Which whitening pill works best? White Rabbit Pill, POLA or Huanghantang

Which whitening pills are the most effective? There are endless brands of whitening pills on the market. Which whitening pill is the best and most effective? Let’s take a look together below!

What whitening pills are the most effective?

Every time a whitening product is launched on the market, countless people will try it. After a large number of people have tried it, even if they give up because it “is useless”, the merchant has made enough money and it is time to launch a new product. Therefore, the whitening market can probably be described as "the flags on the city walls are constantly changing" - all the fashionable women have tried various whitening products, and they are almost at the age when they are no longer beautiful and no longer need whitening products.

Cough cough. Now, let’s get back to the topic and talk about “whitening pills”. Some are really effective, while others are very famous but not very effective.

In recent years, a product called "White Rabbit Whitening Pills" has been extremely popular. Just search on the Internet and you'll find the screen full of various purchasing agents and usage experiences. Double Eleven is just around the corner, and without a firm will, it may be impossible to suppress the call from deep in your heart to "buy it and try it."

01

There is no "secret recipe" in whitening pills

According to the company's publicity, taking White Rabbit Whitening Pills can supplement three "functional ingredients" every day, including:

240 mg L-cysteine ​​+ 300 mg Vitamin C + 34 mg Vitamin B5

Are these ingredients rare? No.

Cysteine ​​can be converted from methionine. It is not an essential amino acid and is widely present in various foods. People can obtain more than several hundred milligrams from regular foods every day.

Many vegetables and fruits contain vitamin C. Generally, 100 mg per day is enough for an adult, and people with a normal diet will not be deficient.

As for vitamin B5, there is a lack of sufficient data on how much is needed every day. It is generally believed that a few milligrams are enough. It is also widely present in various foods, so it is difficult for anyone to be deficient in it.

Let’s talk about how much these things are worth. After reading this, you can consider how much this bottle of whitening pills will cost you.

The market price of food-grade cysteine ​​is only more than 100 yuan per kilogram - according to the content in the White Rabbit Whitening Pills, it can sustain a person for more than 10 years. Not to mention vitamin C. A medium-sized orange contains 70 mg. Vitamin C tablets or powder cost only a few dollars a bottle, which is very cheap. The price of vitamin B5 is not much more expensive than vitamin C.

In other words, even if you really want to try the "White Rabbit Whitening Pills", then buy cysteine, vitamin C and vitamin B5 separately, and take them according to the content in the whitening pills. The cost is almost zero compared to the whitening pills.

Of course, the idea behind whitening pills is to "add extra" these ingredients to achieve whitening. Is there any scientific basis for this idea?

The "scientific basis" of whitening pills

One of the amino acids that makes up protein is called tyrosine, which is also a non-essential amino acid. Under the action of tyrosinase, tyrosine in the skin undergoes a series of reactions to produce melanin. This reaction is exacerbated under ultraviolet rays, which is why the skin becomes tanned by the sun. There are two types of melanin, one is called eumelanin and the other is called pheomelanin, and the two are in balance in a certain proportion. If the skin has high levels of glutathione and cysteine, the melanin balance will shift towards pheomelanin and the skin color will be lighter.

The existence of this mechanism makes people believe that eating extra glutathione or cysteine ​​can reduce the production of melanin and achieve a "whitening" effect.

As for vitamin C, it is a classic antioxidant and many people believe that it can eliminate free radicals. By removing free radicals, it naturally helps protect the skin. Vitamin B5 is said to have many functions, but there is no decent scientific basis for this. If put into whitening pills, it can make people feel "powerful without knowing it".

But are these evidences reliable?

Whitening is not something you can do just because you want it

The above "theoretical deduction" is the "scientific basis" of the White Rabbit Whitening Pills. Such "basis" can only be regarded as a "guess". If it is not supported by clinical trial evidence, it will not be convincing at all.

In Europe, a company has submitted an application to the European Food Safety Authority (EFSA) requesting recognition of the functional claim that "cysteine, methionine or both can help maintain the skin." EFSA issued an expert opinion in 2010, stating that “[the applicant] did not provide any human studies to support the claims. The in vitro evidence provided was insufficient to predict that the administration of cysteine, methionine or both would have a protective effect on the skin.”

Of course, for many people, the lack of evidence that it works "doesn't mean it doesn't work" - based on this logic that only applies to debate or arguing, many people are still willing to try it. After all, these things are widely present in regular foods, and regardless of whether they are effective or not, at least there is no safety concern.

Just a waste of money...

Other whitening pills, no matter how high-end plant extracts they use or how glittering technology they use, basically cannot get out of this circle:

There is no clinical trial evidence to prove its effectiveness, but there is no safety issue in taking it.

Are there any whitening pills that are really effective?

have.

This is the effect of Daiichi Sankyo whitening pills. Other whitening drugs that add tranexamic acid (also known as tranexamic acid and hemostatic acid) have similar effects. We're talking about the pink one on the left, not the blue one on the right.

But the one on the left only targets "liver spots", also known as melasma. It may not be effective for other pigmentation.

What about tanning?

you guess?

And did you see the small print in the box: Category 1 medicine.

It's a medicine, so it has side effects.
