I bought the green tea and potato ones to help with my dry and irritated skin and it did help a lot! Despite the masks weird shape (especially around the nose and chin?), they have plenty of essence and leave the skin refreshed and moisturized; they feel really good. I haven't noticed a big difference between the green tea ones and potato ones yet except that the potato one seems a bit thicker and the green tea one smells a bit...nicer/fresher?

I recommend those, they're cheap but good!
