I generally use hydrogen peroxide on cuts and scrapes, and as an alcohol, antibacterial, and antiseptic, it helps to kill off the bacteria that may well be hurting my skin and give me the generalized effects I am looking for.  This is why obviously it works so effectively as a way to clean cuts and wounds and prevent future infections.  But with how easily acne can turn into a cut or wound and attract infection, in fact acne is in part made up of infections, obviously you want to get rid of this.  It can get rid of discoloration, bacteria, excess oils, etc.  The thing to keep in mind however is that this alcohol can easily dry out the skin.  It is easily able to actually damage and break down the skin cells, and though it’s an easy way to get rid of bacteria that can be found anywhere, it isn’t always worth finding.  Sometimes it’s worth it to find something that’s gentler and yet still effective in so many ways.  It should always be remembered that it is still an alcohol and it will still therefore cause certain things that you may not actually want in your skincare regimen.
