Great for Spot treatment. Dries up cystic acne within a couple of days. However, the bright pink formula is definitely noticeable and cannot be worn under makeup. I could use this only at night, which is why it got 4 stars. I have forgotten to rinse it off a couple of times when I've run out the door in the morning (without makeup), only to realize by the afternoon that no-one told me I had noticeable pink spots all over my face all day. A little embarrassing.
