A banana facial with a bit of honey may help with minimizing the appearance of acne and help in the healing process. Just smash a banana and mix a bit of honey with, apply it to your face after you've washed it, and leave it on for at least 15 minutes.
Let me ask you this question, do you sweat regularly? Such as intense exercising that allows your body to release excess sodium and toxins from your skins pours. At least try to get somewhere between 3-5 intense exercise routines into your weekly routine. After a few weeks you will see a major difference with your acne. However, if you already do sweat a lot then I'd try drinking more water and eliminate as much sugar and sodium from your diet as possible.
