No, 577 Zhenyimei is not a brand. As far as I know, I have never heard of the existence of 577 Zhenyimei as an independent brand, whether online or in a physical store.
After searching online, I didn't find any official website or social media accounts related to 577 Zhenyimei. Usually, a regular brand will have its own official channels to communicate with consumers and promote products, but for 577 Zhenyimei, there is no such thing.
I also referred to some professional beauty magazines and information websites, and searched for the contents about 577 Zhenyimei, but found no relevant reports or recommendations. For a well-known brand with a long reputation, it is usually concerned and reported by the media and professionals. However, for the beauty of 577, there is no such sign.
Furthermore, from the consumer's point of view, my friends and acquaintances have never mentioned the brand 577 Zhenyimei. We usually share our good products and shopping experiences, but we have never heard of anyone using or understanding 577. This reinforces my view that it is not a brand.
According to the information I got, I can confidently say that 577 Zhenyimei is not an independent brand. Although there may be some omissions in channels or information, from all aspects, including official channels, media reports and consumer word of mouth, there is not enough evidence to show that 577 Zhenyimei is a regular brand.
If you are interested in the origin of the name 577 Zhen Yi Mei, I can tell you that I didn't find any data or information directly related to it in my investigation. Maybe it's just a creative name or a random combination of letters and numbers, but it doesn't represent a real brand.
