Great sheet mask.
I really liked these.  I had not used the sheet masks before so I ordered several different brands.  My main point of comparison was my crows feet around my eyes. The Dermal Premium Collagen were the 3rd brand of masks I tried and I really liked them.  They seemed to work a lot better than the Dermal Regular.  The TonyMolyPureness 100 were good as well.  It seems like if you spend just a little more you get a better bang for your buck.  I normally use them at night either while watching TV or reading in bed.  I will definatley order these again.
