Hyaluronic acid contact lens hot-selling network Beijing Youth Daily reporter survey found that the business can not prove the authenticity of the composition of hyaluronic acid lenses to


make the eyes more hydrated?

Doctor: gimmick

  In recent years, hyaluronic acid has frequently appeared in people's sight. In addition to medical beauty and other fields, oral hyaluronic acid products have also increased day by day. Nowadays, more businesses have launched hyaluronic acid contact lenses.

  A reporter from Beijing Youth Daily found that there are many cosmetic contact lenses with the name "Hyaluronic acid" on the e-commerce platform, claiming to make the eyes "long-lasting moisturizing" and "breathing freely."

As a result, many loyal fans of hyaluronic acid began to show great interest in this new product, placing orders one after another, pushing this product into a "net celebrity".

  Market performance

  27000 boxes sold in 30 minutes

  The monthly sales of celebrity endorsement brands exceed 100,000

  Some people with myopia choose contact lenses for beauty, but they are prone to uncomfortable conditions such as dry eyes when worn for a long time. In view of the market recognition of "Hyaluronic acid" in moisturizing and moisturizing, many businesses have sold hyaluronic acid lenses, which are under publicity. There is no shortage of keywords such as "have the function of locking in moisture, making the eyes more hydrated and comfortable".

  During the pre-sale period of the 618, a hyaluronic acid cosmetic contact lens with "long-lasting moisturizing" and "free breathing" selling points attracted widespread attention. According to the brand's official introduction, 27,000 boxes were sold in 30 minutes.

And claimed that it is the first domestic brand to introduce hyaluronic acid component technology into cosmetic contact lenses.

  It also claimed that the product development team fully unlocked the water retention effect of hyaluronic acid, allowing the hyaluronic acid-containing cosmetic contact lenses to exhibit 1000 times the water absorption as much as possible, achieving a super-sensory experience of keeping the eyes moisturized for a long time and breathing freely. International health efficacy certification.

  A reporter from the Beijing Youth Daily searched through keywords on the e-commerce platform and found 8 brands that sell hyaluronic acid cosmetic contact lenses, most of which are daily disposable. The price of 10 cosmetic contact lenses is between 60 and 80 yuan, which is more beautiful than ordinary daily disposables. Hitomi's price is slightly higher.

  Business statement

  Each family is not consistent

  Can't prove that the lens contains hyaluronic acid

  Many businesses said that hyaluronic acid cosmetic contact lenses are new products, but their opinions are not consistent as to where the hyaluronic acid ingredients exist.

Some say it contains hyaluronic acid in the lens, but it has not recovered the principle of action.

There are also claims that this ingredient is contained in the lens preservation solution. “The beauty contact lens itself does not contain hyaluronic acid, so the ingredients on the package will not write hyaluronic acid.” The customer service of a celebrity endorsed product explained.

  In the live broadcast room, an anchor is promoting contact lenses. When asked if there are hyaluronic acid lenses, the anchor immediately recommended that this product is their special black-technology lenses. You can check the product patent certification from the customer service. The so-called hyaluronic acid cosmetic contact lenses do not contain hyaluronic acid in the lens, but add hyaluronic acid water molecules to the preservation solution, which are attached to the surface of the lens. After wearing it, it can lock water and moisturize the eyes, and will not dry the eyes.

  Subsequently, a reporter from the Beijing Youth Daily asked for a product patent certificate from the customer service, but the other party sent the company's medical device business license and Internet drug information service qualification certificate.

After repeated questioning by the reporter, the customer service said that there is no product patent number, but hyaluronic acid will be written in the product packaging, and the qualification will not be reflected.

  However, the reporter noticed that the brand officially released the introduction of hyaluronic acid lenses on October 17, 2019. It was said at the time that “Hyaluronic acid lenses are made with hyaluronic acid added to the lenses. Hyaluronic acid has a very good moisture-locking function. Hyaluronic acid cosmetic contact lenses can make the eyes more hydrated and comfortable.” And in the slogan, “I won’t feel dry eyes even after working for more than ten hours”.

  When the reporter asked the customer service about this publicity statement again, the other party sent a product link and still replied that it was the hyaluronic acid in the preservation solution, not the hyaluronic acid in the lens.

  Check the authenticity

  It's just a publicity stunt for the business

  Cosmetic contact lenses actually don’t need hyaluronic acid

  Does the cosmetic contact lenses contain hyaluronic acid or does the cosmetic contact lenses themselves contain hyaluronic acid?

Do these two methods really make the eyes more hydrated and moisturized?

  A business who has been acting as a cosmetic contact agent for 5 years clearly told the reporter from Beijing Youth Daily that hyaluronic acid cosmetic contact lenses are just a publicity stunt for the business. "Generally, preservation solutions are used to disinfect and provide a sterile environment. Normal saline is commonly used. Me. I have never heard of the addition of hyaluronic acid to the preservation solution, which is not very reasonable."

  Guo Xueping, a scholar undertaking research on hyaluronic acid and a researcher in pharmaceutical engineering at the School of Pharmacy of Shandong University, told the Beijing Youth Daily that there have been related reports and academic papers proposing to add hyaluronic acid to contact lens lenses, but this technology is still in the research stage and is now on the market. There is no such product on the market.

But as for the effect of adding hyaluronic acid to the preservation solution, he believes that it depends mainly on the consumer's experience, and it is difficult to draw a clear conclusion.

  Wang Shulin, deputy chief physician of Henan Provincial Eye Hospital, also said that the so-called "cosmetic contact lenses" are medically called colored soft contact lenses.

It should be emphasized that contact lenses are classified as three types of medical devices.

At present, there is no process for adding "hyaluronic acid" to "cosmetic contact lenses". Even if it can be achieved by the process, it is actually not necessary.

  "Because from the technological point of view, the materials used to make soft contact lenses need to reach an appropriate water content and have good oxygen permeability, so that they are more comfortable to wear. At present, the commonly used materials are silicon hydrogel, Hydroxyethyl methacrylate, etc. In other words, the water content of soft contact lenses should be moderate, not the higher the better, so there is no need to add sodium hyaluronate or sodium hyaluronate." He also said in " The addition of "hyaluronic acid" to "cosmetic contact lenses" is nonsense and a gimmick that "takes for granted" after changing the concept.

  Similarly, he believes that the claim that certain businesses "preservation liquid contains hyaluronic acid, which can dissolve on the lens to achieve a moisturizing effect", Wang Shulin also believes that it is unreasonable.

  He introduced that the cleaner and smoother the surface of the contact lens lens is, the better. The chemical components in the preservation solution can play a role in moisturizing and disinfecting.

If "Hyaluronic acid" is added to the preservation solution, it may not be harmful to moisturizing, but "Hyaluronic acid" will definitely not dissolve on the lens.

  According to Yun Wuxin, Ph.D. of Food Engineering, in the promotion of hyaluronic acid foods, he often sees "According to multiple studies, hyaluronic acid can improve the moisture of human skin through oral administration of hyaluronic acid such as foods and health foods, and it has anti-oxidation in the body and improves joint function. Osteoporosis, repair gastric mucosal damage, etc., and have high safety."

  He believes that this "multiple studies" is just casually saying that there are almost no real rigorous and reliable human experiments.

In 2012, a company declared to the European Food Safety Authority (EFSA) the energy efficiency claim of "Oral Hyaluronic Acid Skin Care", which was rejected by EFSA's expert committee. The evaluation concluded that "there is no human experiment to support the declared function". There is no causal relationship between hyaluronic acid and skin protection".

  Ma Guiji, a lawyer at Beijing Chuangwei Law Firm, stated that the information provided by operators to consumers about the quality, performance, purpose, and expiration date of goods or services should be true and comprehensive, and no false or misleading publicity should be allowed.

The main concept of hyaluronic acid is called "hyaluronic acid cosmetic contact lenses" in the promotion, but it is not clearly indicated in the ingredients. This operation of the merchant is not only easy to misunderstand consumers, but also suspected of fraud.

  What is hyaluronic acid?

  According to experts, hyaluronic acid is a substance separated from the vitreous body of a bull's eye by American scientists in 1934, and later determined that its chemical structure is a mucopolysaccharide.

  A certain amount of hyaluronic acid naturally exists in animals, such as bull's eye, cockscomb and so on.

In the early days, hyaluronic acid was separated from these tissues.

Hyaluronic acid currently on the market is produced through fermentation, which can be produced on a low-cost and large-scale basis, and has a foundation for widespread use.

  The "talent" of hyaluronic acid is that it is extremely water-absorbent. The macromolecular hyaluronic acid can absorb 1000 times the weight of water to form an extremely delicate and lubricating gel.

This feature makes it used in various ophthalmic operations, such as lens implantation, corneal transplantation and anti-glaucoma surgery.

In addition, through injection, it can also be used for arthritis, skin care, etc.

  According to Wu Yan, chief physician of the Department of Dermatology, Peking University First Hospital, 50% of the hyaluronic acid in the human body is distributed in the skin. Hyaluronic acid has a strong water absorption capacity and can combine with water 1,000 times its own weight.

At present, hyaluronic acid is indeed the "net celebrity" ingredient of cosmetics.
