This works really well! Dab it onto a problem spot with a qtip and wait overnight and there is a definite difference in the morning after you wash your face. It reduces redness of the spot as well, and usually spots for me go away after 2-3 days when I use this. Only works for surface spots though, not really much for cystic/deep pimples! It seems as if it would last a while, and I really like how unlike others that I've tried, once this is dry on my face it doesn't rub off on my pillow. Would for sure repurchase!
