The previous Hongyan Youth formula was relatively elementary, and the effect was good enough for ordinary people.
However, there was a problem with Hongyan Youth.
If you stopped using it, your skin would go back to its previous state after a while.
After all, all the herbs used were ordinary and could only have an ordinary effect.
This was not so with multiple-leaf grass, which was a spiritual plant!
If the leaves of multiple-leaf grass were used to make medicine, the customers could maintain youth for at least ten years.
So, if this kind of thing was known, people would definitely go crazy!
This was definitely something beyond imagination! It was not scientific!
Of course, Xia Xibei understood the importance, and she would not market it.
However, this could be used as a gift.
If Qiao Yanjue's mother was satisfied and happy, everyone would be better off afterward.
