I didn't have a good experience with Dear Klairs before so I was really holding my breath when I purchased this one. Thank heavens it went well with my skin this time! The appearance of my black heads improved (it hasn't gone away just yet, duh) and my skin feels SO soft. SO SOFT. Worth the money cause I only plan on exfoliating once a week so I'm sure I can make this last for 12M (its PAO/period after opened).
