human beings is infinite, thanks to the development of science!
Although we can’t control hydroquinone yet, we have discovered a brother of hydroquinone – 1,4-Benzenediol, which can retain most of the “power” of hydroquinone, and at the same time, it is less stimulating, but it is still fierce and not conducive to consumers. “No brain” use.
Therefore, various derivatives of 1,4-Benzenediol have been developed, which are further optimized in terms of irritation and stability, in order to be more easily tolerated by most skins and can be used for a long time. The more common resorcinol Derivatives are: phenylethylresorcinol, 4-butylresorcinol, dimethoxytolyl-4-propylresorcinol, hexylresorcinol. Then today’s topic is officially here, what are these whitening essences with resorcinol derivatives as the main ingredients!
For example, hydroquinone is like A acid, because it has too many side effects and is not allowed to be added in skin care products! However, 1,4-Benzenediol derivatives are like A alcohol, which not only has the powerful effect of mother family, but also is safe and reliable, so for this kind of whitening essence, feel free to use it boldly!
