Is the folk whitening remedy credible?
1. DIY fruit acid burns the skin
AHA can accelerate the skin's epidermis and improve the roughness of the skin, but it should be handled properly and time controlled accurately. If the concentration is too strong, or if it is applied to allergic and dry skin, it will cause burns, and it may cause side effects such as skin inflammation and pigmentation; if the concentration is too thin, it will have no effect. Therefore, it is not recommended for everyone to use.
2. Homemade lemon mask to black face
Although lemons contain many vitamins C, they also contain stimulating citric acid, which can easily cause skin sensation and even burn skin to cause blackening or blisters. In addition, the food contains a lot of vitamin C, non-L-Vitamin C, its antioxidant and whitening effect is less stable, so the homemade natural whitening mask is not effective.
3. Homemade whitening essence is easy to contain bacteria
A website teaches people to make whitening essence. The materials include: L-C powder-1g, water-soluble vitamin E-0.5ml, pure water-9.5ml. These materials can be purchased from the chemical industry. Mix them evenly. Such a rude, suspicious effect, and some ingredients with whitening effect are irritating, plus the concentration of active ingredients contained in homemade skin care products can not be determined, if the concentration is too high, it will be dangerous. At the same time, the containers, materials used in the production, or the process may also be contaminated by bacteria. Plus no preservatives can not be sure of their shelf life, it is not recommended for everyone to use.
4. Serving pearl powder and white machine
Since childhood, I have heard that more pearl powder can make the skin white and smooth. Even the Empress Dowager Cixi is convinced. There are reports that a star has the habit of eating pearl powder since childhood. When growing up, he also keeps 1 teaspoon a week. Is it really feasible to raise your face? It is unfounded to take pearl powder whitening in nutrition. It is important to note that pearl powder will become inferior due to problems such as seawater pollution, and it is a mineral that may cause heavy metal residues, which may cause damage to the body. It is not recommended to take it indiscriminately.
5. Serve aloe vera whitening
Aloe vera can be whitened, although it may not be effective, but at least the ingredients are naturally harmless to the body. However, there are more than 300 varieties of aloe vera. There are ready-to-eat foods on the market, and there are also natural homemade foods. How to choose them? At present, the US FDA and the Chinese Department of Health allow only five kinds of aloes to be eaten and medicinal, including: Good Hope Aloe Vera, Aloe Vera, Queen Aloe Vera, African Aloe Vera, and Aloe Vera. External application of aloe vera has the effect of eliminating skin redness and swelling, and oral administration has laxative and detoxifying functions, thereby improving dullness or pigmentation of the skin. The serving size is recommended to eat 3 to 4 tablespoons per day. Because the concentration of different brands is different, it is safest to take according to the label guidelines. Because of the laxative effect, pregnant women should avoid eating. >>>Milk skin care formula makes you have milky skin
