Finished two bottles now. Before I replaced and didn’t use I think my skin suffered a little. I refuse to try a lot of acne things because they are often harsh and can damage moisture barrier. This one is very gentle but I still think it does something. Obviously acne is best fixed with dietary changes and some hygiene improvements but this is still great for me and having all that already cleaned up this is a next level thing to use on top of having a good regimen.
