'China on the tip of the tongue 3', which has made the audience wait for more than three years, has caused a lot of controversy since it was launched on the fourth day of the new year. Especially after the 4th th episode of 'yang' was broadcast, the self-made 'traditional Chinese medicine lipstick' that appeared during it caused a lot of criticism from netizens, and Douban score also started from 8. 0 points plummeted to 5. 7 points. Regarding the homemade Chinese medicine lipstick, netizens questioned more about its 'safety '. Ji Huihui, chief dermatologist of Nanjing Hospital of Traditional Chinese Medicine, said that regular products are completed in a series of production processes in a sterile environment, and can only be put on the market through repeated hypoallergenic tests and efficacy tests. However, self-made cosmetics have no sterile environment and do not add preservatives. Therefore, the probability of bacterial growth will be relatively increased. Therefore, self-made cosmetics are easy to deteriorate and have a short storage time. Pure Natural without adding 'does not exist', 'the so-called pure natural hand-made skin care products, is not to add any lead and mercury and other harmful chemicals, so naturally 99% of people use no problem. 'On Taobao, many shopkeepers interpret the safety of homemade skin care products. And many people understand pure natural cosmetics: chemical = harmful, pure natural = harmless. It is probably that it is picked from high-end plants in various high-end areas, extracted from the essence of the point, and then distilled by what method, the achievement of pure natural cosmetics. Everyone thinks that pure natural skin care products are natural and non-irritating, and are taken from nature, so they are particularly assured. Ji Huihui told reporters that in fact, cosmetics can't be pure natural: Chemistry is not necessarily harmful. What we call pure natural is non-synthetic materials. The so-called pure natural, in fact, is still synthetic. The source is natural materials, but it is not equal to pure natural. Cosmetics are also impossible to pursue pure natural. The molecules in natural materials are usually large and contain harmful and sensitizing substances. Moreover, the purification of natural substances is not easy, and some of them are photosensitive and phototoxic, which are far less stable than chemicals. Why do you say that pure natural skin care products do not exist? 'Preservatives are generally required in skin care products, otherwise it is difficult to ensure that skin care products do not rot during use. Rotten skin care products are more harmful to the skin than preservatives. The preservative is synthetic. If no preservatives are added, it is necessary to ensure that the whole process of producing skin care products must be in a sterile environment, which puts extremely high requirements on the supply chain, and the price of the products will be very high. The so-called 'extracted from plant essential', we have no way to know the extraction method, freshness and the actual content of the active ingredients, so even if the plant ingredients with the same name are added, the use effect will also be quite different. 'Ji Huihui said. Therefore, when facing 'pure natural skin care products', it is necessary to pay attention to 120 thousand points and carefully screen them. Don't be blinded by the three words 'pure natural. The risk of bacterial infection in the self-made process many people think that the self-made cosmetics are clear about their contents and components, and they are more comfortable to use. However, it ignores the potential health risks of these beauty products in the process of self-control. For example, if ordinary tap water is used in the process of self-made cosmetics, although tap water is purified and disinfected, it does not mean it is completely sterile. There is also juice mixed with oil or extracted from plants, which will inadvertently provide rich nutrition to those bacteria and make them multiply rapidly. If such products are applied to damaged skin, the probability of infection will increase. Ji Huihui said that if you make your own cosmetics, you can't guarantee a sterile environment, and you won't add preservatives. Therefore, the probability of bacterial growth will be relatively increased. Therefore, homemade cosmetics are easy to deteriorate and have a short storage time. More can't believe in small workshops because the equipment and technology of small workshops are not advanced enough and the degree of sterilization is not enough. The use of impure water in the production process, coupled with the addition of some oils or plant extracts inadvertently provide bacteria with rich nutrition, providing a hotbed for bacteria to cause rapid bacterial reproduction. In this case, there must be a safety hazard in the production. If there is no such understanding, and the corrupt and moldy homemade cosmetics are applied to the face, the consequences will be very serious. Ji Huihui told reporters: 'There are still many taboos in self-made cosmetics. For example, although fruits and vegetables are pure plants and do not contain any preservatives and chemical ingredients, they cannot be directly applied to the face, people with sensitive skin may cause irritation, redness and other allergic symptoms. There are also some light-sensitive Chinese medicines, such as Dahurian Angelica, which, although containing whitening effect, directly contact the skin surface and will produce light-sensitive dermatitis after encountering sunlight, causes symptoms such as redness, papules and blisters on the face.
