Different things work for different people. Try different things until you find something that works.
But I'll tell you what's NOT a good cure to acne... OXY 10.
OH SERVER MY FACE, MY FACE!!
I've been fighting off the acne all my life. I almost had it gone, I was happy with my progress. That was, until I ran into this hot guy at work. He also has a habit of standing a little closer than I'm used to. At that time I desperately wished like hell that my acne was properly gone, and I got impatient for a solution. I resolved that I would find a solution, and knock this problem on the head once and for all!
Later that night, I was walking through the chemist and I saw it. It looked like the solution to the last of my stubborn acne. I thought - If OXY 5 is good, then OXY 10 has got to be TWICE as good, right?
Mistake.
Several days of use, and I thought I was breaking out. I'd heard rumors that it'd make acne worse before it got better. Then I read on the internet, that the stuff really worked well and "some flaking, itching and redness is normal until your skin gets used to it", and "You should use it all over to prevent breakouts, not just on the spots". So I did.
Big mistake.
So, I kept using it for a week. All over my face. It looked to be getting worse, so I stepped it up to twice a day to try and clear this "impending breakout".
Bigger mistake.
A week later and what I thought was the beginnings of a major breakout was contact dermatitis. Puffy, red, and threatening to start peeling. Even my ears and down my neck - places I never used it.
To add insult to injury, it had bleached my facial hair and I had to shave it off.
So I ended up red, puffy, itchy, almost peely, and facial hair-less. And I still had the acne underneath it all.
The moral to my story - 10% peroxide is strong stuff. Avoid. If not, use it sparingly, not every day, DEFINITELY NOT twice a day. Don't get impatient waiting for clearups and use more stuff than your skin can handle. If you see red or feel itchy, stop using something.
It took 2 weeks of gentle cleansers, and smearing my face in sorbalene twice a day to fix that mistake (it's cheap, kinda heavy, but a VERY effective moisturizer). Oh, and some over the counter steroid cream. It's been 3 weeks since the mistake, and my neck is still slightly red.
But hey, at least I didn't run into the person that caused me to lose my patience during that screwup - so no harm, no foul
