The sunscreen's sunscreen has a lot to do with its sunscreen. How to match different sunscreens and how much they add will directly affect the sunscreen's sunscreen effect.

The country will also conduct random inspections on the sunscreens circulating on the market from time to time, but basically the random inspections are organic sunscreens, which are commonly referred to as chemical sunscreens. They will not randomly inspect inorganic sunscreens such as titanium dioxide and zinc oxide (commonly known as physical sunscreens).

Fudan University PhD in neurobiology and founder of hard-core skin care popular science public account "Ingredient Control", told Consumer Reports " : "Traditional inorganic sunscreens reflect ultraviolet rays most of the time because of their large particles. With the advancement of nanotechnology, nanoparticles of titanium dioxide and zinc oxide can also absorb ultraviolet rays and generate heat. But as long as they are not sprayed on the surface of the mucosal membrane, we usually believe that Inorganic sunscreen is impermeable. The working principle of organic sunscreen is to absorb the energy of ultraviolet rays and generate derivatives. Derivatives may have toxic side effects on the skin. Therefore, the country has corresponding testing for organic sunscreens to ensure product safety. "

. The reasons for the failure of this type of product random inspection are mostly two situations: detected the approval documents and unlabeled sunscreens, unlabeled the approval documents and unlabeled sunscreens.

This time, this magazine sent 12 sunscreens to third-party authoritative testing institutions based on the testing methods of sunscreens in the "Technical Specifications for Cosmetics Safety" (2015 edition), and a total of 18 sunscreens were tested. The results showed that the types and content of sunscreens in the 11 sunscreens met national requirements.

Among them, MistineMistine Hydrating and Clear Sunscreen (Batch MFG 2159022C EXP 20250607, purchased from Tmall Mistine Cosmetics Flagship Store, 60ml) Application and unlabeled sunscreen zinc oxide , with a content of 9.97%, which does not comply with national regulations and is rated as a product that is not up to standard.

Single sunscreen is generally difficult to achieve good sun protection effects, and each sunscreen has a limit on usage restrictions. Therefore, most sunscreens are used in combination with multiple sunscreens to achieve better broad-spectrum sun protection effects. After sunscreen is tested, once the sunscreen is inconsistent with its label and approval documents in , it is suspected of violating the relevant provisions in the " Cosmetic Registration and Filing Management Measures " and the " Cosmetic Supervision and Administration Regulations ".

. This magazine also tested another batch of the same sunscreen from Misting (batch MFG 2115030B EXP 20250424, purchased from Misting JD.com self-operated flagship store, 40ml). The test results showed that zinc oxide was not detected. The results of the sunscreen zinc oxide detected in the two batches of are completely different.

Executive Vice President of Guangdong Cosmetics Science and Technology Research Association and Senior Engineer of Daily Chemicals Zhang Taijun analyzed that the common reason for this phenomenon may be that the company has changed the formula without authorization.

He pointed out that the safety of the special product formula is closely related to the formula composition. In order to ensure the health and safety of consumers, the registered formula and the production formula must be consistent in order to give full play to the significance of expert technical review to provide protection for consumers' health. If is changed at will, it will bring hidden dangers to consumer safety ; and because of cost, supply chain guarantee, and consumer complaints about skin feeling may give rise to individual brands with weak awareness of the rule of law to change the formula without authorization.

"It is also possible that material feeding errors, material feeding errors, inaccurate measurements, or poor quality of raw materials purchases, and confusion of raw materials may also cause a certain degree of fluctuation in the volume of addition or inconsistent with the label. Of course, these situations are relatively slight." Zhang Taijun told consumers.

Regarding the test results of Misting's sunscreen, this magazine interviewed its affiliated company, Bitewei (Shenzhen) Cosmetics Co., Ltd., and no reply was received as of press time.

Anressa ANESSA sunscreen contents are quite different in different batches of sunscreen

This sunscreen test, this magazine also added the same sample or different batches of formal wear for testing. Among them, Anressa, L'Oreal, Shiseido, Perchoa, Neutrogena, Winona, 934, and ALLIE Aili are sample products, and Misting, UNNY CLUB Youyi, Huaxizi, and Xinbi are formal wear products in different batches. The titanium dioxide content of sunscreen is 0.267% and 0.99% respectively, 0.723% difference is the content of sunscreens in most samples or in different batches of formal wear. The content of sunscreens in the ANESSA Jincanbe sunscreen milk in formal wear and sample (formerly wear batch: 1215DD-S; sample batch: 1224KD-C), the content of sunscreen agent titanium dioxide is 0.267% and 0.99% respectively, with a difference of 0.723%. The content of sample is 3.7 times that of formal wear . Since the base of titanium dioxide is added in its own small amount, 0.723% is a relatively large gap.

Anresha ANESSA Jincanbe sunscreen label indicates: double-layer type, please shake the bottle body up and down hard before use. In this sunscreen test, the testing mechanism fully shakes the bottles of all sunscreen samples, including the sample, before sampling to ensure even sampling.

However, there is a significant difference in the titanium dioxide content detected by Anresha's formal wear and the sample. In this regard, Peng Guanjie, R&D director of Fanke Biotechnology (Guangzhou) Co., Ltd. and senior cosmetic formula Peng Guanjie analyzed the reasons. If there is a difference in sunscreen between batches, it may be that the heating time during the production process is too long, resulting in excessive evaporation of moisture, and the concentration of titanium dioxide will also become relatively high; or the bottle mouth is poorly sealed and there is water leakage problem.

He told this magazine: "The above situations are very likely to be encountered in the quality control process, and the titanium dioxide content between different batches is 0.267% and 0.99%, respectively, which will directly affect the coverage and lead to different sun protection capabilities of the product."

The test results of Anresha formal wear and small sample titanium dioxide are similar to the test results of the titanium dioxide content of the Perchoa Feather Sense Sunscreen announced by the previous blogger "Big Tiger Class Representative", and there is also a gap of more than 3 times.

. The above two products have a common feature, which needs to be shaken and used.

In order to have a refreshing skin feeling, some sunscreen products appear in the form of "shaking fun", but this form brings quite a lot of risks.

Bao Feng said that to provide sun protection effect while ensuring the skin feeling, the first solution is to adopt the method of oil and water separation, commonly known as shaking music. The biggest disadvantage of Shakeleton may be that the mixing is not evenly enough, which leads to poor sun protection. If it is a sunscreen that is pre-mixed evenly, the probability of sunscreen spreading evenly on the face is higher, but its shortcomings may be that the skin feels too sticky and too thick.

, head of , Nanjing Kesi Chemical Co., Ltd., told consumer reports: "During the market sampling process, the content of the sampling sunscreen agent is occasionally high or low. In the case of regular production and regular testing, there are two possible reasons for the deviation."

"One is that during the production process, the sunscreen agent is not dispersed evenly, which is related to the dispersion method of the active active ingredients and the verification of production equipment. During the process of waiting for filling, sunscreens are deposited, such as shaking milk-based dilute emulsion products. If they stand for too long, the suspended sunscreens will slowly deposit, resulting in inconsistent content of sunscreens in the loading and unloading bodies. Therefore, they should be stirred evenly before filling. "

In addition to Anresha , there are also L'Oreal and ALLIE Aili products with some slight differences in the formal and small-sample sunscreens, both of which are about 1%.

In Peng Guanjie's view, it is normal for a higher amount of sunscreen, which has a gap of about 1% between different batches.

He pointed out that in order to obtain a high-power protection index, if the sunscreen effect of SPF50+ is achieved, the overall content of sunscreen is bound to increase. Therefore, many companies will compound chemical sunscreens with higher content when developing formulas. Different storage environments and storage times may lead to degradation of chemical sunscreens. Even in the same batch, there may be some differences in the content of some chemical sunscreens. However, inorganic sunscreens such as titanium dioxide and zinc oxide are relatively stable and generally do not degrade over time.

Zhang Taijun also said that a sunscreen product goes through a lot from production to market, to being randomly inspected to detection results. Due to factors such as the stability of the raw materials themselves, testing methods and testing personnel, it is very common for the added sunscreen to have certain errors.

In response to the test results, Jialibao Cosmetics (China) Co., Ltd., a company affiliated to ALLIE Aili Water Moisture Sunscreen Hydrocarb, replied to this magazine: "Our company implements quality assurance testing, complies with Chinese regulations, and the product has a quality guarantee of 3 years. At the same time, our company also implemented the time-change measurement of the ingredient concentration and confirmed that even with the time change, all ultraviolet absorber have not changed with the addition concentration at the beginning of the period."
