My skin felt incredibly soft and smooth after using it! The effect was much more pronounced than other similar face masks I've tried. I really felt like my skin was thoroughly cleansed.
I purchased a couple sets of the zombie pack, and used about half of one set. While it felt nice right after using it, I didn't really see any lasting improvements. Plus, it's kind of a hassle to use - it's difficult to wash off, and using a scrubbing sponge was too irritating on my skin.
Applying an essence beforehand can help reduce the irritation a bit.
