I've been using this at least once a week since July and I have barely made a dent in the jar! This clay mask is very gentle and hasn't irritated or dried out my skin at all. You only need a thin layer. It spreads and washes off really easily so you don't need to tug or rub at your skin. I usually apply my BHA toner about 20 minutes before I do this mask and it leaves my skin baby smooth and my pores really clean, particularly on my nose and the sides of my nose on my cheeks, where my pores are bigger. I would definitely repurchase this once I run out (probably not anytime soon!) or when the product dries out, which is more likely to happen. Definitely give this a try, it's inexpensive but very effective.
