It can be used, but it can only be used if the thread is removed. My friend cut off her double eyelids before, and she waited for almost the same time, and then she applied this mask. She said that this mask is not bad, and there are some pimples on her face. After applying this mask several times, I feel that many pimples have subsided. My friend also recommended their bamboo charcoal mask to me. It is very comfortable after oil control, and it has a lot of essence. I'm waiting for this mask.
