Experts analyze 5 wrong whitening recipes experts analyze 5 wrong whitening methods

1. Taking pearl powder is a waste of effort

I have heard since I was a child that taking more pearl powder can make my skin white and smooth. Even the Empress Dowager Cixi deeply believed it. It is also reported that a star has a habit of eating pearl powder since she was a child. When she grows up, she also keeps eating 1 teaspoon a week to improve her appearance. Is it really feasible?

Expert analysis: there is no basis for taking pearl powder to whiten in nutrition. We should pay attention to the fact that pearl powder will become inferior due to sea water pollution and other problems, and it is a mineral. For fear of heavy metal residues, it may cause damage to the body. It is not recommended to take it indiscriminately.

2. Take aloe vera for indirect whitening

It turns out that aloe vera can really whiten, although it may not be effective, but at least the ingredients are natural and harmless to the body. There are more than 300 varieties of Aloe Vera. There are ready to eat clothes and natural homemade foods on the market. How should we choose them?

Expert analysis: at present, there are only five kinds of aloe permitted by the US FDA and the Chinese Department of health for consumption and medicinal use, including: Good Hope aloe vera, Aloe Vera Vera, aloe vera queen, African aloe vera, and green leaf aloe vera. External application of aloe vera can reduce redness and swelling of skin

3. DIY fruit acid burns skin

In March 2006, a female college student went to a chemical industry store to buy materials and DIY blended fruit acid for skin replacement. Because the concentration was too high, the skin was burned, leaving the face covered with red and swollen scars and necrotizing the epidermis.

Expert analysis: fruit acid can accelerate the shedding of the skin epidermis and improve the roughness of the skin, but it should be properly handled and accurately controlled; If the concentration is too strong or applied to allergic and dry skin, it will cause burns, skin inflammation, pigmentation and other side effects.

4. Self made whitening essence is easy to contain bacteria

Some websites teach people to make their own whitening essence. The materials include: L-C powder-1g, water-soluble vitamin e-0.5ml, and pure water-9.5ml. These materials are available in chemical companies. Mix them well and apply them. The effect of such crude manufacturing is questionable!

Expert analysis: some ingredients with whitening effect are irritating, and the concentration of effective ingredients contained in self-made skin care products cannot be determined. If the concentration is too high, it will be dangerous. At the same time, the containers and materials used in the production process may also be contaminated by bacteria. In addition, it is impossible to know the shelf life without adding preservatives, so we do not recommend to use it.

5. Homemade lemon facial mask turns black

Convinced of the natural whitening method, the victim often applied lemon to her face, and drank undiluted lemon juice three times a day. As a result, her cheeks were red and swollen, with similar burn marks, and her mouth was severely peeled. As a result, her skin turned black, and she also suffered from stomach pain.

Expert analysis: Although lemon contains a lot of vitamin C, it also contains irritating citric acid, which can easily lead to skin sensitivity and even burn the skin to cause anti blackness or blistering. In addition, food contains mostly dextro vitamin C, not levo vitamin C, which has unstable antioxidant and whitening effects. Therefore, the self-made natural whitening facial mask has little effect.
