Graymelin - kiizhhang review for Mugwort Heating Pack

Well, I love how it clean my pore and reduce white head and black but at the first time i was so surprised because it make me feel hot a bit on my face and i afraid that after i use it my face get red but it's not..! Yes it's okay to use for my sensitive skin and dry but i think we shouldn't put it more than 15 minutes if we have sensitive skin.
