This is great stuff. I purchased it after I started using the acne starter kit and really like it. It's a serum that is used for problem areas only. The serum is a bit sticky so I use it before I go to bed so that it works during the night. It helps with redness and I noticed that when I feel swelling or inflammation, with a blemish that hasn't reached the surface yet, it reduces the tenderness and redness which I love. When I use it at night it takes the tenderness away and I can see that the blemish doesn't come up. If i have some inflammation in the morning I will apply a small amount on the problem area under my makeup. Like I said it has a bit of a sticky texture but it doesn't get to sticky if you use a small amount under makeup. Overall great product.
