I loved this product and used it alongside my Blackhead Clearing Fizz Mask. I had never used Dermalogica products before but I had heard good things from friends. I was excited to try this for myself. After using the mask, I used the breakout booster a couple times a week. After a week my breakouts had reduced drastically and my redness vanished. I only had a couple of spots but I was amazed by the outcome. I would 100% purchase this in future. I was lucky enough to receive this complimentary of Influenster, just in time for when my skin was at its worst.
