May I ask you a question? Are they (很多很多针尖大小的小颗粒) finally gone now? I also found them on my face, althought I didn't use 绿泥, I used sea marine mud mask from h2oplus (the blue one) twice. I also felt pain at the first time, but it was much better in the second time. Actually I just used them in T- zone. However there are some 针尖大小的小颗粒 on the cheek close to nose. They were at the edge of my mask using. I don't know whether it is caused by mask or not. If you have any experience about their cause or removement, could you share it with me? Many many thanks.
