Is it worth a spot on your shelf?

A rice-based powder exfoliant that you mix with water before applying.

The appeal: The water-activated format combines a polishing powder with papain and salicylic acid. It is a different routine from using a ready-made liquid exfoliant. Dermalogica

The tradeoff: You need to dispense and mix it each time. If you prefer a single ready-to-use step, that extra handling may outweigh the appeal of the powder format.

Our take: A good format to explore if you like mixing a fresh paste; the mini is an easier place to start if you are unsure.
