Whitening methods Do you know these whitening methods spread on the Internet?

Pearls have been used for medicinal whitening in China for more than 2,000 years. The Compendium of Materia Medica has long recognized pearls as a curative medicine for treating skin pigmentation. The book records: Pearls can remove dullness from the complexion. "An" is the general term for skin patches such as chloasma in traditional Chinese medicine.

Modern medical research shows that pearl powder’s excellent therapeutic effect in treating facial plaques is achieved through adjustments to the entire human body. Scientific research has found that trace elements in pearls can increase the amount of superoxide dismutase (SOD) and enhance its activity. SOD can remove free radicals, improve skin color, and have a whitening effect to a certain extent.

Free radicals are an important factor causing aging. As we age, our metabolism gradually slows down, and our ability to resist free radicals decreases, causing our skin and body organs to age prematurely. Pearl powder itself contains three trace elements, namely manganese, copper and zinc, which are the components of SOD. Applying pearl powder on the face can promote the activity of SOD in human skin, inhibit the synthesis of melanin, and keep the skin white. In addition, since SOD has the function of scavenging free radicals, applying pearl powder on the face can prevent skin aging and wrinkles.

Tips for identifying pearl powder:

1. Products that are extremely white or extremely gray are definitely fake. The color of real pearl powder should be slightly gray. The particularly white ones may have talcum powder added, while the particularly gray ones may be clam shell powder.

2. Real pearl powder should have a faint fishy smell.

3. Take a little pearl powder and spread it on your fingers, then look at it against the sunlight. If you see small shiny dots on it, then the pearl powder is not very authentic, because the shiny substance inside is mica.

4. Take a transparent cup and fill it with some vinegar. Take a little pearl powder and pour it into the vinegar and shake it. If there is no reaction, it is fake. If real pearl powder is put into vinegar and small bubbles appear in the vinegar, it means that the ingredients in the pearls react with the vinegar and it is real.

5. Burn it with fire. Take a small amount of pearl powder and put it in a flat porcelain dish. Then burn the pearl powder with fire. Observe the color and smell of the powder at this time. If the powder turns black and still has a smell, it is fake. If the powder turns gray after burning and has no odor, then congratulations, you have bought genuine pearl powder.

2. There is no scientific basis for the claim that applying milk on the face can whiten the skin!

There is no scientific basis for the claim that applying milk externally can whiten your skin.

1. Milk is easily infected by external bacteria and deteriorates. If used carelessly, it may cause adverse reactions on the skin, or even allergies.

2. General water-soluble substances are difficult to be absorbed by the skin and also contain irritating ingredients.

3. The process of making your own milk mask is complicated and time-consuming, and is far less hygienic and convenient than current masks.

4. Neutral and oily skin may be more susceptible to allergies and acne due to applying milk. If you have acne on your face, you should not apply milk on your face, as it will aggravate the condition and cause more complicated skin diseases.

5. There are nearly twenty parasitic microorganisms on the skin. Food beauty ingredients such as milk are their best source of nutrition, which will undoubtedly cause an imbalance of microorganisms and lead to skin diseases.

3. Washing your face with white vinegar cannot whiten your skin!

White vinegar has no whitening effect. Vinegar can mainly kill bacteria and exfoliate, making the skin smooth, but avoid direct contact with the face. When washing your face with vinegar, put 7-10 drops in the basin. Splash the vinegar and water on your face or immerse your face in a basin. After about a minute, pour out the water and start washing your face as normal. Not recommended for people with sensitive skin. Suitable for people with heavy keratin and more dead skin on their skin. It is best not to do it more than once a week, otherwise the skin's cuticle will become too thin and sensitive.
