I love using this treatment right after I apply a low pH toner. I let it sit for 15-20 minutes to fully absorb and work its magic before I apply serums and moisturizers. With consistent use, I have found that it helps smooth out my skin and get rid of small, bumpy textures. I wouldn't say that this is a cure all for people who have severe acne and acne scarring but it does help to a degree. It also helps calm down those monthly hormonal acne that is deep under the skin and inflammed. Give it time to work though, it doesn't go away overnight but it does help bring it down faster. I use this by alternating this treatment fluid with the BHA fluid. I highly recommend that you use sunscreen daily if you start using this product since it makes your skin sun sensitive. Lastly, if you feel it stinging a bit as you apply, it's ok. The stinging won't last long and your skin will adjust to it over time.
