I just went to Korea and bought my mom a bottle of Bichup from the Lotte duty-free store, based on a review post I found here. So, it's definitely legit. However, when I got back to my home country in Southeast Asia and visited the Lotte Mall, I noticed the packaging was completely different. Has Whoo undergone a rebranding, or do they use different packaging for different regions?
Another sensitive question: some people say the Korean version of Whoo products has a higher concentration of key ingredients than the international versions shipped to other countries. They claim that the Korean version visibly performs much better on their skin. Some said even the version on the Korea street shops is different then the ones in the mall. For those who have tried different versions, did you notice any difference?
