Not for me

I have been trying the various masks that Shoppers Drug Mart sells, usually they are 3 for $5.00, First thing I noted is that the white mask was sopping wet with the gel like liquid and also the mask was really cold while applied and stayed cold for the full 15 minutes and it sort of tingled. I had heard it stung for others, but not in my case, I had no skin irritation whatsoever.
It really hydrated my skin but I'm not convinced it cleaned out my pores. I thought that the mask might dry and when removed it would pull out the dirt and unclog my pores, which it did not. Days after use my pores looked the same and I still had visible black heads, for this reason I probably would not purchase this specific sheet mask again
