I want to declare that I didn't see the product you bought with my own eyes, so I'm not 100% sure of its authenticity. But according to my experience and understanding of the market, I can give some opinions for your reference.
Judging from the price, 280 yuan is neither too cheap nor too expensive. The price of authentic skin care products in Korea is generally between tens and hundreds of yuan, so there is no obvious problem with this price. Although some fakes will set a relatively high price to mislead consumers, it does not rule out real discounts or promotions. Therefore, it is not accurate enough to judge whether it is genuine from the price alone.
You can judge the authenticity of a product by some indicators. First of all, it depends on whether the packaging and logo are complete, clear and standardized. Products sold through formal channels usually have special packaging design and logo, while fake packaging often has problems such as ambiguity and poor printing quality. Secondly, it is necessary to observe whether the texture and smell of the product are true or false. Authentic products are usually delicate in texture and will smell different from fakes. You can also pay attention to whether the information such as product number and production batch is true and credible. If you can find relevant information through official channels, you can basically be sure that it is genuine.
You can refer to it through the comments of other consumers on the Internet. If many people have praised this product, then its authenticity is relatively high. On the contrary, if many consumers report that it is fake or the effect is not good, they should be vigilant.
When purchasing skin care products, we must choose reliable channels and carefully observe the details and quality of the products. If you are still skeptical about the products you bought, I suggest you contact the seller or official customer service for consultation and confirmation.
Going back to this snail essence water emulsion 280, I consulted some materials and found that it is indeed a popular product. Contains snail mucus extract, which has good moisturizing and skin repair effects. Many used consumers are full of praise for its effect and think that the skin becomes more moist and elastic. So, if what you buy is genuine, I believe it will bring you a surprise.
I want to emphasize again that the above suggestions are only based on some common sense and experience, and there is no guarantee that what you buy is genuine. When buying skin care products online, we should pay more attention, compare more and choose reliable channels to buy them. If you still have doubts about the authenticity of the product, it is recommended that you contact the seller or official customer service for consultation and confirmation. I hope my answer is helpful to you!
