I think I'll be half confident. Originally, advertisements are exaggerated and furthermore, there are quite a few false ones. Of course, Korea strictly regulates such things and attaches data such as reliable experimental results, but there are often exaggerated or false ads. But I think people who are in that situation will believe it. People who think wrinkles are a complex or order can be trusted becasue they want to remove them and slow the aging process, but others may not be interested in wrinkles or aging.
