is 3W Clinic actually a legit brand?

I've been curious about this since last year. 3W clinic is very well known with their amazing sunblock cream with very affordable price. I used that sunblock cream and i've used up almost 4 tubes? It's how good it is. But after my 4th tube, I decided to find out more information about the brand, the company that owns it, etc for my youtube contents purposes. But, it was slightly strange as the website for www.3wclinic.com isnt really a convincing website for me.(gives off the wordpress like site?) The "contact us" only has 1 gmail address which is www.3wclinic@gmail.com and the address was written as Huntington Beach CA USA? And also, note that you can't find any details about any products they have on their site. I did google some info and it is said that 3w Clinic is owned by a Korean Cosmetic company called XAI Korea founded in 2008. I went to XAI Korea IG but the last update was in 2018. I'm clueless here and if any of you might know the answer to my question, please let me know 🙏 also i'd like to apologise beforehand if any of the info i found here is incorrect. thank you
