Let me explain what I appreciate most about this foot mask. It's not how the formula is both hydrating and exfoliating, and warms up in minutes after you slip it on — although that is all true — but rather, it's that the liquid lining the inside of the foil sack doesn't extend up to the ankle area, like other foot masks I've tried, which makes it less messy to apply and far more conducive to use in the back of a moving vehicle. (Although, it's worth noting that this would also make it easier for at-home use, since it's very difficult having to sit like a statue like you have to wearing the other formulas.)
