A pea size amount is more than enough to clean your entire face. I love the feel of the baking powder scrubbing against the skin because it feels like micro micro-beads just dissolve.

It does leave my skin and pores feeling completely clean (blackheads on nose are still there though) and dry like I just applied a primer. I have also used Mizon's Snail Foam that also made my skin feel very clean but did not leave my skin dry, so there is a tradeoff when deciding which to use that morning/night.

Will definitely repurchase
