"Are you sure you didn't use any other skincare products from other brands?" Ning Changkai asked again.
"Of course not," the woman said with certainty.
"Well, I think it's very easy to find out whether it's Kouzi facial mask, which caused the rash on your face. Please try a piece of Kouzi facial mask right here right now to see its effect. If your face doesn't get better, it proves that the problem is our facial mask, but your accusation won't stand if your face gets better," Ning Changkai stared straight at her with a serious face.
Hearing that, a touch of panic flashed by the woman's eyes, but she still argued. "What if my face gets worse or is even disfigured by your facial mask?"
"Then we'll do whatever you want," Ning Changkai said with confidence, because he believed that there was nothing wrong with Kouzi's skincare products.
