1. DIY fruit acid burns the skin
Fruit acid can accelerate the peeling off of the skin epidermis and improve the roughness of the skin, but it should be handled properly and controlled accurately. If the concentration is too strong, or applied to allergic and dry skin, it will cause burns, skin inflammation, pigmentation and other side effects; The concentration is too thin and has no effect. Therefore, I do not recommend you to use it.
2. Homemade lemon facial mask turns black
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 effect. Therefore, self-made natural whitening has little effect.
3. Self made whitening essence is easy to contain bacteria
A website teaches 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 can be purchased from chemical companies. Mix them well and apply them. Such crude manufacturing is questionable in efficacy, and some ingredients with whitening effect are irritating. In addition, the concentration of effective ingredients contained in self-made 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.
4. 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 Empress Dowager Cixi 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? 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.
5. Take aloe to whiten
Aloe vera can whiten, although it may not be effective, but at least the ingredients are natural and harmless to the body. However, 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? At present, there are only five kinds of aloes permitted by the FDA of the United States and the Department of health of China for edible and medicinal purposes, including: Hope aloe vera, awn aloe vera, Queen’s Brocade aloe vera, African aloe vera, and emerald leaf aloe vera. Aloe Vera has the effect of reducing skin redness and swelling when applied externally, while it has the function of diarrhea and detoxification when taken internally, so as to improve skin dullness or color spots. It is recommended to eat 3 to 4 tablespoons per day. Because the concentration of different brands is different, it is safest to take it according to the label guidelines. Pregnant women should not eat it because of its laxative effect.
