"No, it won't. Kouzi products are made of natural materials. You can do a test if you want." Gu Ning said, "Many women have searched the Internet for comments on Kouzi just now. Kouzi has been established for a while. If there are really side effects, there would definitely be negative comments. Kouzi has built its reputation on safety and quality."

Gu Ning had enough confidence to say that, so people were convinced by her.
