Hydroquinone is a chemical substance of white, less often light gray or yellow color. The component is distinguished by its whitening effect. Its whitening effect on the skin is due to a blockage of tyrosinase. The latter is an enzyme through which melanin penetrates and stains skin cells.

Research and Side Effects
Hydroquinone is not a harmless ingredient. It has side effects, the most obvious of which is ochronosis. Instead of lightening the skin, on the contrary, it darkens. Sometimes it even shows up on the cartilage, such as the ears. Their skin is thin, and the yellowing of the cartilage is particularly visible.
There was also an experiment on rats. The drug caused benign growths in the kidneys and liver - it transforms into these very organs. But there is no reliable data on the connection with cancerous tumors. In 2006, a review was published stating that use at a standard concentration of 2-4% would not lead to skin malignancies. Another article said the drug played a role in developing mutations in the p53 gene, which protects the body from tumors.
In 2008, the FDA deemed the data from a 2006 review and an experiment on rats insufficient. As a result, it categorized hydroquinone as a drug with questionable effects.
Will hydroquinone stop being used in cosmetics? Not likely. They may be until a comparative analysis comes out that will determine the harm/benefit ratio.
So the motto for the use of this drug is moderation and caution. Service is acceptable in 2 to 4% concentrations in a skin-bleaching product. The optimal course is at most 4 weeks and can be repeated no more often than in a month.
