That's a difficult question to answer. It's somewhat prevented by skin maintenance, but most acne cases are hereditary, stress related, or hormonal. If you're eating a balanced diet and the acne is not really related to dirty skin, you can't scrub it off. You can try to treat it early on before it leaves scars. Never pick at acne. It will only aggravate it and make it scar more. Early intervention treatment is most important. Dermatologists spend three extra years in medical training to learn how to maximize the right combination of treatments. Retinoic acids are very effective in treating the red, inflamed cystic bumps, so I think the key message is to see a board certified dermatologist before scarring results.
