Can anyone tell me why the first one is more expensive than the second one? What's the difference between those two exfoliators?

The ingredients.

The cheap one contains Manmade polyethylene beads, it removes dead skin cells, just regular cleanser.
Expensive one contains aluminum oxide micro-crystals, beside it works as a cleanser, it has anti-aging properties too.

The only difference I see is that the one that costs more is for dry skin.
