There is a cosmetic manufacturer that mixes anything that is trendy.
Be especially careful with hydroquinone-containing cosmetics.
Clinic affiliates sometimes don't mix hydroquinone with high effectiveness against spots, sometimes patients andDoctor's cosmeticsAsked by loyal people.
The reason is simple.
Hydroquinone is supposed to be taken as a pharmaceutical product, and it is easy to oxidize, and the safety of its formulation in cosmetics has not been confirmed.
Hydroquinone is 100 times more effective than arbutin (speaking in a test tube), and there are some people who are using it with their eyes on safety, with the topic being preceded.
In the past, use in cosmetics was prohibited in Japan, so it was only used in some dermatologists to treat spots.
It is a very unstable substance, and when it is simply dissolved in water, it is immediately oxidized and turns brown.
When blended with cream, it changes to a pink color, so it is a difficult ingredient to ensure stability.
Originally banned in Japan because no manufacturer provided safety data to the Ministry of Health and Welfare.
However, after the relaxation of regulations on cosmetics in 2001, hydroquinone cosmetics were introduced because it was possible to use other than pharmaceutical ingredients and some prohibited ingredients even if there was no safety data. However, cosmetic manufacturers have not confirmed safety.
Of course, because it is highly toxic, there are many countries that have restrictions on hydroquinone, and in the United States it is written on cosmetics to stop if it is not effective after 3 months of use. Even in Europe, where cosmetic relaxation is advancing as in Japan
Hydroquinone is designated as a prohibited ingredient to prevent foreign imports. In Japan, the situation is very vague, and there is no cautionary statement about hydroquinone on cosmetics.
If it is hydroquinone to be used under the supervision of a specialist, the specialist can objectively judge and advise you to stop using it, but if it is formulated in cosmetics, there are no notes like American cosmetics, Isn't it the reality to continue to use it forever?
In other words, there is definitely a problem with using hydroquinone, which has been oxidised in a casual manner, as a cosmetic.
This is the reason why major cosmetics manufacturers forgo the combination.
Hydroquinone is highly toxic when oxidized, so it can only be used safely if it is a product of a company that makes cosmetics with an emphasis on stability. Rather, hydroquinone should be treated as a medicinal product used under the doctor's prescription.
By the way, the whitening effect of hydroquinone exerts its power by suppressing the action of tyrosinase and preventing small melanin from sticking together to become large melanin (preventing polymerization of melanin).
Unfortunately, hydroquinone is effective in its effective amount (whitening) and side effect (stimulation), so it is certainly powerful, but it also has a heavy burden on the cells. There is none.
Isn't it surprising that Europe is banned?
It seems that the United States is considering tightening regulations. I would like women to have a solid knowledge of cosmetics so that they do not become a prey for a company that follows a profit-oriented fashion that ignores safety.
