I use this peeling pack.

This is the Baby Face Collagen Mild Peeling Pack. I usually have a lot of dead skin cells, and perhaps because it's summer, my skin is in terrible condition due to excess sebum. However, using this peeling pack removes dead skin cells easily. It comes in a standard sheet mask form; I just leave it on for about a minute and gently rub it, and the exfoliation works really well. Afterwards, I just rinse with water, and my skin feels soft and smooth. It is also moisturizing, so it isn't very irritating.
