Nowadays, light medical beauty has become the "standard" for many beauty lovers, and injection beauty is especially popular. There are many kinds of injection products. How to choose them safely? When choosing products and services, is the more expensive the better? Network information is uneven. How to choose reliable doctors and institutions? Experts remind that before the injection of beauty, these "lessons" of scientific beauty should be done in advance. Injection beauty has become a popular choice. How to avoid using fake products? Flexible method, small trauma, low risk and quick effect... Compared with surgical beauty, light medical beauty has won the public's favor with its significant advantages. According to the 2021 white paper on medical and beauty industry (hereinafter referred to as the white paper) released by the new oxygen data research institute, the proportion of light medical and beauty users continued to rise from 72.6% to 83.1% from 2019 to 2021. On August 18, according to the analysis report of China's injection medical and beauty industry in 2022 released by new oxygen, in 2021, the projects of tightening and anti-aging, wrinkle removing and thin face, and hyaluronic acid filling accounted for the largest proportion in the consumption scale, while the consumption of wrinkle removing and thin face mainly based on botulinum toxin injection was the project with the largest number of orders placed on the new oxygen platform in that year, accounting for nearly one fifth of the consumer population. The injectable medical and beauty projects represented by hyaluronic acid and botulinum toxin have "broken the circle" because of their convenience, high efficiency, low customer unit price and short recovery period. They have outstanding performance in medical and beauty projects and become popular choices for medical and beauty consumption. There are many kinds of injection products, even fish's eyes mixed with pearls. In this regard, Hao Lijun, director of the plastic surgery center of the First Affiliated Hospital of Harbin Medical University, reminded that due to the vigorous development of light medical beauty, the categories of related medical beauty products have become more and more abundant, and fake goods and parallel imports have also risen. There is a lot of room for formal products and compliant products to replace illegal products. Overall, the rate of fake and parallel imports of hyaluronic acid is the highest.

Han Sheng, President of Beijing Shouxi Lige medical beauty clinic, pointed out that regular medical beauty products must pass the certification of the State Drug Administration (nmpa) and need to have Chinese marks. Han Sheng stressed that formal institutions must be selected. The products of non formal medical and American institutions have evaded the national regulatory threshold, and the counterfeits and parallel imports are serious. In addition, counterfeits and parallel imports are generally characterized by excessively low prices or obvious marketing means. The printing of counterfeit medical and beauty products is often of poor quality, and there is no anti-counterfeiting QR code for reference. Injection beauty products and services the more expensive the better? Many beauty seekers are puzzled. When making choices, are the more expensive the products and services, the better? Is there a big difference in product quality between different prices? Han Sheng said that generally speaking, under the premise of formal medical and beauty institutions, the price of products and services is directly proportional to the services obtained by consumers. However, it does not rule out that some medical and beauty institutions have false marketing and profiteering marketing. Due to different kinds of products such as hyaluronic acid and botulinum toxin, there are differences between imported and domestic products, immature markets, and different doctor qualifications, there are large differences between products with different prices. At present, the pricing of medical and beauty projects is mainly based on the products. It is difficult to price the services clearly. When consumers choose high-priced hyaluronic acid, they will often enjoy high-quality technical services. Of course, the most important premise is
