There are some things in Bilijian B family, just like if we usually eat other B vitamins, the urine will turn yellow.
As for acne, I think it may not be because of Billy Jian, but because of your body cycle or something.
I suggest that if you choose to eat, you can rest assured and keep a happy mood to accept it. If you doubt whether this thing really works every day, this thing is not what you want. It will have a negative effect on you, so it's better not to eat it.
Have you ever heard a saying that people don't doubt, people don't doubt, and so do things. Mood is very important
I wish you an early understanding
