I think the quality is very good. First of all, from a brand historical perspective, Bellona has 15 years of brand accumulation and can withstand the test of the market; secondly, from a technical perspective, Bellona has the patented technology of "transdermal short peptide" by Professor Wen Longping of the Chinese Academy of Sciences; finally, we I have two friends who own beauty shops and they often talk about this brand. I guess it’s not bad and you can learn more about it yourself.
