My skin has never been really bad, but my habits have been. I often used to scratch and pick at sores, and compulsively squeeze pimples. This caused moderate spreading of infections for me. These days I just wont touch my face for those purposes. If I have to "pop" something, I'll get a needle/pin and I'll sterilize it with something like Hydrogen Peroxide or high-percentage rubbing alcohol (Isopropyl). It's worth noting that Ethanol/Isopropyl Alcohol etc. do not kill the spores of fungi, so a combination cleanse can be more effective. Alcohol can really dry your skin out though, so I usually use a bit of Vitamin E later, but if your face is covered in Acne, I wouldn't risk rubbing the Vitamin E (you could spread more?), so maybe dilute it into a spray and apply it lightly. Avoid shaving if you can; until you're on top of the acne/bacteria infestation.
